Sep 23, 2024 · The 8-puzzle problem is a classic artificial intelligence problem that challenges you to move tiles on a 3x3 board to achieve a goal state. May 21, 2021 · Another alternative solution, where: states are represented as terms, and; iterative deepening search is controled through the use of predicate length/2. In this blog post, we'll examine how to solve this problem using Depth-First Search (DFS) and correct an issue commonly encountered during implementation. I just want some clean function which will efficiently generate states and there will be a Explored array which will assure that there is no redundant state. 101x Artificial Intelligence (AI).
