This paper searches for optimal strategies for the minimization of the number of high-risk
latent and active tuberculosis (TB) infectious individuals using real data from Ethiopia …

Many ordinary approaches in optimization are mathematical-based. Due to the limitations of
such methods, optimal problems have been commonly defined in single-objective and …

In this paper, the continuous classical boundary optimal control problem (CCBOCP) for triple
linear partial differential equations of parabolic type (TLPDEPAR) with initial and boundary …

Evaluation of control signal function is one of the critical subjects in the optimal control
problems. The optimal control is usually obtained by optimizing a performance index that is …

In this work, the classical continuous mixed optimal control vector (CCMOPCV) problem of
couple nonlinear partial differential equations of parabolic (CNLPPDEs) type with state …

In this paper, we propose a discrete mathematical model that describes the evolution of the”
covid-19” virus in a human population and the efforts made to control it. Our objective is to …

We devise a simple yet highly effective technique for solving general optimal control
problems in Excel spreadsheets. The technique exploits Excel's native nonlinear …

Cancer is a deadly disease causing a heavy health burden worldwide throughout the
recorded history. Chemotherapy is widely used to treat any type of cancer. With an …

Onchocerciasis also known as River Blindness, is a vector-borne disease caused by
Onchocerca volvulus and transmitted by infected female blackflies. It affects millions of …

Decisions and control of stochastic dynamical systems are challenging tasks. This thesis
explores the use of the stochastic approximation (SA) approach to solve discrete-time …
