Numerical Optimal Control of HIV Transmission in Octave/MATLAB
Carlos Campos, Cristiana J. Silva, Delfim F. M. Torres
We provide easy and readable GNU Octave/MATLAB code for the simulation of mathematical models described by ordinary differential equations and for the solution of optimal control p…
Influence of the topology on the dynamics of a complex network of HIV/AIDS epidemic models
Guillaume Cantin, Cristiana J. Silva
In this paper, we propose an original complex network model for an epidemic problem in an heterogeneous geographical area. The complex network is constructed by coupling nonidentic…
Stability of a fractional HIV/AIDS model
Cristiana J. Silva, Delfim F. M. Torres
We propose a fractional order model for HIV/AIDS transmission. Local and uniform stability of the fractional order model is studied. The theoretical results are illustrated through…
A sufficient optimality condition for delayed state-linear optimal control problems
Ana P. Lemos-Paiao, Cristiana J. Silva, Delfim F. M. Torres
We give answer to an open question by proving a sufficient optimality condition for state-linear optimal control problems with time delays in state and control variables. In the pr…
