“…Indeed, optimal controls may not even exist in many situations, while near-optimal controls always exist. Various kinds of near-optimal control problems have been investigated in [6], [10], [12], [11], [13], [16], [18], [31], [32], [33]. In an interesting paper, Zhou [33] established second-order necessary as well as sufficient conditions for near-optimal stochastic controls for controlled diffusion, where the coefficients were assumed to be twice continuously differentiable.…”
