Fast informed bound

WebFIB (Fast Informed Bound) [3], do not plan in the space of beliefs, but plan over the state space. Consequently, these algorithms require much less memory and computation than belief-space planners, and have been widely used in robot control and manipulation [6], [7], [8], even if they are not able to represent optimal policies. WebBoth of these can work with arbitrary points of the belief space and can be enhanced by various heuristic point selection strategies. Also 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 boun...
