It starts at the tree’s root or graph and searches/visits all nodes at the …
WebNov 21, 2024 · Breath-first search only cares about the number of moves needed to reach a state, not the total cost of getting there, so if some states are cheaper on a per-move basis, it's not optimal. Ok, back to the question: basically, the statement you reference applies to Breadth-first search run on a GRAPH-SEARCH problem.
Webo breadth-first search is not optimal until all actions have the same cost (because it always finds the shallowest node first) Space complexity and Time complexity: o Consider a state space where each node as a branching factor b, the root of the tree generates b nodes, each of which generates b nodes yielding b 2 each of these generates b 3 ...
