To get a first impression of DeWin it is recommended to
copy the entire DeWin directory on your computer and
start the executables in the various subdirectories.

The default problem in the DeWin-directory is
the Chebyshev problem. If any of the other problems
shall be treated, go to the appropriate subdirectory
and copy the files eval.cpp, graphics.h, and in.dat
to the DeWin-directory.

There are two ways to work with DeWin:

1) As a Windows application under Microsoft Windows ®.
   For example, in Visual C++ you have to generate a 
   workspace of type "Win32Application". The compiler 
   switch "DO_PLOTTING" should be defined. Then insert
   all .cpp files into the project and go to Build | Rebuild All
   to obtain an executable code. Note that the plotting
   features are working only for the Win32 environment.

2) As a Windows console application under Microsoft Windows ®.
   Generate a workspace of type "Win32ConsoleApplication".
   Make sure the compiler switch "DO_PLOTTING" is undefined.
   Then insert all .cpp files into the project and go to 
   Build | Rebuild All to obtain an executable code.
   With this source code configuration the code should be
   portable to other operation systems with only minor
   modifications.

It has been tried to keep the code as simple and efficient
as possible while still making provisions for many features
like constraint handling, various DE-variants, plotting, etc..
The plotting features are fairly rudimentary and shall assist
in observing the optimization progress.
