Problem: Calculus method of Game Theory {{2,-1},{-1,1}} [ Calculator, Method and examples ]

Solution:
Your problem `->` Calculus method of Game Theory {{2,-1},{-1,1}}

1. Saddle point testing
Players

		Player `B`
		`B_1`	`B_2`
Player `A`	`A_1`	2	-1
Player `A`	`A_2`	-1	1

We apply the maximin (minimax) principle to analyze the game.

		Player `B`
		`B_1`	`B_2`	Row Minimum
Player `A`	`A_1`	2	[-1]	`[-1]`
Player `A`	`A_2`	-1	(1)	`-1`
	Column Maximum	`2`	`(1)`

Select minimum from the maximum of columns
Column MiniMax = (1)

Select maximum from the minimum of rows
Row MaxiMin = [-1]

Here, Column MiniMax `!=` Row MaxiMin

`:.` This game has no saddle point.
