Write down the adjacency matrix of the network shown.
When a connection in a network does not have an arrow, it is said to be ‘undirected’. An undirected connection between nodes and is equivalent to a directed connection from to together with a directed connection from to . Determine the adjacency matrix of the network shown.
Players and play a game in which they both call “heads” or “tails” at the same time. They use the payoff matrix , where the first row and column represent “heads” and the second row and column represent “tails.” Describe the payoff rules for this game.
