      • hasSolutionHint

        public boolean hasSolutionHint()
         Solution hint.

 If a feasible or almost-feasible solution to the problem is already known,
 it may be helpful to pass it to the solver so that it can be used. A solver
 that supports this feature will try to use this information to create its
 initial feasible solution.

 Note that it may not always be faster to give a hint like this to the
 solver. There is also no guarantee that the solver will use this hint or
 try to return a solution "close" to this assignment in case of multiple
 optimal solutions.
