solve

public Optimisation.Result solve(Optimisation.Result kickStarter)

Specified by:

solve in interface Optimisation.Solver

terminate

public void terminate()

Overrides:

terminate in class SystemProcess

toArgumentString

public String toArgumentString(List<Variable> theVars,

toArgumentString

public String toArgumentString(Variable aVar)

validate

public boolean validate()

Specified by:

validate in interface Optimisation.Model

Returns:

true If eveything is ok. false The model is structurally ok, but the "value" breaks constraints - the solution is infeasible.

dispose

public void dispose()

Description copied from interface: Optimisation.Model

Cleanup when a model instance is no longer needed. The default implementation does nothing,

Specified by:

dispose in interface Optimisation.Model

Specified by:

dispose in interface Optimisation.Solver
