approaches and existing frameworks that implement such approaches, I am
inclined to use OpenTS because its ease of use and clean design. I would like
to share ideas with anyone who has implemented a VRPTW using OpenTS, and maybe
get a hint or two about what would be a good design for moves, table size,
objective function, etc.</span></font></p>
