VRPH

VRPH is an open-source library of heuristics for generating solutions to Vehicle Routing Problems (VRPs). The VRPH software includes the following:

  • Many well-known heuristics for generating and improving feasible solutions to VRP instances (Clarke-Wright, two-opt, three-opt, etc.).
  • Two metaheuristics that can usually generate good solutions to large instances containing hundreds of customer locations in a matter of seconds. On well-studied benchmark problems, the solutions are typically within a percent or two of the best-known solution.
  • An algorithm that combines a metaheuristic with a set partitioning problem for even better solutions. This implementation currently uses the COIN Open Solver Interface (OSI) and the GLPK solver.
  • A modular design that can be extended to handle additional constraints.

VRPH was developed by Chris Groer (cgroerATgmailDOTcom), currently at Oak Ridge National Lab

News

  • April 2009: VRPH-1.0.0 is released.

Supported Platforms

  • GNU/Linux (g++)
  • Microsoft Windows
    • CYGWIN (w/ g++ compiler)
    • Visual C++
  • Mac OSX (g++)

Download

The current stable version of VRPH is 1.0 and the current release is 1.0.0.

Source code can be obtained either by

  • Downloading a snapshot of the source code for VRPH 1.0.0 from the VRPH source code download page, or
  • Checking out the latest stable source using a Git client.

The recommended method is to use Git because it makes it easier to obtain updates.

Quick Start Guide for Unix-like Environments

In a Unix-like environment (such as Linux or CYGWIN), the following commands may be used to obtain and compile the current release of VRPH, and then run a quick test on a small benchmark problem instance:

git clone -b releases/1.0.0 https://github.com/coin-or/VRPH.git
cd VRPH
make
make test
