For the non-integral CVRP instances and VRPTW instances, I am unable to compute the same cost as given by the solution.

As discussed in #807, the common code in `CVRP::solve` and `VRPTW::solve` functions can be extracted to a separate template function.

**Suggestion:** In that case, introduce a threshold parameter on this fraction, that chooses between greedy+ or rollout. Instead of just doing it for epoch=0. (because it can occur in other epochs as …

[Nagata et al. (2010)](https://www.sciencedirect.com/science/article/pii/S0305054809001762
) presented the time warping concept together with the EAX crossover for VRPTW, improving on many best known…

Right now the `GeneticAlgorithm` class takes one or more crossover operators. In `GeneticAlgorithm::crossover()`, we do the actual crossover:

The original HGS implementation runs the local search on the initial solutions before inserting them into the population. We don't do this, and as a result, parents involved in the crossover are not l…

`state = TspState(customers, {})
initial_solution = greedy_repair(state, random_state)`
I change the cities into customers with VRPTW problems, and I see ur greedy_repair function only directly cons…

Running the benchmark script twice with a fixed number of iterations, I do not get the same average cost. So something's ever so slightly wrong. Might be in the benchmark script, might be in the stati…

We have a use case where lets say certain job are entitled with complete time of lets say 6-8 hours, during which that sales man will not be assigned the next job whose start time should be right wit…
