    Verify These Games are Convex-Concave

    I have to verify these games are convex-concave: a) f(p,q)=-(pq)^2 f(p,q)=-(pq)^2 b) f(p,q)=-(p^2-2p+1)(q^2+4q+5) f(p,q)= -(p^2-2p+1)(q^2+4q+5) I am a bit confused as i thought i was supposed to take the second derivative with respect to p, show it is positive then take the second...

    This question illustrates the following theorem. If one player of a 2-person zero-sum game employs a fixed strategy, then the opponent has an optimal counter strategy that is pure. In other words, if Player I knows that Player II is using a particular mixed strategy y, then Player I can maximize...
