VERA Brief

AI-generated. Grounded in the article and its cited sources.

Researchers have developed SSLD, a new preprocessing technique for the DSATUR graph coloring algorithm. SSLD uses semidefinite programming to identify an initial color class, aiming to improve coloring efficiency and has shown promising results in evaluations.

Key facts

• SSLD is a novel preprocessing technique for the DSATUR graph coloring algorithm.
• The method identifies an initial color class using semidefinite programming.
• SSLD was evaluated on over 1600 benchmark instances.
• The preprocessing step increases runtime by approximately 195 times compared to DSATUR alone.
