Sequential vertex colouring algorithms are compared on 3000 random graphs having \(n=25\) (25) 300 vertices and edge density \(p=0.1\), 0.25, 0.50, 0.75, 0.90. Fixed-order and dynamic-order approaches using the random/largest-first/smallest-last heuristic for choosing vertices and the minimum-index/lookahead rule for choosing colours are discussed. Detailed measurements are listed. The dynamic largest-first lookahead algorithm seems to be superior in most cases.
