Fast informed bound
WebAlso introduced is a new method for computing an initial upper bound – the fast informed bound method. This method is able to improve significantly on the standard and commonly used upper bound computed by the MDP-based method. The quality of resulting bounds are tested on a maze navigation problem with 20 states, 6 actions and 8 observations. Webproduct in the fast informed bound algorithm described in Sec. 2.3, it is sufficient to specify TZ. Given a POMDP P, the goal is to find a policy π that ... A simple and fast lower bound Q on thefunction can Q-be computed by finding the value function of blind strate-gies (Hauskrecht 1997) that ignore all observations by al- ...
