What is EO? |
EO is a templates-based, ANSI-C++ compliant evolutionary computation library. It contains classes for almost any kind of evolutionary computation you might come up to - at least for the ones we could think of. It is component-based, so that if you don't find the class you need in it, it is very easy to subclass existing abstract or concrete classes. EO was started by the Geneura Team at the University of Granada, headed by Juan Julián Merelo. The original Web site is also the only place where you will find old releases of EO (up to 0.8.7), but beware that it is not compatible at all with the current version. The developement team has then been reinforced by Maarten Keijzer, the C++ wizzard, and Marc Schoenauer. Later came Jeroen Eggermont, who, among other things, did a lot of work on GP, Sébastien Cahon, who developped the parallel version of EO, ParadisEO, Olivier König, who did a lot of useful additions and cleaning of the code and Jochen Küpper, working on infrastructure maintenance. |
Platforms |
EO should work on Windows and any Un*x-like operating system with a standard-conforming C++ development system. Recent versions of EO have been tested on the following platforms:
If you have tested EO on a system not listed here, please let us know. If you are working on a system with an older C++ compiler there is a good chance that eo-0.9.3z.1 works. It is tested on Linux with gcc-2.9x and several systems (IRIX, Solaris) with egcs. |
Documentation |
The tutorial demonstrates that writing an evolutionary algorithm evolving your own structures is now easy, using ready-to-use template files. Although the tutorial has not been upgraded for some time now and refers to version 0.9.2 of EO, it nevertheless remains the best way to dive into EO. You can start by trying it on-line at LRI or SourceForge, before downloading it. The tutorial is also included in the released sources. The latest tutorial release includes a introduction to ParadisEO, the parallel version of EO. The complete code is also well documented and you can look at the generated interface documentation. The easiest way to create a complete new EO-project, even for new genomes, is to use the script provided in tutorial/Templates/; see the README in that directory and lesson 5 of the tutorial for detail. |
Presentations |
A functional and "philosophical" overview of EO was presented at EA'01 conference. You can download the paper or the slides. A PowerPoint presentation shows the EO philosophy, and it includes a Visual Basic macro for evolving objects in Visual Basic for Applications. You can also look a the list of publications that used EO to solve real problems. |
Download |
The current release is EO 1.0. It supports any Standard-compliant C++ compiler. You can obtain the latest version directly via cvs or download a daily snapshot from LRI. All releases can be obtained from the SourceForge download area. |
Mailing Lists |
We would like EO to be an open development effort; that is why we have created mailing lists to discuss future developments, solve technical problems, announce releases, publish patches, and discuss evolutionary computation in general. Browse the archives or join the EO mailing lists. |
