Method Detail

solve

public void solve(IntegerConstrainedProblem problem,
                  double tol)

Specified by:

solve in interface IntegerConstrainedMinimizer

search

public Vector search(int maxIterations,
                     Vector... initials)

Description copied from interface: Minimizer

Search for a minimizer that minimizes the objective function from the given starting points.

Specified by:

search in interface Minimizer

Parameters:

maxIterations - the maximum number of iterations

initials - the initial guesses; they could include information such as boundaries

Returns:

an (approximate) minimizer

minimum

public double minimum()

Description copied from interface: Minimizer

Get the minimum found.

This is especially useful for an objective function that takes a long time to compute.

Specified by:

minimum in interface Minimizer

Returns:

the minimum found
