Class IntermediateSolver

java.lang.Object

org.ojalgo.optimisation.IntermediateSolver

All Implemented Interfaces:

Optimisation, Optimisation.Solver

Direct Known Subclasses:

ExpressionsBasedModel.DefaultIntermediate, NodeSolver

public abstract class IntermediateSolver
extends Object
implements Optimisation.Solver

A Optimisation.Solver implementation that wraps an ExpressionsBasedModel. Intended to be used when implementing solvers that iteratively modify a model instance and delegate to other solvers. The IntegerSolver makes use of this.
