WebThe Python code to implement Prim’s algorithm is shown below. Prim’s algorithm is similar to Dijkstra’s algorithm in that they both use a priority queue to select the next vertex to add to the growing graph. from collections import defaultdict import heapq def create_spanning_tree(graph, starting_vertex): mst = defaultdict(set) visited ... Web• Best-first search is agreedy method. Greedy methods maximize short-term advantage without worrying about long-term consequences. COMP-424, Lecture 3 - January 14, 2013 5 Fixing greedy search • The problem with best-first search is that it is too greedy: it does not take into account the cost so far! • Letgbe thecost of the path so far
