Graph coloring optimization problem
WebGraph coloring is computationally hard. It is NP-complete to decide if a given graph admits a k-coloring for a given k except for the cases k ∈ {0,1,2} . In particular, it is NP-hard to compute the chromatic number. … WebMar 30, 2024 · Ant algorithm [48, 49] was first proposed as a meta-heuristic approach to solving complex optimization problems such as traveling salesman problem (TSP) and quadratic assignment problem (QAP).Ant’s behaviors biologically inspire ACO algorithms to determine the pheromone-based shortest path between the nest and a food source.
