Consider a simultaneous 4-player game where each player cheeses an effort level be tween 0 and 1 (any number between 0 and 1 is allowed, e.g., .04 or .179, etc. This is a continuous game.) The payoff to each player is calculated by finding the small est effort chosen by any of the 4 players, then multiplying that number by 4, and then subtracting the player's own effort. For example, if player 1 chose an effort of 0.5, and the lowest effort picked by any of the players was .25, then player 1's pay- off would be (4) (.25) - .5 = .5. Find all the Nash equilibria to this game and ex plain why they are Nash equilibria
