Base class for implementing optimizers for multivariate scalar functions,
subject to simple bounds: The valid range of the parameters is an interval.
The interval can possibly be infinite (in one or both directions).
This base class handles the boiler-plate methods associated to thresholds
settings, iterations and evaluations counting.
Type parameters: - <FUNC> – Type of the objective function to be optimized.
Deprecated: As of 3.1 (to be removed in 4.0). Since: 3.0 Deprecated: As of 3.1 since the
base class
contains similar functionality.
