对于“人工智能导论”中的一项作业,我需要解决以下问题:
Let f(n) = c1*g(n) + c2*h(n) be an evaluation function, where c1,c2 be constants.
1. Define c1,c2,h(.),g(.) such that A* with this evaluation function is bfs.
2. Define c1,c2,h(.),g(.) such that A* with this evaluation function is dfs.
对于BFS,我有以下想法:假设g(n)是从开始节点到当前节点的成本,h(
我正在做一个在线的人工智能课程作业。作为任务的一部分,我必须在python中实现A*搜索。我的代码:
def aStarSearch(problem, heuristic=nullHeuristic):
"""Search the node that has the lowest combined cost and heuristic first."""
"*** YOUR CODE HERE ***"
fringe = util.PriorityQueue()
visited = {} # Visited no
