Graph of Thoughts overview

Explores the solution space as a directed graph with branching, merging, and backtracking. Builds a graph of thought nodes, branches at decision points to generate alternative approaches, evaluates each branch independently, prunes low-scoring branches, allows merging when branches converge to similar solutions, supports backtracking to explore alternative paths, and navigates the graph to find the optimal solution path. Extends tree-of-thoughts with merge operations.
