  • Permutations of Varying Size

    - by waiwai933
    I'm trying to write a function in PHP that gets all permutations of all possible sizes. I think an example would be the best way to start off: $my_array = array(1,1,2,3); Possible permutations of varying size: 1 1 // * See Note 2 3 1,1 1,2 1,3 // And so forth, for all the sets of size 2 1,1,2 1,1,3 1,2,1 // And so forth, for all the sets of size 3 1,1,2,3 1,1,3,2 // And so forth, for all the sets of size 4 Note: I don't care if there's a duplicate or not. For the purposes of this example, all future duplicates have been omitted. What I have so far in PHP: function getPermutations($my_array){ $permutation_length = 1; $keep_going = true; while($keep_going){ while($there_are_still_permutations_with_this_length){ // Generate the next permutation and return it into an array // Of course, the actual important part of the code is what I'm having trouble with. } $permutation_length++; if($permutation_length>count($my_array)){ $keep_going = false; } else{ $keep_going = true; } } return $return_array; } The closest thing I can think of is shuffling the array, picking the first n elements, seeing if it's already in the results array, and if it's not, add it in, and then stop when there are mathematically no more possible permutations for that length. But it's ugly and resource-inefficient. Any pseudocode algorithms would be greatly appreciated. Also, for super-duper (worthless) bonus points, is there a way to get just 1 permutation with the function but make it so that it doesn't have to recalculate all previous permutations to get the next? For example, I pass it a parameter 3, which means it's already done 3 permutations, and it just generates number 4 without redoing the previous 3? (Passing it the parameter is not necessary, it could keep track in a global or static). The reason I ask this is because as the array grows, so does the number of possible combinations. Suffice it to say that one small data set with only a dozen elements grows quickly into the trillions of possible combinations and I don't want to task PHP with holding trillions of permutations in its memory at once.

  • Unfamiliar notation found in a computer science book

    - by cornjuliox
    I'm reading through this computer science book and throughout the book I see a number of things written like so: and then there's this: and then this: What kind of notation is the "Boolean Expression" in example 1 written in? I've never seen anything like it before and I'm tempted to assume that whoever wrote and/or scanned this book in fell asleep at the keyboard, and assuming that it's even valid, what about the 3rd example? I'm pretty sure that's not C++ or VB.NET they're showing there.

  • ASP.NET based object inspector

    - by Richard Edwards
    I'm currently writing some code that uses Flee to evaluate a number of rules and I'd like to include an ASP.NET based object inspector in the configuration screen so users can inspect the values of objects that are made available. I've put together a fairly basic routine to recurse an objects properties and spit it out but before I go and write something more polished, I'm wondering if anyone knows of a component that provides this functionality.

  • Trying to retrieve the contents of UITableView cell on selection by user.

    - by chubsta
    Hi, this is my first post here and as i am very new (2 weeks in...) to iPhone (or any!) development i am a little unsure as to how much detail is needed or relevant, so please forgive me if I dont provide enough to be useful at this stage... Anyway, on to my problem - I have set up a UITableView-based app, which has a .plist for holding the data. The .plist has a dictionary as its root, followed by a number of Arrays, each containing the data-strings that display in the table. Everything is working fine until the point where i select a row. I have set it up so i get an alert with the results of the button press and it is here that i want to see the contents of the cell being produced. Instead of the expected string eg. "data line 1", all i get is the number of the row within the section. I have gone backwards and forwards but dont seem to be getting anywhere although i am sure it is something simple. The code compiles fine, with no warnings or errors, and if i can just get the string of the selected cell i will be well on my way, so any help appreciated. I know that I need to do more following the 'NSUInteger row = [indexPath row]; part but thats where my mind dries up... here is the relevant 'selection' section, if i need to post more code please let me know, and i really appreciate any help with this...(please forgive my 'alert' message, i was just happy at that point that i get SOMETHING back from the row selection!) (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { [tableView deselectRowAtIndexPath:indexPath animated:YES]; NSUInteger row = [indexPath row]; NSString *message = [[NSString alloc] initWithFormat: @"You selected Cell %d from this Section, "@"which is a very good choice indeed!" @"Unfortunately I can't work out how to get the info out of the cell so it's not much use at the moment!" @"Still, this is a good chance to see how much space I have in an alert box!", row]; UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"My God! It works..." message:message delegate:nil cancelButtonTitle:@"You are awesome Karl!!" otherButtonTitles:nil]; [alert show]; [message release]; [alert release]; }

  • Did anyone create the Java Code Formatter Profile for Eclipse IDE that conforms to the Android Code

    - by yvolk
    Android Code Style Guide defines "Android Code Style Rules". To conform to these rules one have to change quite a number of settings of the Java Code Formatter (Window-Preferences-Java-Formatter) default profile (in Eclipse IDE). Did anyone managed to configure the formatter to follow the "Android Code Style Rules" already? If yes, please export the Formatter profile and publish to be used by community. PS: I've tried to do this myself but I've found that there are too many formatter options available, and most of them are not mentioned in the Code Style Guide :-(

  • Looking for Java libraries to create a report editor

    - by Julian
    I have to develop a specialised report editor in Java. The user will get a number of fields that can be layed out on a page plus some graphical elements. The resulting report design needs to be serialized into already defined database tables. Is there any software library that will help to achieve this without reinventing the wheel? I have come across Eclipse GEF and Zest, but I am not sure if this really meets my problem.

  • Debugging stored procedure in SQL Server 2008 Management Studio

    - by larryq
    Hi everyone, I have a stored proc I'd like to debug in the SQL Server 2008 management studio. I see a number of tutorials about doing this, but the ones I've seen don't have any input parameters going into the SP. My SP has several, and an output parameter as well. Could someone show me how to do debug a stored procedure with parameters in SQL 2008? Thanks very much.

  • Textarea that can do syntax highlighting on the fly?

    - by Pekka
    I am storing a number of HTML blocks inside a CMS for reasons of easier maintenance. They are represented by TEXTAREAs. Does anybody know a JavaScript Widget of some sort that can do syntax highlighting for HTML within a Textarea or similar, while still staying a plain text editor (no WYSIWYG or advanced functions)?

  • Constraint Satisfaction Problem

    - by Carl Smotricz
    I'm struggling my way through Artificial Intelligence: A Modern Approach in order to alleviate my natural stupidity. In trying to solve some of the exercises, I've come up against the "Who Owns the Zebra" problem, Exercise 5.13 in Chapter 5. This has been a topic here on SO but the responses mostly addressed the question "how would you solve this if you had a free choice of problem solving software available?" I accept that Prolog is a very appropriate programming language for this kind of problem, and there are some fine packages available, e.g. in Python as shown by the top-ranked answer and also standalone. Alas, none of this is helping me "tough it out" in a way as outlined by the book. The book appears to suggest building a set of dual or perhaps global constraints, and then implementing some of the algorithms mentioned to find a solution. I'm having a lot of trouble coming up with a set of constraints suitable for modelling the problem. I'm studying this on my own so I don't have access to a professor or TA to get me over the hump - this is where I'm asking for your help. I see little similarity to the examples in the chapter. I was eager to build dual constraints and started out by creating (the logical equivalent of) 25 variables: nationality1, nationality2, nationality3, ... nationality5, pet1, pet2, pet3, ... pet5, drink1 ... drink5 and so on, where the number was indicative of the house's position. This is fine for building the unary constraints, e.g. The Norwegian lives in the first house: nationality1 = { :norway }. But most of the constraints are a combination of two such variables through a common house number, e.g. The Swede has a dog: nationality[n] = { :sweden } AND pet[n] = { :dog } where n can range from 1 to 5, obviously. Or stated another way: nationality1 = { :sweden } AND pet1 = { :dog } XOR nationality2 = { :sweden } AND pet2 = { :dog } XOR nationality3 = { :sweden } AND pet3 = { :dog } XOR nationality4 = { :sweden } AND pet4 = { :dog } XOR nationality5 = { :sweden } AND pet5 = { :dog } ...which has a decidedly different feel to it than the "list of tuples" advocated by the book: ( X1, X2, X3 = { val1, val2, val3 }, { val4, val5, val6 }, ... ) I'm not looking for a solution per se; I'm looking for a start on how to model this problem in a way that's compatible with the book's approach. Any help appreciated.

  • preg_replace only part of match

    - by Tony Vipros
    Hi, I'm using preg_replace to create urls for modrewrite based paging links. I use: $nextURL = preg_replace('%/([\d]+)/%','/'.($pageNumber+1).'/',$currentURL); which works fine, however I was wondering if there is a better way without having to include the '/' in the replacement parameter. I need to match the number as being between two / as the URLs can sometimes contain numbers other than the page part. These numbers are never only numbers however, so have /[\d]+/ stops them from getting replaced.

  • ASP.NET, JQuery - Sharing regular expressions

    - by Steve
    If you have a fair number of regular expressions used by both client (javascript) and server side code (C#, vb.net) and want to store them in one place to avoid duplication, where do you store them? I could use registerscript and write out the regex as strings, but just wondering if there is something more elegant.

  • Handling connection errors in a MDB

    - by Rafa de Castro
    Is it possible to manage connection timeouts or errors in a MessageDrivenBean? You can make the factory to retry connecting a certain number of times but... is it possible to make some actions each time that a reconnection retrial is neccesary? Is it possible to register an ExceptionListener into the MessageDrivenBean's connection somehow? Thanks a lot.
