org.apache.commons.math3.optim.BaseMultivariateOptimizer<PAIR>
PAIR
- Type of the point/value pair returned by the optimization
algorithm.public abstract class BaseMultivariateOptimizer<PAIR>
Base class for implementing optimizers for multivariate functions. It contains the boiler-plate code for initial guess and bounds specifications. It is not a "user" class.
