Controlling Stochastic Resonance

Physical Review Letters, 1999
Stochastic resonance (SR) is a nonlinear noise-mediated cooperative phenomenon wherein the coherent response to a deterministic signal can be enhanced in the presence of an optimal amount of noise. Since its inception in 1981 [1], SR [2] has been demonstrated in diverse systems including sensory neurons, mammalian neuronal tissue, lasers, SQUIDs ...

Controlled Stochastic Systems

Cybernetics and Systems Analysis
Controlled Markov and semi-Markov processes and systems are considered. A review of inventory control problems is provided. One- and multiproduct models with different types of cost function and optimality criteria are considered. The optimality conditions and structures of optimal strategies in the problems are investigated.

Singular Stochastic Control Problems

SIAM Journal on Control and Optimization, 2004
Summary: We study an optimal singular stochastic control problem. By using a time transformation, this problem is shown to be equivalent to an auxiliary control problem defined as a combination of an optimal stopping problem and a classical control problem. For this auxiliary control problem, the controller must choose a stopping time (optimal stopping)

Nonconvexities in Stochastic Control Models

International Economic Review, 1995
Summary: Nonconvexities in the criterion function of adaptive control problems were first found about ten years ago with numerical methods. Recently they have been confirmed by Mizrach with analytical methods. He found that a source of the nonconvexity was the probing component of the cost- to-go.

Stochastic Optimal Control

1987
In the long history of mathematics, stochastic optimal control is a rather recent development. Using Bellman’s Principle of Optimality along with measure-theoretic and functional-analytic methods, several mathematicians such as H. Kushner, W. Fleming, R. Rishel. W.M. Wonham and J.M.

Stochastic programming and stochastic control

Trabajos de Estadistica y de Investigacion Operativa, 1975
We consider the passive and active approach to stochastic linear programming and mention also some alternative approaches. Stochastic control theory is discussed in its discrete version. The theory is illustrated with the help of econometric models for Indian economic planning. 1. Stochastic programming. 2. Stochastic control theory.
