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?
