Method Detail

solve

public Optimisation.Result solve(Optimisation.Result kickStarter)

toString

public String toString()

Overrides:

toString in class Object

extractSolution

protected MatrixStore<Double> extractSolution()

Description copied from class: GenericSolver

Should be able to feed this to GenericSolver.evaluateFunction(Access1D).

Specified by:

extractSolution in class GenericSolver

initialise

protected boolean initialise(Optimisation.Result kickStarter)

Specified by:

initialise in class IntegerSolver

needsAnotherIteration

protected boolean needsAnotherIteration()

Specified by:

needsAnotherIteration in class IntegerSolver

validate

protected boolean validate()

Description copied from class: IntegerSolver

Should validate the solver data/input/structue. Even "expensive" validation can be performed as the method should only be called if Optimisation.Options#validate is set to true. In addition to returning true or false the implementation should set the state to either Optimisation.State#VALID or Optimisation.State#INVALID (or possibly Optimisation.State#FAILED). Typically the method should be called at the very beginning of the solve-method.

Specified by:

validate in class IntegerSolver

Returns:

Is the solver instance valid?
