It is one of the toughest places to live on Earth. Now, a six-strong team of astronauts is preparing to head to the Dhofar desert in Oman next year in an attempt to simulate what life will be like on Mars. The astronauts are using the trial as a'dress rehearsal' for future missions to the red planet, and will carry out 19 experiments designed to search for traces of life. In February 2018, They will spend four weeks living in almost complete isolation. Among the scientific equipment they will take with them for the Amadee-18 experiment will be a a drone, robotic rovers and a hydroponic greenhouse.

Partially observable stochastic games (POSGs) are a robust and precise model for decentralized decision making under conditions of imperfect information, and extend popular Markov decision problem models. Complexity results for a wide range of such problems are known when agents work cooperatively to pursue common interests. When agents compete, things are less well understood. We show that under one understanding of rational competition, such problems are complete for the class NEXP^NP. This result holds for any such problem comprised of two competing teams of agents, where teams may be of any size whatsoever.
