| Type | Game theory LP formulation |
| Difficulty | Challenging +1.2 This is a D2 game theory question requiring formulation of an LP from a payoff matrix in a zero-sum game. While it involves multiple steps (identifying saddle points, setting up constraints, formulating the LP), the procedure is algorithmic and follows standard textbook methods. It's moderately harder than average due to the abstract nature of game theory and LP formulation, but doesn't require novel insight beyond applying learned techniques. |
