This always finds a goal state nearest to the root. I am trying to solve the 8 puzzle game. For path finding methods, BFS is the best algorithm, but what if you want to fill all the gaps (not rocks), in the matrix, aka visiting all cells, while doing this with the least amount of cell visited (visiting old, or already visited cells, counts as a new visits), or the least cell traveled. BFS takes too long to solve a 4x4 puzzle so we need a faster algorithm. How can we solve a 4x4 puzzle in a reasonable amount of time?

Jun 18, 2013 · as for pretty much any problem, one "easy/simple" method to solve such a problem is to represent puzzle states as a graph, and use a graph search / path finding algorithm (DFS,BFS,Dijkstra,A*,etc. A simple breadth first search (BFS) would take too much time. This visualization is rich with a lot of DFS and BFS variants (all run in O(V+E)) such as: Topological Sort algorithm (both DFS and BFS/Kahn's algorithm version),Bipartite Graph Checker algorithm (both DFS and BFS version),Cut Implementation of some heuristic algorithms to solve sliding puzzle supports (in theory) any A by B sliding puzzle. DFS will ignore many moves at each stage. Solve Myself Edit Start See full list on codeproject. This option works in the browser, in it you need to specify a regular picture, the program itself will cut the picture into squares and mix them. Idea: BFS explores all neighbor nodes at the present depth before moving on to nodes at the next depth level.
