• Problem on a Floyd-Warshall implementation using c++

  - by Henrique

  I've got a assignment for my college, already implemented Dijkstra and Bellman-Ford sucessfully, but i'm on trouble on this one. Everything looks fine, but it's not giving me the correct answer. Here's the code: void FloydWarshall() { //Also assume that n is the number of vertices and edgeCost(i,i) = 0 int path[500][500]; /* A 2-dimensional matrix. At each step in the algorithm, path[i][j] is the shortest path from i to j using intermediate vertices (1..k-1). Each path[i][j] is initialized to edgeCost(i,j) or infinity if there is no edge between i and j. */ for(int i = 0 ; i <= nvertices ; i++) for(int j = 0 ; j <= nvertices ; j++) path[i][j] = INFINITY; for(int j = 0 ; j < narestas ; j++) //narestas = number of edges { path[arestas[j]->v1][arestas[j]->v2] = arestas[j]->peso; //peso = weight of the edge (aresta = edge) path[arestas[j]->v2][arestas[j]->v1] = arestas[j]->peso; } for(int i = 0 ; i <= nvertices ; i++) //path(i, i) = 0 path[i][i] = 0; //test print, it's working fine //printf("\n\n\nResultado FloydWarshall:\n"); //for(int i = 1 ; i <= nvertices ; i++) // printf("distancia ao vertice %d: %d\n", i, path[1][i]); //heres the problem, it messes up, and even a edge who costs 4, and the minimum is 4, it prints 2. //for k = 1 to n for(int k = 1 ; k <= nvertices ; k++) //for i = 1 to n for(int i = 1 ; i <= nvertices ; i++) //for j := 1 to n for(int j = 1 ; j <= nvertices ; j++) if(path[i][j] > path[i][k] + path[k][j]) path[i][j] = path[i][k] + path[k][j]; printf("\n\n\nResultado FloydWarshall:\n"); for(int i = 1 ; i <= nvertices ; i++) printf("distancia ao vertice %d: %d\n", i, path[1][i]); } im using this graph example i've made: 6 7 1 2 4 1 5 1 2 3 1 2 5 2 5 6 3 6 4 6 3 4 2 means we have 6 vertices (1 to 6), and 7 edges (1,2) with weight 4... etc.. If anyone need more info, i'm up to giving it, just tired of looking at this code and not finding an error.

• Am I right about the differences between Floyd-Warshall, Dijkstra's and Bellman-Ford algorithms?

  - by Programming Noob

  I've been studying the three and I'm stating my inferences from them below. Could someone tell me if I have understood them accurately enough or not? Thank you. Dijkstra's algorithm is used only when you have a single source and you want to know the smallest path from one node to another, but fails in cases like this Floyd-Warshall's algorithm is used when any of all the nodes can be a source, so you want the shortest distance to reach any destination node from any source node. This only fails when there are negative cycles (this is the most important one. I mean, this is the one I'm least sure about:) 3.Bellman-Ford is used like Dijkstra's, when there is only one source. This can handle negative weights and its working is the same as Floyd-Warshall's except for one source, right? If you need to have a look, the corresponding algorithms are (courtesy Wikipedia): Bellman-Ford: procedure BellmanFord(list vertices, list edges, vertex source) // This implementation takes in a graph, represented as lists of vertices // and edges, and modifies the vertices so that their distance and // predecessor attributes store the shortest paths. // Step 1: initialize graph for each vertex v in vertices: if v is source then v.distance := 0 else v.distance := infinity v.predecessor := null // Step 2: relax edges repeatedly for i from 1 to size(vertices)-1: for each edge uv in edges: // uv is the edge from u to v u := uv.source v := uv.destination if u.distance + uv.weight < v.distance: v.distance := u.distance + uv.weight v.predecessor := u // Step 3: check for negative-weight cycles for each edge uv in edges: u := uv.source v := uv.destination if u.distance + uv.weight < v.distance: error "Graph contains a negative-weight cycle" Dijkstra: 1 function Dijkstra(Graph, source): 2 for each vertex v in Graph: // Initializations 3 dist[v] := infinity ; // Unknown distance function from 4 // source to v 5 previous[v] := undefined ; // Previous node in optimal path 6 // from source 7 8 dist[source] := 0 ; // Distance from source to source 9 Q := the set of all nodes in Graph ; // All nodes in the graph are 10 // unoptimized - thus are in Q 11 while Q is not empty: // The main loop 12 u := vertex in Q with smallest distance in dist[] ; // Start node in first case 13 if dist[u] = infinity: 14 break ; // all remaining vertices are 15 // inaccessible from source 16 17 remove u from Q ; 18 for each neighbor v of u: // where v has not yet been 19 removed from Q. 20 alt := dist[u] + dist_between(u, v) ; 21 if alt < dist[v]: // Relax (u,v,a) 22 dist[v] := alt ; 23 previous[v] := u ; 24 decrease-key v in Q; // Reorder v in the Queue 25 return dist; Floyd-Warshall: 1 /* Assume a function edgeCost(i,j) which returns the cost of the edge from i to j 2 (infinity if there is none). 3 Also assume that n is the number of vertices and edgeCost(i,i) = 0 4 */ 5 6 int path[][]; 7 /* A 2-dimensional matrix. At each step in the algorithm, path[i][j] is the shortest path 8 from i to j using intermediate vertices (1..k-1). Each path[i][j] is initialized to 9 edgeCost(i,j). 10 */ 11 12 procedure FloydWarshall () 13 for k := 1 to n 14 for i := 1 to n 15 for j := 1 to n 16 path[i][j] = min ( path[i][j], path[i][k]+path[k][j] );

• Podcast Show Notes: Collaborate 10 Wrap-Up - Part 1

  - by Bob Rhubart

  OK, I know last week I promised you a program featuring Oracle ACE Directors Mike van Alst (IT-Eye) and Jordan Braunstein (TUSC) and The Definitive Guide to SOA: Oracle Service Bus author Jeff Davies. But things happen. In this case, what happened was Collaborate 10 in Las Vegas. Prior to the event I asked Oracle ACE Director and OAUG board member Floyd Teter to see if he could round up a couple of people at the event for an impromtu interview over Skype (I was here in Cleveland) to get their impressions of the event. Listen to Part 1 Floyd, armed with his brand new iPad, went above and beyond the call of duty. At the appointed hour, which turned out to be about hour after the close of Collaborate 10,  Floyd had gathered nine other people to join him in a meeting room somewhere in the Mandalay Bay Convention Center. Here’s the entire roster: Floyd Teter - Project Manager at Jet Propulsion Lab, OAUG Board Blog | Twitter | LinkedIn | Oracle Mix | Oracle ACE Profile Mark Rittman - EMEA Technical Director and Co-Founder, Rittman Mead,  ODTUG Board Blog | Twitter | LinkedIn | Oracle Mix | Oracle ACE Profile Chet Justice - OBI Consultant at BI Wizards Blog | Twitter | LinkedIn | Oracle Mix | Oracle ACE Profile Elke Phelps - Oracle Applications DBA at Humana, OAUG SIG Chair Blog | LinkedIn | Oracle Mix | Book | Oracle ACE Profile Paul Jackson - Oracle Applications DBA at Humana Blog | LinkedIn | Oracle Mix | Book Srini Chavali - Enterprise Database & Tools Leader at Cummins, Inc Blog | LinkedIn | Oracle Mix Dave Ferguson – President, Oracle Applications Users Group LinkedIn | OAUG Profile John King - Owner, King Training Resources Website | LinkedIn | Oracle Mix Gavyn Whyte - Project Portfolio Manager at iFactory Consulting Blog | Twitter | LinkedIn | Oracle Mix John Nicholson - Channels & Alliances at Greenlight Technologies Website | LinkedIn Big thanks to Floyd for assembling the panelists and handling the on-scene MC/hosting duties.  Listen to Part 1 On a technical note, this discussion was conducted over Skype, using Floyd’s iPad, placed in the middle of the table.  During the call the audio was fantastic – the iPad did a remarkable job. Sadly, the Technology Gods were not smiling on me that day. The audio set-up that I tested successfully before the call failed to deliver when we first connected – I could hear the folks in Vegas, but they couldn’t hear me. A frantic, last-minute adjustment appeared to have fixed that problem, and the audio in my headphones from both sides of the conversation was loud and clear.  It wasn’t until I listened to the playback that I realized that something was wrong. So the audio for Vegas side of the discussion has about the same fidelity as a cell phone. It’s listenable, but disappointing when compared to what it sounded like during the discussion. Still, this was a one shot deal, and the roster of panelists and the resulting conversation was too good and too much fun to scrap just because of an unfortunate technical glitch.   Part 2 of this Collaborate 10 Wrap-Up will run next week. After that, it’s back on track with the previously scheduled program.

• Open FDF document on Mac

  - by Corey Floyd

  I'm having the issue documented here: http://forums.adobe.com/thread/445594 When I try to open a FDF, I just get a pop up over and over again which asks me if I want to open the form. One possible solution is downgrading to Safari 3, but that is not proven to work. I thought maybe I could get the FDF to open in FireFox, but changing the default browser does not affect Reader, it still attempts to open the FDF in Safari (strange). So, does anyone know of a way to open this form? Thanks -Corey

• jQuery - color cycle animation with hsv colorspace?

  - by Sgt. Floyd Pepper

  Hi there, I am working on a project, which I need a special body-background for. The background-color should cycle through the color spectrum like a mood light. So I found this: http://buildinternet.com/2009/09/its-a-rainbow-color-changing-text-and-backgrounds/ "But" this snippet is working with the RGB colorspace which has some very light and dark colors in it. Getting just bright colors will only work with the HSV colorspace (e.g. having S and V static at 100 and letting H cycle). I don’t know how to convert and in fact how to pimp this snippet for my needs. Does anyone has an idea?? Thanks in advance. Best, Floyd

• /users/tags should contain scores

  - by Sean Patrick Floyd

  I am implementing some simple JavaScript/bookmarklet based apps that show some reputation info, including the score in the User's top tags (roughly based on this previous bookmarklet of mine). Now I can get a user's top tags (using the API), and I can also get the per-tag score if the user is logged in, by dynamically parsing the tag's top users page. But it costs me one AJAX request per tag and I have to download 10+k to extract a single numeric value. It would save a lot of traffic if the tags in <api>/users/<userid>/tags had a score field. The data seems to be there, after all the top users pages use it, so it would just be a question of exposing the data. Suggested structure: "tags": [ { "name": { "description": "name of the tag", "values": "string", "optional": false, "suggested_buffer_size": 25 }, "score": { "description": "tag score, sum of up votes for answers on non-wiki questions", "values": "32-bit signed integer", "optional": false }, "count": { "description": "tag count, exact meaning depends on context", "values": "32-bit signed integer", "optional": false }, "restricted_to": { "description": "user types that can make use of this tag, lack of this field indicates it is useable by all", "values": "one of anonymous, unregistered, registered, or moderator", "optional": true }, "fulfills_required": { "description": "indicates whether this tag is one of those that is required to be on a post", "values": "boolean", "optional": false }, "user_id": { "description": "user associated with this tag, depends on context", "values": "32-bit signed integer", "optional": true } } ]

• Craftsmanship Tour: Day 2 Obtiva

  - by Liam McLennan

  I like Chicago. It is a great city for travellers. From the moment I got off the plane at O’Hare everything was easy. I took the train to ‘the Loop’ and walked around the corner to my hotel, Hotel Blake on Dearborn St. Sadly, the elevated train lines in downtown Chicago remind me of ‘Shall We Dance’. Hotel Blake is excellent (except for the breakfast) and the concierge directed me to a pizza place called Lou Malnati's for Chicago style deep-dish pizza. Lou Malnati’s would be a great place to go with a group of friends. I felt strange dining there by myself, but the food and service were excellent. As usual in the United States the portion was so large that I could not finish it, but oh how I tried. Dave Hoover, who invited me to Obtiva for the day, had asked me to arrive at 9:45am. I was up early and had some time to kill so I stopped at the Willis Tower, since it was on my way to the office. Willis Tower is 1,451 feet (442 m) tall and has an observation deck at the top. Around the observation deck are a set of acrylic boxes, protruding from the side of the building. Brave soles can walk out on the perspex and look between their feet all the way down to the street. It is unnerving. Obtiva is a progressive, craftsmanship-focused software development company in downtown Chicago. Dave even wrote a book, Apprenticeship Patterns, that provides a catalogue of patterns to assist aspiring software craftsmen to achieve their goals. I spent the morning working in Obtiva’s software studio, an open xp-style office that houses Obtiva’s in-house development team. For lunch Dave Hoover, Corey Haines, Cory Foy and I went to a local Greek restaurant (not Dancing Zorbas). Dave, Corey and Cory are three smart and motivated guys and I found their ideas enlightening. It was especially great to chat with Corey Haines since he was the inspiration for my craftsmanship tour in the first place. After lunch I recorded a brief interview with Dave. Unfortunately, the battery in my camera went flat so I missed recording some interesting stuff. Interview with Dave Hoover In the evening Obtiva hosted an rspec hackfest with David Chelimsky and others. This was an excellent opportunity to be around some of the very best ruby programmers. At 10pm I went back to my hotel to get some rest before my train north the next morning.

• Does Windows Azure support the Application Warm-Up module or something similar?

  - by Corey O'Brien

  We have a Web Role that we are hosting in Windows Azure that uses an old ASMX based Web Reference to contact an external system. The Web Reference proxy code is big enough that instantiating it the first time has a significant cost. We'd like to be able to have this run when the Web Role starts instead of on the first request. I know IIS 7.5 has an Application Warm-Up module that would allow us to achieve this, but I'm having trouble figuring out if something similar exists with hosting on Windows Azure. Thanks, Corey

• How can I keep a WPF Image from blocking if the ImageSource references an unreachable Url?

  - by Corey O'Brien

  I'm writing a WPF application and trying to bind an image to my view model with the following XAML: <Image Source="{Binding Author.IconUrl, IsAsync=True}" /> The problem is that the image URLs are defined by users and can often refer to images hosted on intranet web servers. When the WPF application is run remotely, it locks up while trying to resolve the images that are now unreachable. I thought the "IsAsync" binding property would cause the load to happen in the background, but it appears that the DNS resolution may still happen in the main thread? What can I do to keep my app from locking, even if the images are unreachable? Thanks, Corey

• NHibernate Legacy Database Mappings Impossible?

  - by Corey Coogan

  I'm hoping someone can help me with mapping a legacy database. The problem I'm describing here has plagued others, yet I was unable to find a real good solution around the web. DISCLAIMER: this is a legacy DB. I have no control over the composite keys. They suck and can't be changed no matter much you tell me they suck. I have 2 tables, both with composite keys. One of the keys from one table is used as part of the key to get a collection from the other table. In short, the keys don't fully match between the table. ClassB is used everywhere I would like to avoid adding properties for the sake of this mapping if possible. public class ClassA { //[PK] public string SsoUid; //[PK] public string PolicyNumber; public IList<ClassB> Others; //more properties.... } public class ClassB { //[PK] public string PolicyNumber; //[PK] public string PolicyDateTime; //more properties } I want to get an instance of ClassA and get all ClassB rows that match PolicyNumber. I am trying to get something going with a one-to-many, but I realize that this may technically be a many-to-many that I am just treating as one-to-many. I've tried using an association class but didn't get far enough to see if it works. I'm new to these more complex mappings and am looking for advice. I'm open to pretty much any ideas. Thanks, Corey

• Solutions for working with multiple branches in ASP.Net

  - by Corey McKinnon

  At work, we are often working on multiple branches of our product at one time. For example, right now, we have a maintenance branch, a branch with code just going to QA, and a branch for a new major initiative, that won't be merged for some time now. Our web project is set up to use IIS, so every time we switch to a different branch, we have to go in to IIS Admin and change the path on the virtual directory, then reset IIS, and sometimes even restart Visual Studio, to avoid getting build errors. Is there any way to simplify this, other than not having our web project set up as a virtual directory? I'm not sure we want to make that change at this point. What do you do to make this easier, assuming you do this? Corey @RedWolves, virtual machines would definitely work, but I'm not sure it would be any simpler, especially for some of the other developers on my team, which is partly why I'm looking for more simplicity. @Dan, we're not able to change source control providers, unfortunately. @pix0r, that's something I'll try when I get back to work. Thanks for the suggestion. @Haacked, I'll have to give that a try too, but I think we have some issues with why that won't work (I can't remember exactly why right now; this application was originally written in .Net 1.1, pre-Cassini, and I can't remember if we tried it when we upgraded to 2.0 or not). Thanks all for the responses so far.

• MDT 2012 Image Capture

  - by floyd

  I am using MDT 2012 Update 1. Attempting to Deploy 2012 DC to a VM, run windows updates, and then sysprep/capture that image. This is the same task sequence process I have used for Windows 7 / 2008 R2 and it works fine. However, for 2012 DC it deploys the image, starts running/installing updates and then on reboot it goes to a "Choose an option" screen if I choose "Exit and continue to Windows Server 2012" it reboots and goes back to same screen. Any ideas?

• Top Down RPG Movement w/ Correction?

  - by Corey Ogburn

  I would hope that we have all played Zelda: A Link to the Past, please correct me if I'm wrong, but I want to emulate that kind of 2D, top-down character movement with a touch of correction. It has been done in other games, but I feel this reference would be the easiest to relate to. More specifically the kind of movement and correction I'm talking about is: Floating movement not restricted to tile based movement like Pokemon and other games where one tap of the movement pad moves you one square in that cardinal direction. This floating movement should be able to achieve diagonal motion. If you're walking West and you come to a wall that is diagonal in a North East/South West fashion, you are corrected into a South West movement even if you continue holding left (West) on the controller. This should work for both diagonals correcting in both directions. If you're a few pixels off from walking squarely into a door or hallway, you are corrected into walking through the hall or down the hallway, i.e. bumping into the corner causes you to be pushed into the hall/door. I've hunted for efficient ways to achieve this and have had no luck. To be clear I'm talking about the human character's movement, not an NPC's movement. Are their resources available on this kind of movement? Equations or algorithms explained on a wiki or something? I'm using the XNA Framework, is there anything in it to help with this?

• Where can I find video resources of people programming?

  - by Corey

  This might be a strange question. I'm looking for videos of people actively coding something while explaining it. However, I don't want is a beginner video that delves into what variables and objects are. Nick Gravelyn's tile engine tutorial is a great example of what I'm looking for. (He actually used to host the full, unbroken video files in his site's archive, but I guess he took them down...) I tend to learn best by "action" examples; it's difficult for me to learn by reading through documentation and text tutorials, but if I see somebody actively doing a task, I can immediately register it and apply it myself. I'm hard-of-hearing, so I would really prefer that if the video has a lot of talking, it have captioning or subtitling of some sort, or at the very least, a transcript. The tile engine videos did not have captions, but the code he was writing was very self-documenting, so I understood it for the most part. I've gone through most of the relevant GoogleDevelopers and GoogleTechTalks videos on Youtube, so those need not apply. Are there any resources out there, or even websites dedicated to this kind of thing?

• Java Slick2d - How to translate mouse coordinates to world coordinates

  - by Corey

  I am translating in my main class render. How do I get the mouse position where my mouse actually is after I scroll the screen public void render(GameContainer gc, Graphics g) throws SlickException { float centerX = 800/2; float centerY = 600/2; g.translate(centerX, centerY); g.translate(-player.playerX, -player.playerY); gen.render(g); player.render(g); } playerX = 800 /2 - sprite.getWidth(); playerY = 600 /2 - sprite.getHeight(); Image to help with explanation I tried implementing a camera but it seems no matter what I can't get the mouse position. I was told to do this worldX = mouseX + camX; but it didn't work the mouse was still off. Here is my Camera class if that helps: public class Camera { public float camX; public float camY; Player player; public void init() { player = new Player(); } public void update(GameContainer gc, int delta) { Input input = gc.getInput(); if(input.isKeyDown(Input.KEY_W)) { camY -= player.speed * delta; } if(input.isKeyDown(Input.KEY_S)) { camY += player.speed * delta; } if(input.isKeyDown(Input.KEY_A)) { camX -= player.speed * delta; } if(input.isKeyDown(Input.KEY_D)) { camX += player.speed * delta; } } Code used to convert mouse worldX = (int) (mouseX + cam.camX); worldY = (int) (mouseY + cam.camY);

• CSS practices: negative positioning

  - by Corey

  I'm somewhat of a novice to CSS. Anyway, I noticed that an extremely common method used in CSS is to have negative or off-screen positioning, whether it be to hide text or preload images or what have you. Even on SE sites, like StackOverflow and this website, have #hlogo a { text-indent: -999999em } set in their CSS. So I guess I have a few questions. is this valid CSS? or is it just a "hack"? are there downsides to doing things this way? why is this so common? aren't there better ways to hide content?

• How do you differentiate between "box," "machine," "computer" and whatever else?

  - by Corey

  There seems to be a few terms for referring to a computer, especially in the tech world. Different terms seem to be used based on technical expertise. When talking with people with some technical knowledge, I'll refer to it as a machine. When talking to non-technical people (family, friends) I'll call it a computer. On the rare occasion I'm talking about servers, I might call it a box, but even then I'll probably still call it a machine. Is that just me, or do there exist rules already for what to call a computer?

• Tile engine Texture not updating when numbers in array change

  - by Corey

  I draw my map from a txt file. I am using java with slick2d library. When I print the array the number changes in the array, but the texture doesn't change. public class Tiles { public Image[] tiles = new Image[5]; public int[][] map = new int[64][64]; public Image grass, dirt, fence, mound; private SpriteSheet tileSheet; public int tileWidth = 32; public int tileHeight = 32; public void init() throws IOException, SlickException { tileSheet = new SpriteSheet("assets/tiles.png", tileWidth, tileHeight); grass = tileSheet.getSprite(0, 0); dirt = tileSheet.getSprite(7, 7); fence = tileSheet.getSprite(2, 0); mound = tileSheet.getSprite(2, 6); tiles[0] = grass; tiles[1] = dirt; tiles[2] = fence; tiles[3] = mound; int x=0, y=0; BufferedReader in = new BufferedReader(new FileReader("assets/map.dat")); String line; while ((line = in.readLine()) != null) { String[] values = line.split(","); x = 0; for (String str : values) { int str_int = Integer.parseInt(str); map[x][y]=str_int; //System.out.print(map[x][y] + " "); x++; } //System.out.println(""); y++; } in.close(); } public void update(GameContainer gc) { } public void render(GameContainer gc) { for(int y = 0; y < map.length; y++) { for(int x = 0; x < map[0].length; x ++) { int textureIndex = map[x][y]; Image texture = tiles[textureIndex]; texture.draw(x*tileWidth,y*tileHeight); } } } } Mouse Picking Where I change the number in the array Input input = gc.getInput(); gc.getInput().setOffset(cameraX-400, cameraY-300); float mouseX = input.getMouseX(); float mouseY = input.getMouseY(); double mousetileX = Math.floor((double)mouseX/tiles.tileWidth); double mousetileY = Math.floor((double)mouseY/tiles.tileHeight); double playertileX = Math.floor(playerX/tiles.tileWidth); double playertileY = Math.floor(playerY/tiles.tileHeight); double lengthX = Math.abs((float)playertileX - mousetileX); double lengthY = Math.abs((float)playertileY - mousetileY); double distance = Math.sqrt((lengthX*lengthX)+(lengthY*lengthY)); if(input.isMousePressed(Input.MOUSE_LEFT_BUTTON) && distance < 4) { System.out.println("Clicked"); if(tiles.map[(int)mousetileX][(int)mousetileY] == 1) { tiles.map[(int)mousetileX][(int)mousetileY] = 0; } } I never ask a question until I have tried to figure it out myself. I have been stuck with this problem for two weeks. It's not like this site is made for asking questions or anything. So if you actually try to help me instead of telling me to use a debugger thank you. You either get told you have too much or too little code. Nothing is never enough for the people on here it's as bad as something like reddit. Idk what is wrong all my textures work when I render them it just doesn't update when the number in the array changes. I am obviously debugging when I say that I was printing the array and the number is changing like it should, so it's not a problem with my mouse picking code. It is a problem with my textures, but I don't know what because they all render correctly. That is why I need help.
