tell me some forms about emd algorithm

Do you mean Google's EMD (Exact Match Domain) Update?

Have you already searched these forums for existing discussions on the topic?

In addition, Search Engine Land is always a good place to start looking for info about search engines: http://searchengineland.com/library/google/emd-update

Google did EMD update for those site who have keyword related name in his domain name and his work was not qualityful.

EMD update penalize number of sites who are using exact title in their domain name.

Thanks for discussing this popualr trick to get the support for seo; I would like to divert this discussion by asking about the effective methods to save the web sites with excat keyword domain name.
