Extremum seeking control is considered for a system with an objective function, and let the original objective function denote the function whose extremum the controller is intende…

Extremum seeking control involves an unknown plant model and objective function, and its high-frequency gain may change sign repeatedly near the optimum. A monitoring-function sche…

In stochastic approximation, consider a quantum signal approximation (QSA) algorithm whose observation noise is purely additive, so that the noise does not depend on the current st…

Finite-horizon approximation conjecture. For any $\delta>0$, any compact set $K \subset \mathbb{R}^n$, and any $t_0,T \in \mathbb{R}_{\geq 0}$, there exists…
