Module models

Expand description

A collection of models to represent problem and solution in Vehicle Routing Problem domain.

Modules§

ConstraintViolation: Specifies a result of hard route constraint check.
Extras: Specifies a type used to store any values regarding problem configuration.
Feature: An individual feature which is used to build a specific VRP variant, e.g., capacity restriction, job values, etc. Each feature consists of three optional parts (but at least one should be defined):
FeatureBuilder: Provides a way to build feature with some checks.
Goal: Specifies a goal of optimization as a list of Feature objectives with rules in lexicographical order.
GoalBuilder: Builds a Goal - a goal of optimization - composing multiple layers from objective functions in lexicographical order.
GoalContext: Defines Vehicle Routing Problem variant by global and local objectives: A global objective defines the way two VRP solutions are compared to select better one: for example, given the same number of assigned jobs, prefer fewer tours used instead of total solution cost.
GoalContextBuilder: Provides a customizable way to build goal context.
Lock: Contains information about jobs locked to specific actors.
LockDetail: Specifies lock details.
Problem: Defines a VRP problem. You can use a ProblemBuilder to create the one.
ProblemBuilder: Provides way to build a VRP definition.
Solution: Represents a VRP solution.
ViolationCode: Specifies a type for constraint violation code.

LockOrder: An enumeration which specifies how jobs should be ordered in tour.
LockPosition: An enumeration which specifies how other jobs can be inserted in tour.

FeatureConstraint: Defines feature constraint behavior.
FeatureObjective: Defines feature’s objective function behavior.
FeatureState: Provides the way to modify solution state when the search is performed.

FleetGroupKeyFn: Specifies a function to group actors based on their similarity.
