A hybrid algorithm for the robust graph coloring problem
WebDec 29, 2024 · We introduce a dynamic version of the graph coloring problem and prove its fixed-parameter tractability with respect to the edit-parameter. This is used to present a turbo-charged heuristic for the problem that works by combining the turbo-charging technique with other standard heuristic tools, including greedy coloring. WebJan 27, 2024 · The vertex coloring problem is a well-known NP-hard problem and has many applications in scheduling. A conventional approach to the problem solves the k-colorability problem iteratively, decreasing k one by one. Whether a heuristic algorithm finds a legal k-coloring quickly or not is largely affected by an initial solution. physiotherapy eastwood
