[algogeeks] Need Help on Hopcroft-Karp Algorithm

2006-08-21 Thread phoenixinter
Hi guys I'm recently trying to study the Hopcroft-Karp Algorithm that can compute the maximum matching of a bipartite graph in O(sqrt(n)*m) complexity. However I find it not so easy to understand. Can anybody help me explaining how the algorithm works or give me a working implementation of HK

[algogeeks] Minesweeper Algoritm Contest

2006-08-21 Thread JeffCameron
Hello algorithm enthusiasts! I recently became interested in Minesweeper-solving algorithms, and would like to propose a competition. We will each write a C/C++/Java function that takes a minesweeper board, along with its width and height, and then returns which square to click next. For

Hi Jeff, Glad to hear you say on average in judging the algorithm's, because minesweeper is all about probablities, imo. Even the best algo could be foiled by an unlucky guess. If you have an algo for this probabibility calculation, until you find a square with 100% safety, (or the safest

RE: If you have an algo for this probabibility calculation, until you find a square with 100% safety, (or the safest square on the board), you have minesweeper solved as well as it can be. In fact, this is not true. Simply selecting the square that minimizes the probability of uncovering a
