Fixed edge hgs cvrp
Web• Route cost: the sum of edge costs for the sequence of nodes. For an edge from node i to node j, the edge cost is the Euclidean distance between node i and j. • Solution: a feasible solution consists of a set of valid routes visiting each city exactly once. • Solution cost: the sum of route costs for all routes in the solution.
