Summary
Main objects here are stochastic programs, possibly non-convex. We develop an algorithm that combines gradient projection with the heavy-ball method. What emerges is a constrained, stochastic, second-order process. Some friction feeds into and stabilizes myopic approximations. Convergence obtains under weak and natural conditions, an important one being that accumulated marginal payoff remains bounded above.
