At the moment no. Forbidding waiting time leads to a different problem ("time windows with waiting costs") that is described for example here.
Hi Kuifje, Thanks for replying. I have edited my question to showcase what I am trying to solve. Is my usage of the library correct? Are Solomon instances not a case of CVRPTW problems?
Yes absolutely, Solomon instances are a reference for the CVRPTW. But in the classical CVRPTW, waiting time is allowed :) I believe you are using the library correctly.
Waiting time is allowed upon arrival at a node. This means that if a vehicle arrives at a node before the time window’s lower bound, the configuration remains feasible, it is considered that the driver waits before servicing the customer.
Is there a way of changing this behaviour?
Specifically, I am trying to solve Solomon instances (e.g.: C101.100) and the solution obtained opts to make a truck wait a significant amount before continuing.
