Search strategies
n A search strategy is defined by picking the order of node
expansion
n Strategies are evaluated along the following dimensions:
n completeness: does it always find a solution if one exists?
n time complexity: number of nodes generated
n space complexity: maximum number of nodes in memory
n optimality: does it always find a least-cost solution?
n Time and space complexity are measured in terms of
n b: maximum branching factor of the search tree
n d: depth of the least-cost solution
n m: maximum depth of the state space (may be )
