Simple constructor with default settings.

Method Detail

isRestrictedToNonNegative

protected boolean isRestrictedToNonNegative()
Returns:
true if the variables are restricted to non-negative values.

getFunction

protected LinearObjectiveFunction getFunction()
Returns:
the optimization type.

getConstraints

protected Collection<LinearConstraint> getConstraints()
Returns:
the optimization type.

optimize

public PointValuePair optimize(OptimizationData... optData)
                        throws TooManyIterationsException
Stores data and performs the optimization.

Overrides:
optimize in class MultivariateOptimizer
Parameters:
optData - Optimization data. The following data will be looked for:
Returns:
a point/value pair that satifies the convergence criteria.
Throws:
TooManyIterationsException - if the maximal number of iterations is exceeded.
