Move to be operated on a feasible solution.
You must implement this (one or more types are allowed) for your problem.
You must provide an apply as well as an evaluate method.
NOTE: this interface changed from 0.4.x to 0.5.x. The change was needed to provide a more general interface.
Operates this move on sol.
This should actually change the solution.
Evaluate the cost after the move.
What if we make this move? Local searches can be speed up by a substantial amount if we are able to efficiently evaluate the cost of the neighboring solutions without actually changing the solution.
