Constructs the Poloni problem.

Method Detail


public void evaluate(Solution solution)
Description copied from interface: Problem
Evaluates the solution, updating the solution's objectives in place. Algorithms must explicitly call this method when appropriate to evaluate new solutions or reevaluate modified solutions.

solution - the solution to be evaluated


public Solution newSolution()
Description copied from interface: Problem
Returns a new solution for this problem. Implementations must initialize the variables so that the valid range of values is defined, but may leave the actual value at a default or undefined state.

a new solution for this problem
