This directory contains two small memetic algorithm programs for the Vehicle 
Routing Problem with Stochastic Demand (VRPSD) under the preventive restocking 
policy. They both use orOpt local search, but while the ea version uses an 
approximated delta-function for the expected cost of an a priory tour, the
eaFlimflam version uses the TSP delta-function within the local search to
spead it up considerably.

Both versions are meant to be used with the following command line options
-a 1 meaning that we use adaptive mutation rate
-mr 0.5 meaning that the highest mtation rate is 0.5
