My name is Istvan Elek (PhD) from the Eotvos Lorand University (http://www.elte.hu), Faculty of Computer Science (http://www.inf.elte.hu), Budapest, Hungary. I am an associate professor at the university, and the founder of a research group, which name is TEAM (http://team.elte.hu). TEAM is an acronym from Hungarian words, like T (spatial information), E (university), A (research), M (factory). The English acronym is SURF. My first publication on digital evolution machines appeared in 2008 at International Conference of Artificial Intelligence and Pattern Recognition, Orlando, USA. Next year I published the DEMs' problem in the Lecture Notes in Computer Science. If you would like to contact me, send an email to elek@map.elte.hu. There is a server, where you are now, and you can login, if you are an evolution researcher, who registered before by email. Registered users have database access with read-only rights, where DEMs' life can be observed via a graphic SQL command interface (no SQL injection, please).
