WebbAPPL is a C++ implementation of the SARSOP algorithm [1], using the factored MOMDP representation [2]. It takes as input a POMDP model in the POMDP or POMDPX file format and produces a policy file. It also contains a simple simulator for evaluating the quality of the computed policy. Webb23 maj 2008 · The POMDP solution exhibits interesting tracking behaviors, such as anticipatory moves that exploit target dynamics, informationgathering moves that reduce target position uncertainty, and energy-conserving actions that allow the target to get out of sight, but do not compromise long-term tracking performance.
