Thank you for your contributions to Wikipedia. Before saving your changes to an article, please provide an edit summary, which you forgot to do before saving your recent edit to State of the art. Doing so helps everyone understand the intention of your edit (and prevents legitimate edits from being mistaken for vandalism). It is also helpful to users reading the edit history of the page. Thank you. --Edcolins (talk) 10:58, 26 December 2010 (UTC)
