Webb• A problem space consists of states and operators • States – specify values of all attributes of interest in the world • Operators – change one state into another – … Webb4 juli 2024 · State-space representation. In a state-space representation method, each state of the problem is represented by a node of a graph or tree structure. In this case, the problem is translated as a search problem to determine the goal under specific operators and restrains. In this post, I will introduce Traveling Salesman Problem (TSP) as an ...
