Summary
                  The paper is about path planning for optimal sensing with a mobile robot, a typical case in which the robot needs to learn about its pose and the environment in time constrained, being then the problem notoriously hard because robots are exhibit to complex dynamics and face unknown uncertainties.
The authors propose a Partially Observed Markov Decision Process (POMDP) with a utility function that depends on the belief state to model the finite horizon planning problem.
