Policy search is very effective. This is not a new finding as this article seems to suggest in the abstract. Variants of ES have been used for years (http://dl.acm.org/citation.cfm?id=1645634 http://dl.acm.org/citation.cfm?id=1645634). The article seems to ignore almost all the work in robotics, e.g. from Jan Peters' research group (http://www.jan-peters.net/ http://www.jan-peters.net/ -> publications). The good thing is that we have one more paper that justifies this research direction and a little bit more public attention.
