TL;DR: A variant of the spectral projected gradient algorithm with a specially designed line search is introduced to solve the EiCP and computational experience shows that the application of this algorithm to the logarithmic function formulation is a quite efficient way to find a solution to the symmetric Ei CP.

TL;DR: The eigenvalue complementarity problem (EiCP) where at least one of its defining matrices is asymmetric is discussed, and the EiCP is shown to be equivalent to finding a global minimum of an appropriate merit function on a convex set Ω defined by linear constraints.

TL;DR: A non-local fractional (non-integer) order model is proposed, which is carried out to evaluate the cost and the effectiveness of proposed control measures during the intervention period, showing the superiority of obtained results with respect to previous ones.

TL;DR: The research presented in this paper addresses the problem of fitting real data collected by the Florida HRSV surveillance system by using a periodic SEIRS mathematical model.

TL;DR: In this paper, the problem of fitting real data collected by the Florida HRSV surveillance system by using a periodic SEIRS mathematical model was addressed, and a sensitivity and cost-effectiveness analysis of the model was done and an optimal control problem was formulated and solved with treatment as the control variable.
