Chapter 3, Problem 28E
Program Plan Intro
Suboptimal solution:
- Suboptimal heuristic search
algorithms such as weighted A* and greedy best-first search are widely use to solve problems for which guaranteed optimal solutions are too expensive to obtain. - To guide their search, these algorithms rely on a heuristic function.
- These algorithms are used because, when constructing the heuristics, the optimal search can fail when considering the suboptimal search.
Explanation of Solution
Proof:
- As given in the problem, suppose
- Consider any node n on a path to an optimal goal. Here,
