Question - Search
- View SourceSome quz about search:
1> A* algorithm
When I make a program to slove a graph problem, I use graph search
so that I must do the thing to cheak if a node has been visited. To
this thing, I could use hash table to check, but whether a better
approach to do it?
2> IDS algorithm
The book said that IDS will be bether than the BFS because that IDS
will bounds less nodes than BFS. But in fact the IDS run slower than
BFS when I use the algorithms to slove a same search problem, why?
btw, I want to know that if Peking University in China use this book to
teach the class of AI?
