Definition 3.7 (Constant Sum Game)
A 2-player n-strategy normal form game is called
constant sum game, if there exists a constant c
such that for each strategy profile a ∈ A 1 × A 2 :
µ 1 (a) + µ 2 (a) = c.
We usually set wlog c = 0 (zero sum games).
What we are really after is strategies. A pure
strategy is one where one action is chosen and
played. But does this always make sense?
