Enum OptimizationStrategy

java.lang.Object

java.lang.Enum<OptimizationStrategy>

javax.constraints.OptimizationStrategy

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<OptimizationStrategy>

public enum OptimizationStrategy
extends java.lang.Enum<OptimizationStrategy>

These strategies are used by an optimization process implemented within the Solver's method findOptimalSolution(Objective objective, Var objectiveVar, OptimizationStrategy optStrategy)
BASIC strategy iterates through solution assuming that each next solution has optimization objectives better than in a previous solution.
DICHOTOMIZE strategy implements a dichotomized search of an optimal solution. During the search it modifies an interval [objectiveMin; objectiveMax]. First it is trying to find a solution in the [objectiveMin; objectiveMid]. If it fails, it is looking at [objectiveMid+1; objectiveMax]. During this process it switches the search target: one time in looks at in the upper half of the selected interval, another time - to the lower half.
NATIVE strategy implements a search strategy that is the best for a concrete implementation.

Method Detail

valueOf

public static OptimizationStrategy valueOf(java.lang.String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (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:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null

values

public static OptimizationStrategy[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (OptimizationStrategy c : OptimizationStrategy.values())
    System.out.println(c);

Returns:

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