Optimal control problem for 3D micropolar fluid equations

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2020
In this paper we study an optimal control problem related to strong solutions of 3D micropolar fluid equations. We deduce the existence of a global optimal solution with distributed control and, using a Lagrange multipliers theorem, we derive first-order

Optimal Reinsurance Problem under Fixed Cost and Exponential Preferences

open access: yesMathematics, 2021
We investigate an optimal reinsurance problem for an insurance company taking into account subscription costs: that is, a constant fixed cost is paid when the reinsurance contract is signed.

Fractal variational principle for an optimal control problem

open access: yesJournal of Low Frequency Noise, Vibration and Active Control, 2022
The optimal control of a system governed by an elliptic equation has been widely applied in engineering, and it requires twice differentiability. Furthermore, the optimal control cannot effectively deal with unsmooth boundaries.

Cognitive Control as a Multivariate Optimization Problem [PDF]

open access: yesJournal of Cognitive Neuroscience, 2022
AbstractA hallmark of adaptation in humans and other animals is our ability to control how we think and behave across different settings. Research has characterized the various forms cognitive control can take—including enhancement of goal-relevant information, suppression of goal-irrelevant information, and overall inhibition of potential responses ...
