The program racket.exe is a DOS-based
program which demonstrates the divergence
property of DE. A cloud of points is
located in the corner of a racket
shaped ROA (Region Of Acceptability) with
a flat objective function surface inside.
DE causes the cloud to spread over the
racket handle into the most voluminous 
part of the ROA. The yellow circle marks
the mean vector of the entire population.

Usage:
-----

Copy racket.exe, racket.dat, egavga.bgi
into a directory, open a DOS-box within
this directory and type

racket racket.dat

at the command prompt. Any key press stops 
the program.
