Othello syndrome (OS) is a type of paranoid delusional jealousy, characterized by the false absolute certainty of the infidelity of a partner. Because OS has infrequently occurred in patients with Parkinson's disease (PD), the characteristics of OS in PD remain unclear. We reviewed the clinical characteristics of this syndrome in PD. We reviewed 67 patients who had PD with OS. OS was more commo...

Monte-Carlo Tree Search (MCTS) is a very successful approach for improving the performance of game-playing programs. This paper presents the Accelerated UCT algorithm, which overcomes a weakness of MCTS caused by deceptive structures which often appear in game tree search. It consists in using a new backup operator that assigns higher weights to recently visited actions, and lower weights to ac...

A system based on artiicial evolution of neural networks for developing new game playing strategies is presented. The system uses marker-based genes to encode nodes in a neural network. The game-playing networks were forced to evolve sophisticated strategies in Othello to compete rst with a random mover and then with an-search program. Without any direction, the networks discovered rst the stan...

This paper describes Zenith, a discovery system that performs constructive induction. The system is able to generate and extend new features for concept learning using agenda-based heuristic search. The search is guided by feature worth (a composite measure of discriminability and cost). Zenith is distinguished from existing constructive induction systems by its interaction with a performance s...

Introduction The consideration of tragic pleasure is old, harkening back to contemporary critique of Greek tragedy. It is reasonable, however, to believe that no one, from then to now, has been able to deliberate upon the subject of delight in the portrayal of suffering while excluding all reference to reader response. Even if only implicitly conveyed, the focus of tragic pleasure is studying w...
