shortest-path

Hello, i want to ask if there is any way to generate the shortest path from node A to node B without generating the shortest paths to all the other nodes (stop when node B is in the examined set) with A-star in QuickGraph.

I want to plug QuickGraph into a game and thus generating all the paths is not allowed from the time limitations the environment imposes.

Any other suggestions to solve my problem in C# are welcome

Thanks in advance, Xtapodi

Hi, In QuickGraph - is there algorithm for find all parents (up to root vertex's) of a set of vertex's. In other words all vertex's which have somewhere under them (on the way to the leaf nodes) one or more of the vertexs input.
