Class AbstractOptimizationProblem<PAIR>

java.lang.Object

org.apache.commons.math3.optim.AbstractOptimizationProblem<PAIR>

Type Parameters:

PAIR - Type of the point/value pair returned by the optimization algorithm.

All Implemented Interfaces:

OptimizationProblem<PAIR>

public abstract class AbstractOptimizationProblem<PAIR>
extends java.lang.Object
implements OptimizationProblem<PAIR>

Base class for implementing optimization problems. It contains the boiler-plate code for counting the number of evaluations of the objective function and the number of iterations of the algorithm, and storing the convergence checker.

Since:

3.3
