WebNov 8, 2024 · Uninformed or blind search strategies are those which use only the components we provide in the problem definition. So, they differentiate only between goal and non-goal states and can’t inspect the inner structure of a state to estimate how close it is to the goal. For example, let’s say that we’re solving an 8-puzzle. WebA* Search.

"WebThe main drawback of pure heuristic search is that since it ignores the cost of the path so far to node n, it does not find optimal solutions. Breadth-first search, uniform-cost search, and pure heuristic search are all special cases of a more general algorithm called best-first search. In each cycle of a best-first search, the node that is ... " - Breadth first heuristic search
