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.

Stability in nonlinear neutral differential equations with infinite delay [PDF]
Mathematica Moravica, 2014 In this paper we use the contraction mapping theorem to obtain asymptotic stability results of the nonlinear neutral differential equation with infinite delay d/dt x(t) = -a(t) x (t - T1(t)) + d/dt Q (t, x (t - T2(t))) + ∫ D(t,s) f (x (s))ds.

Delay difference equations in infinite-dimensional spaces
Journal of Difference Equations and Applications, 2006 We present explicit stability conditions for the solutions of nonlinear delay difference equations defined in infinite-dimensional spaces , where X is a Banach space; are linear bounded operators and the nonlinearities satisfy a local comparison condition.
