Abstract
SSLD improves the DSATUR heuristic for the Graph Coloring Problem by preprocessing a first good color class using Semidefinite Programming.
Reality Card
Core Claim
SSLD matches or beats DSATUR in almost every case across over 1600 benchmark instances, demonstrating the effectiveness of SDP-guided preprocessing.
Method / Result
SSLD is roughly 195 times slower than DSATUR but outperforms the naive GISD baseline.
Limitations
The significant runtime cost of SSLD compared to DSATUR may limit its practical application.
