Hello, the routes in the distribution are not the k-shortest but rather the set of routes that was found to be the shortest for the given weights in successive iterations. The number of alternatives is limited by the option --max-alternatives (and by the number of iterations). If a faster alternative was never found, the vehicles only have their original route. regards, Jakob
