Constructor Detail

OKA1

public OKA1()
Constructs the OKA1 problem.

Method Detail

evaluate

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.

Parameters:
solution - the solution to be evaluated

newSolution

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.

Returns:
a new solution for this problem
