Optimal control of a social epidemic model with media coverage
Journal of Biological Dynamics, 2017 A new social epidemic model to depict alcoholism with media coverage is proposed in this paper. Some fundamental properties of the model including existence and positivity as well as boundedness of equilibria are investigated. Stability of all equilibria

A Dynamic Model for Fishery Resource with Reserve Area and Taxation
Journal of Applied Mathematics, 2012 The present paper deals with a dynamic reaction model of a fishery. The dynamics of a fishery resource system in an aquatic environment consists of two zones: a free fishing zone and a reserve zone.

Principal eigenvalues for k-Hessian operators by maximum principle methods
, 2017 For fully nonlinear k-Hessian operators on bounded strictly (k-1)-convex domains of Euclidian space, a characterization of the principal eigenvalue associated to a k-convex and negative principal eigenfunction will be given as the supremum over values of

Geometry of Optimal Control for Control-Affine Systems
Symmetry, Integrability and Geometry: Methods and Applications, 2013 Motivated by the ubiquity of control-affine systems in optimal control theory, we investigate the geometry of point-affine control systems with metric structures in dimensions two and three.

Optimal control of Cocoa Black pod disease: A multi-pronged approach
Franklin OpenThis study presents a novel approach to controlling cocoa black pod disease, caused by Phytophthora megakarya. Unlike previous methods, we employ a mathematical modeling framework based on Pontryagin’s Maximum Principle to optimize control strategies ...

, 2014 The paper presents a methodology for an optimal input design for model discrimination. To allow analytical solutions, the method, using Pontryagin’s maximum principle, is developed for non-linear single-state systems that are affine in their joint input.

Optimizing Variational Quantum Algorithms Using Pontryagin’s Minimum Principle
, 2017 We use Pontryagin’s minimum principle to optimize variational quantum algorithms. We show that for a fixed computation time, the optimal evolution has a bang-bang (square pulse) form, both for closed and open quantum systems with Markovian decoherence ...
