A Q‐Learning Algorithm to Solve the Two‐Player Zero‐Sum Game Problem for Nonlinear Systems

International Journal of Adaptive Control and Signal Processing, Volume 39, Issue 3, Page 566-581, March 2025.
A Q‐learning algorithm to solve the two‐player zero‐sum game problem for nonlinear systems. ABSTRACT This paper deals with the two‐player zero‐sum game problem, which is a bounded L2$$ {L}_2 $$‐gain robust control problem. Finding an analytical solution to the complex Hamilton‐Jacobi‐Issacs (HJI) equation is a challenging task.

Mathematical Analysis and Optimal Control of Schistosomiasis Transmission Model

Biomath Communications, 2022
Schistosomiasis, a health challenge in many communities, is prevalent as the rate of infection is one in every thirty individuals. In this work, a deterministic model for schistosomiasis transmission dynamics is studied. The stability properties of equilibrium states, disease-free and endemic equilibria are established in terms of the basic ...

Enhancing Corrosion Resistance and Mechanical Strength of 3D‐Printed Iron Polylactic Acid for Marine Applications via Laser Surface Texturing

Advanced Engineering Materials, EarlyView.
Laser surface texturing significantly improves the corrosion resistance and mechanical strength of 3D‐printed iron polylactic acid (Ir‐PLA) for marine applications. Optimal laser parameters reduce corrosion by 80% and enhance tensile strength by 25% and ductility by 15%.

Mathematical optimization and robust control synthesis

, 2018
Nowadays, performance requirements imposed on system control designs have become more and more complicated. For many problems, it is very hard or even impossible to obtain analytic solutions. In recent years, powerful numerical computational tools for solving mathematical programming/optimization problems have been developed.

Experimental Evaluation of 100Cr6 Steel Microindented Surfaces Under Lubricated Nonconformal Point Contacts

Advanced Engineering Materials, EarlyView.
The tribological behavior of 100Cr6 steel spheres textured via Vickers microindentation is evaluated under lubricated sliding by varying both dimple size and density. Fine and dense textures significantly reduce friction across all lubrication regimes, while large dimples increase it.

Mathematical modeling and optimal control approaches for dengue

Iranian Journal of Numerical Analysis and Optimization
Summary: This research explores a continuous-time mathematical model that outlines the transmission dynamics of the dengue virus across different regions, involving both human and mosquito hosts. We propose an optimal strategy that includes awareness campaigns, safety measures, and health interventions in dengue-endemic areas, with the goal of reducing
