/**
* These strategies are used by an optimization process implemented within the Solver's
* method findOptimalSolution(Objective objective, Var objectiveVar, OptimizationStrategy optStrategy)
*
BASIC strategy iterates through solution assuming that each next solution has optimization objectives
* better than in a previous solution.
*
DICHOTOMIZE strategy implements a dichotomized search of an optimal solution.
* During the search it modifies an interval [objectiveMin; objectiveMax].
* First it is trying to find a solution in the [objectiveMin; objectiveMid].
* If it fails, it is looking at [objectiveMid+1; objectiveMax]. During this
* process it switches the search target: one time in looks at in the upper
* half of the selected interval, another time - to the lower half.
*
NATIVE strategy implements a search strategy that is the best for a concrete implementation.
