State Constrained Stochastic Optimal Control for Continuous and Hybrid Dynamical Systems Using DFBSDE

no code implementations11 May 2023 Bolun Dai, Prashanth Krishnamurthy, Andrew Papanicolaou, Farshad Khorrami

We develop a computationally efficient learning-based forward-backward stochastic differential equations (FBSDE) controller for both continuous and hybrid dynamical (HD) systems subject to stochastic noise and state constraints.

State Constrained Stochastic Optimal Control Using LSTMs

no code implementations5 Apr 2021 Bolun Dai, Prashanth Krishnamurthy, Andrew Papanicolaou, Farshad Khorrami

In this paper, we propose a new methodology for state constrained stochastic optimal control (SOC) problems.

Extreme-Strike Comparisons and Structural Bounds for SPX and VIX Options

Singular Perturbation Expansion for Utility Maximization with Order-$ε$ Quadratic Transaction Costs

no code implementations14 Oct 2019 Andrew Papanicolaou, Shiva Chandra

We present an expansion for portfolio optimization in the presence of small, instantaneous, quadratic transaction costs.

Portfolio Optimization

Consistent Time-Homogeneous Modeling of SPX and VIX Derivatives

no code implementations14 Dec 2018 Andrew Papanicolaou

This paper's main result is a method for the recovery of a stochastic volatility function by solving an inverse problem where the input is the VIX function given by a market model.
