Multistep stochastic mirror descent for risk-averse convex stochastic programs based on extended polyhedral risk measures
(EMAp - Escola de Matemática Aplicada, 2016)
We consider risk-averse convex stochastic programs expressed in terms of extended polyhedral risk measures. We derive computable con dence intervals on the optimal value of such stochastic programs using the Robust Stochastic ...
Testing a predictive control with stochastic model in a balls mill grinding circuit
(Institute of Electrical and Electronics Engineers Inc., 2014-12)
In this paper, the formulation of a stochastic model and its subsequent incorporation into a predictive control of a balls mill grinding circuit, is presented. The apparition of stochastic variables is a consequence of ...
Optimal reactive power dispatch using stochastic chance-constrained programming
(2012-11-27)
Deterministic Optimal Reactive Power Dispatch problem has been extensively studied, such that the demand power and the availability of shunt reactive power compensators are known and fixed. Give this background, a two-stage ...

Non-asymptotic confidence bounds for the optimal value of a stochastic program
(EMAp - Escola de Matemática Aplicada, 2016)
We discuss a general approach to building non-asymptotic confidence bounds for stochastic optimization problems. Our principal contribution is the observation that a Sample Average Approximation of a problem supplies upper ...
PRICING VIA ANTICIPATIVE STOCHASTIC CALCULUS
(APPLIED PROBABILITY TRUST, 1994)
The paper proposes a general model for pricing of derivative securities. The underlying dynamics follows stochastic equations involving anticipative stochastic integrals. These equations are solved explicitly and structural ...
