Heuristic 3 - This heuristic adds 2 for every block that is not currently directly on top of the block on which it has to be in the goal state or if there is such a block somewhere below it (in the same pile). If Block A in the goal state is supposed to be on top of Block B and under Block C and in the current state it is neither on top of B or under C, then we add 2 to the heuristic. It calculates the difference between the current state and the goal state, but looks at the details of each block. Heuristic 2 - this heuristic is similar to Heuristic 1. ![]() We do not count a block if it is currently in the arm of the crane. Heuristics description: Heuristic 1 - this heuristic calculates the number of blocks that are currently not in the correct 'position'. We used six different heuristics to solve the problem using A*. These include DFS, BFS, UCS, A* and simulated annealing. We used a number of algorithms to solve the problem. ![]() The blocks world is a NP-hard problem and we wanted to find smart solution to solve it. ![]() The program was created by Terry Winograd and is a limited-domain natural-language system that can understand typed commands and move blocks around on a surface. The blocks world is one of the most famous planning domains in artificial intelligence. ![]()
