2 What is it? EO is an open-source C++ library for building genetic algorithms EO is an open-source C++ library for building genetic algorithms EO is functional on Unix, Linux, Windows, and Mac OS X EO is functional on Unix, Linux, Windows, and Mac OS X EO works with gcc, g++, Visual C++, Builder compilers / environments EO works with gcc, g++, Visual C++, Builder compilers / environments EO comes with tutorials and (incomplete) documentation EO comes with tutorials and (incomplete) documentation

3 What else? Create genetic algorithms! What else? Create genetic algorithms! EO supports command line and file input of parameters – no recompile necessary EO supports command line and file input of parameters – no recompile necessary EO allows you to use bit string or real- valued chromosomes, or create your own EO allows you to use bit string or real- valued chromosomes, or create your own EO provides support for parallel processing EO provides support for parallel processing What can you do with it?
