Package jline.opt.objectives

Class Objective

java.lang.Object

jline.opt.objectives.Objective

Direct Known Subclasses:

MaximizePerformance, MinimizeCost, MinimizeSystemResponseTime

public abstract class Objective
extends Object

Abstract base for line-opt objectives. An objective defines the scalar to minimize, optionally with attached constraints folded in as penalties by evaluateWithPenalty(jline.opt.results.EvaluationResult, java.util.Map<java.lang.String, java.lang.Object>, double). Mirrors native-Python line_solver.opt.objectives.Objective.
