Abstract
Although engineering models are concerned with multi-step decision making in discrete time, the continuous analog may provide a good insight as well as a good approximation. Here we deal with the situation where a number of controlled processes are available, and one is allowed to switch from one process to another; the goal is to maximize a certain payoff which depends on those processes chosen by the switching mechanism. This type of problem occurs in dynamic allocation of resources (cf. armed bandit problems [1]), in supply and demand strategies [2], etc. We shall deal here with the case where the control mechanism can switch from one diffusion process to another in any non-anticipative way and with no penalty. This problem was studied by N.V. Krylov in a sequence of papers during the 1970’s; his results are described in detail in his book [3].
