void eoVRPInit::operator() (eoVRP &  _gen  )  [inline]
+
+
+ +

+Functor member. +

+Initializes a genotype using an heuristic initializer.

Parameters:
+ + +
_gen Generally a genotype that has been default-constructed. Whatever it contains will be lost.

void eoVRPInit::HeuristicInitialization (eoVRP &  _gen  )  [inline, private]
+
+
+ +

+Heuristic initializer. +

+This initializer constructs and individual from routes. Each route is built in a constructive way. The first client of each route is selected trying to maximize a function depending on its time window and how far it is from the depot. We always try to select the hardest clients as seeds. Used seeds are stored so that different seeds are selected for different individuals and thus guarantee the diversity of the initial population.

Parameters:
+ + +
_gen The individual to be initialized.

bool  _seedCheckingOverride,

) [inline, private]
+
+
+ +

+Creates a new route. +

+Creates a new route selecting the best (hardest) client as seed and then adding the cheapest clients until one of the constraints (time window or vehicle's capacity) is broken.

Parameters:
+ + + + + +
_unvisited Vector of unvisited and thus available clients for constructing the new route.
_unvisitedIdx Position of the last univisted client in _unvisited vector.
_seedCheckingOverride If true, it overrides the seed checking mecanism. It must be always false for the first route and then true for the following ones. This way we will preserve diversity in our initial population as every individual will be initialized from a different initial route.
_route The brand new route we have constructed.

+
Returns:

bool eoVRPMutation::operator() (eoVRP &  _genotype  )  [inline, virtual]
+
+
+ +

+Functor operator. +

+Applies one of the four mutation operators available, each of them with a predefined (hard-coded) probability. These operators should be separated in different classes and their probabilities made parameterizable to do it in a more "paradisEO" way.

Returns:
True if the individual has been modified. False otherwise.

+Introduction

+The capacitated vehicle routing problem with time windows or CVRP-TW is a combinatorial optimization problem seeking to service a number of customers with a fleet of vehicles where the vehicles have a mimited capacity and the delivery locations have time windows within which the deliveries (or visits) must be made. Often the context is that of delivering goods located at a central depot to customers who have placed orders for such goods. Implicit is the goal of minimizing the cost of distributing the goods. Finding the global minimum for the cost function, except for the smallest instances, is computationally complex.

time windows or CVRP-TW is a combinatorial optimization problem seeking to service a number of customers with a fleet of vehicles where the vehicles have a mimited capacity and the delivery locations have time windows within which the deliveries (or visits) must be made. Often the context is that of delivering goods located at a central depot to customers who have placed orders for such goods. Implicit is the goal of minimizing the cost of distributing the goods. Finding the global minimum for the cost function, except for the smallest instances, is computationally complex.\section{AUTHORS}\label{main_authors} +\begin{TabularC}{3} +\hline +Dolphin project-team INRIA Futurs, 2007. &Antonio La\-Torre atorre[at]fi.upm.es &Thomas Legrand paradiseo-help[at]lists.gforge.inria.fr \\\hline +\end{TabularC} +\section{LICENSE}\label{main_LICENSE} +This software is governed by the Ce\-CILL license under French law and abiding by the rules of distribution of free software.

Often the context is that of +delivering goods located at a central depot to customers who have placed orders for such +goods. Implicit is the goal of minimizing the cost of distributing the goods. Finding the +global minimum for the cost function, except for the smallest instances, is +computationally complex. + +@section authors AUTHORS + + + + + + + +
