public abstract class LqnDecisionVariable
extends DecisionVariable

Abstract base for LayeredNetwork (LQN) decision variables. Flat decision variables mutate a Network; LQN variables mutate a LayeredNetwork, so the flat apply(Network, Object) is invalid here and throws, while applyLqn(LayeredNetwork, Object) carries the LQN mutation. The evaluator branches on problem.isLayered() and calls applyLqn for LQN variables. Mirrors the LQN variable classes in native-Python line_solver.opt.variables.

Method Details

apply

public final void apply(Network model,
 Object value)

Invalid for LQN variables: they apply to a LayeredNetwork, not a flat Network. The evaluator's layered path calls applyLqn(jline.lang.layered.LayeredNetwork, java.lang.Object) instead.

Specified by:

apply in class DecisionVariable

applyLqn

public abstract void applyLqn(LayeredNetwork model,
 Object value)

Apply a decoded value to a (copied) LayeredNetwork model.
