A result from the 1950's, Blackwell's Approachability Theorem, showed what was essentially a generalization of Von Neumann's minimax theorem for multi-dimensional payoffs. More recently, there has been a lot of work on constructing what are known as "no-regret algorithms", which provide a strong guarantee when optimizing an arbitrary sequence of convex functions. I'll show that two results, "existence of no-regret algorithms" and "Blackwell approachability", are essentially the same, each proving a convex-dual version of the other.
