= Unsolved problems in graph theory
{wiki=Category:Unsolved_problems_in_graph_theory}
Graph theory is a rich area of mathematics with many interesting unsolved problems. Here are some notable ones: 1. **Graph Isomorphism Problem**: This problem asks whether two finite graphs are isomorphic, meaning they have the same structure regardless of the labels of their vertices. While there are polynomial-time algorithms for certain classes of graphs, a general polynomial-time solution for all graphs remains elusive.
