We extend the voluntarily separable repeated Prisoner’s Dilemma (Fujiwara-Greve and Okuno-Fujiwara, 2009) to continuous actions. We show that there is a (constrained) efficient bimorphic equilibrium which is robust under evolutionary pressure. It consists of a cooperative strategy and a myopic defection strategy so that our model provides a foundation to incomplete information models as well.

Order copies of this and other ACL proceedings from: The workshop focused on Multi-Word Expressions (MWEs), which represent an indispensable part of natural languages and appear steadily on a daily basis, both novel and already existing but paraphrased, which makes them important for many natural language applications. Unfortunately, while easily mastered by native speakers, MWEs are often non-...

Previous observational studies have found increasing primary production (PP) in response to declining sea ice cover in the Arctic Ocean. In this study, under-ice PP was assessed based on three coupled ice-ocean-ecosystem models participating in the Forum for Arctic Modeling and Observational Synthesis (FAMOS) project. All models showed good agreement with under-ice measurements of surface chlor...
