Note: Hamiltonian is NP-complete, so focus on small graphs and verification.\n\n### Tasks\n- [ ] Implement Eulerian path/circuit existence check (degree conditions)\n- [ ] Implement Eulerian path/circuit finder (Fleury's or Hierholzer's algorithm)\n- [ ] Implement Hamiltonian path/circuit verification (check if given path is valid)\n- [ ] Add Hamiltonian existence check with timeout for small graphs\n- [ ] Support both directed and undirected graphs for Eulerian\n- [ ] Write comprehensive unit tests\n- [ ] Add clear feedback for why Eulerian path doesn't exist\n\n### Acceptance Criteria\n- Eulerian algorithms work correctly for all graph types\n- Hamiltonian verification works for any graph size\n- Hamiltonian existence check works for graphs up to 10 nodes\n- Clear feedback when paths don't exist\n- Unit tests cover all edge cases","author":{"url":"https://github.com/JohnnyWan1123","@type":"Person","name":"JohnnyWan1123"},"datePublished":"2026-01-29T19:54:49.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":0},"url":"https://github.com/5/graph-eval/issues/5"}
