A Generalized A* Algorithm for Finding Globally Optimal Paths in Weighted Colored Graphs
Jaein Lim, Panagiotis Tsiotras
Both geometric and semantic information of the search space is imperative for a good plan. We encode those properties in a weighted colored graph (geometric information in terms of…
Covariance Steering with Optimal Risk Allocation
Joshua Pilipovsky, Panagiotis Tsiotras
This paper extends the optimal covariance steering problem for linear stochastic systems subject to chance constraints to account for optimal risk allocation. Previous works have a…
Learning Nash Equilibria in Zero-Sum Stochastic Games via Entropy-Regularized Policy Approximation
Yue Guan, Qifan Zhang, Panagiotis Tsiotras
We explore the use of policy approximations to reduce the computational cost of learning Nash equilibria in zero-sum stochastic games. We propose a new Q-learning type algorithm th…
Apollonius Allocation Algorithm for Heterogeneous Pursuers to Capture Multiple Evaders
Venkata Ramana Makkapati, Panagiotis Tsiotras
In this paper, we address pursuit-evasion problems involving multiple pursuers and multiple evaders. The pursuer and the evader teams are assumed to be heterogeneous, in the sense…
Forward-Backward Rapidly-Exploring Random Trees for Stochastic Optimal Control
Kelsey P. Hawkins, Ali Pakniyat, Evangelos Theodorou +1
We propose a numerical method for the computation of the forward-backward stochastic differential equations (FBSDE) appearing in the Feynman-Kac representation of the value functio…
Information-Theoretic Abstractions for Planning in Agents with Computational Constraints
Daniel T. Larsson, Dipankar Maity, Panagiotis Tsiotras
In this paper, we develop a framework for path-planning on abstractions that are not provided to the agent a priori but instead emerge as a function of the available computational…
