Cluster first route second heuristics

WebFeb 14, 2024 · For this purpose, we choose a route-first cluster-second (RFCS) heuristic. The RFCS heuristics has different components. First, we create a single tour using the nearest neighbor heuristic (NHH) . Afterwards, having created a single tour that contains all vertices, the tour is split equally in m segments, where m is the number of available trucks.
