One approach to guaranteeing safety in Reinforcement Learning is through cost constraints that are dependent on the policy. Recent works constrained RL have developed methods ensure enforced even at learning time while maximizing overall value of Unfortunately, as demonstrated our experimental results, such approaches do not perform well complex multi-level tasks, with longer episode lengths or...

Abstract David Chalmers advocates the view that phenomenon of consciousness is fundamentally different from all other phenomena studied in life sciences, positing a uniquely hard problem precludes possibility mechanistic explanation. In this paper, I evaluate three demarcation criteria for dividing into and easy problems: functional definability, puzzle accompanying phenomenon, first-person dat...

A graph class is hereditary if it closed under vertex deletion. We give examples of NP-hard, PSPACE-complete and NEXPTIME-complete problems that become constant-time solvable for every not equal to the all graphs.
