Abstract :
Postdiction is the task of finding the possible pasts of a physical system, given its model and current state. We present an appropriately modified version of Kuipers´ QSIM algorithm to perform postdiction by reverse qualitative simulation. The necessary changes to the algorithm are explained and the closed world assumption is discussed in this new light. The new algorithm can be used for diagnostic purposes
