Windows executables

Here is a set of applications compiled with VRPH.  They are compiled for Windows and "should" work on a 32-bit Windows machine.  If you run into issues regarding MSVCRT.dll and things like that, you need to find that file and add it to your PATH (Google is your friend here).  Finally, you will have to rename the files from .bin to .exe since I can't upload .exe's to this site.  All the applications are command line utilities and help is available by using option -help or just using 0 arguments. Here is a summary of the applications:

• • vrp_ej:  An implementation of a neighborhood ejection/injection algorithm to "polish" good solution

  • vrp_initial: A simple demo to show how to use the Clark-Wright and sweep algorithms to generate initial solutions

  • vrp_plotter:  A utility to plot solutions to a VRP instance to a .ps file.  Can create .pdf files if you have the epstopdf.exe in your PATH

  • vrp_rtr:  An implementation of the RTR metaheuristic to generate good solutions to a VRP instance.  This has many command line options

  • vrp_sa:  An implementation of a Simulated Annealing metaheuristic.  Solution quality is ok, but not as good as RTR

One additional application that is not posted here is the vrp_sp application that uses GLPK to solve a set partitioning problem.  I have not yet compiled this for Windows
