A Forced-Structure Reduction and Verifiable Bounds for Conway's 99-Graph
TL;DR
A systematic AI-driven investigation into Conway's 99-graph problem reveals that no circulant graph can meet more than 68% of the required constraints. The study establishes a forced-structure reduction leading to a 12-regular graph on 84 vertices, contributing to the understanding of graph existence limits.
✦ Why It Matters
Consider exploring the implications of forced-structure reductions in your own graph theory research.
Key Takeaways
- Investigate the implications of graph constraints in your projects.
- Explore forced-structure reductions for complex graph problems.
- Utilize CP-SAT for encoding and validating graph structures.
- Consider the significance of automorphism orbits in graph theory.
How It Works
The research employs a forced-structure reduction technique, where specific parameters (lambda and mu) are manipulated to simplify the graph's neighborhood structure. This leads to a transformation into a 12-regular graph on 84 vertices, making it easier to analyze and validate against known graph types.
