Enum Constant Details

BOBYQA

public static final NetworkOptimizer.Algorithm BOBYQA

BOBYQA (Bound Optimization BY Quadratic Approximation). Derivative-free, trust-region method by M.J.D. Powell. Best for smooth objectives with box constraints and 2–20 variables. Builds a local quadratic model and iteratively improves it.

CMAES

public static final NetworkOptimizer.Algorithm CMAES

CMA-ES (Covariance Matrix Adaptation Evolution Strategy). Population-based global optimizer by N. Hansen. Robust for non-convex, noisy, or multi-modal objectives. Uses 5–50 variables effectively but requires more function evaluations than BOBYQA.

Method Details

values

public static NetworkOptimizer.Algorithm[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

an array containing the constants of this enum class, in the order they are declared

valueOf

public static NetworkOptimizer.Algorithm valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum class has no constant with the specified name

NullPointerException - if the argument is null
