New GRALS framework improves solutions for minimum vertex cover problem

Researchers have developed GRALS, a new local search framework designed to tackle the minimum vertex cover (MVC) problem, a fundamental NP-hard combinatorial optimization challenge. GRALS integrates vertex probability priors learned from a graph convolutional network with an expansion revelation elimination operator to enhance solution quality and efficiency. Experiments show GRALS outperforms existing methods, achieving the best-known solutions for a significant majority of tested instances, particularly on large-scale graphs. AI
