“…Along this line, [13] studied the maximum principle for delayed stochastic optimal control problems in which the control domain is assumed to be convex and both the control variable and its delay part enter the diffusion coefficient. After that, [14] studied the optimal control problem in which the control system is described by a fully coupled anticipated forward-backward stochastic differential delayed equation, and then [15] generalized [13] to the case when the system involves both continuous and impulse controls and the coefficients are random. In practice, sometimes state constraints are inevitably encountered in stochastic optimal control problems; see, for example, [6,10,16,17].…”
