In other words, the graph must be "bipartite". Bipartite graphs work so well, in fact, that they will often terminate with a maximum matching after a greedy match. In some cases, however, the greedy match will require augmentation. dictionary\u0027s 9b citydwellers

"WebThe greedy method, an iterative strategy that seeks for an optimum solution by constantly selecting the best choice in the current state, is how the greedy algorithm operates. The Greedy Algorithm also employs a graph-search strategy, an iterative method that looks for the best answer by taking the edges and nodes of the graph into account. 6. " - Greedy match algorithm
