Abstract: Reconfiguration problems arise when we wish to find a step-by-step transformationbetween two feasible solutions of a problem such that all intermediate results arealso feasible. We demonstrate that a host of reconfiguration problems derived fromNP-complete problems are PSPACE-complete, while some are also NP-hard to approximate. In contrast, several reconfiguration versions of problems in P are solvable in polynomial time.
