Created refined investigation script for Erdős–Gyárfás conjecture
where previous test found no power-of-two cycles (conjecture holds: False).
Refinements:
- Regular graph construction (all vertices same degree)
- Exhaustive DFS cycle detection
- More samples per n (5 instead of 3)
- Extended n values [8, 10, 12, 14, 16]
Goal: Determine if previous negative result was due to random graph construction
or if regular graphs with exhaustive cycle detection find power-of-two cycles.
Script created: investigate_erdos_gyarfas_refined.py
Execution canceled by user - awaiting further instructions.
