In this lesson we're gonna return to cops and robbers, and we're going to press a little bit farther with that game, and think about what we can actually learn, From the equilibrium analysis in, in that game that was the game that you recall only had a mixed strategy Nash equilibrium okay and a natural thing when we're trying to analyze a real world situation with games is to change some of the incentives change the payoffs and see how behavior responds okay so what I've got up here first of all is the version, version one of cops and robbers the version that we worked on throughout unit nine the version that had no peer strategy Nash equilibrium.
