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.
