Morality metrics on iterated prisoner’s dilemma players

Abstract

Research regarding Iterated Prisoner’s Dilemma (IPD) tournaments generally focuses on the objec-tive performance of strategies. This paper instead discusses moral judgement of strategies, and ana-lyzes IPD stratagies’ behaviors through clearly de-fined morality functions. No single moral code is accepted by everyone, so multiple moral views are represented in this paper. Its purpose is not to ar-gue for a specific moral view (or to attempt to cover all possible views), but rather to present a useful method of moral analysis as well as some interesting, mathematically well-defined morality functions cor-responding (or at least relevant) to real-world views represented in society.
