On optimal decisions under complete ignorance: A new criterion stronger than both Pareto and Maxmin

摘要: Abstract This paper discusses properties of a new defensive decision criterion which is strictly stronger than both Pareto and Maxmin starting with two-person game-against-nature situation where the maker has no information (not even probabilistic nature) on opponent's behaviour. The can be logically motivated without reference to or Maxmin. An ordinalistic view taken preference relations induced by connected quasi-order-valued utility function, assumptions are made about structure set strategies. In cases strategies finite, there connection what will called Lexicographic Decision Criterion.
