As the algorithm may not terminate and go on infinitely on one path. Hence, a solution to this issue is to choose a cut-off depth. If the ideal cut-off is d, and if the chosen cut-off is lesser than d, then this algorithm may fail. If the chosen cut-off is more than d, then execution … Read more
It consumes a lot of memory space. As each level of nodes is saved for creating the next one. Its complexity depends on the number of nodes. It can check duplicate nodes. For an interview question about the disadvantages of the Breadth-First Search (BFS) algorithm, you could mention several points: Memory Usage: One major disadvantage … Read more
There can be multiple long paths with the cost ≤ C*. Uniform Cost search must explore them all. The Uniform Cost Search (UCS) algorithm, while effective in finding the lowest-cost path in a graph, does have some disadvantages: Space Complexity: UCS explores all possible paths to find the lowest-cost path. In scenarios where the graph … Read more
To perform this search we need to follow steps. As it performs the DFS starting to level 1, starts and then executes a complete depth-first search to level 2. Moreover, we have to continue searching process till we find the solution. We have to generate nodes till single nodes are created. Also, it saves only … Read more
Basically, it performs sorting in increasing the cost of the path to a node. Also, always expands the least cost node. Although, it is identical to Breadth-First search if each transition has the same cost. It explores paths in the increasing order of cost. The Uniform Cost Search (UCS) algorithm is a variant of Dijkstra’s … Read more
