Iterated elimination of strictly dominated strategies (ISDS) is a solution concept that runs as follows. First, remove from the original game any strategy that is strictly dominated for player \(i\) (with respect to all of the opponents’ strategy profiles). After having removed the strictly dominated strategies in the original game, look at the resulting sub-game, remove the strategies which have become strictly dominated there, and repeat this process until the elimination does not remove any strategies. The profiles that survive this process are said to be iteratively non-dominated.
