At present,many scholars have made the new expansion to the probabilistic planning. This paper emphatically introduced the development of probabilistic planning in recent years, as well as the probabilistic planncr(FF-Rcplan).Then the International Probabilistic Planning Competition was presented. It enables the general scholars to have a more comprehensive understanding to the probabilistic planning.
