feat: add 1 Tier 1a/1b corrected reduction rules (#770)#915
Conversation
Implement the classic NAE-3-SAT → MaxCut reduction via variable gadgets (complementary vertex pairs with weight M = 2m+1) and clause triangles. Each NAE-satisfied clause contributes exactly 2 cut edges, giving a tight threshold of nM + 2m. Includes reduction rule, unit tests (7 tests), canonical example_db entry, paper entry, and updated dominated-rules allow-list. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
