org.optaplanner.core.api.domain.solution.Solution
A Solution represents a problem and a possible solution of that problem. A possible solution does not need to be optimal or even feasible. A Solution's variables do not even have to be initialized.
A Solution is mutable. For scalability reasons, the same Solution instance, called the working solution, is continuously modified. It's cloned to recall the best solution.
This annotation described declarative properties of the planning solution. The planning solution class must implement this interface which is needed to get/set state. But the planning solution class must also be annotated with {@link PlanningSolution}describes declarative properties.
