A numerical comparison of solvers for large-scale, continuous-time algebraic Riccati equations and LQR problems

open access: yes, 2020
In this paper, we discuss numerical methods for solving large-scale continuous-time algebraic Riccati equations. These methods have been the focus of intensive research in recent years, and significant progress has been made in both the theoretical ...

Reformulated Zagreb indices of thorny graphs and algorithms

open access: yesMathematics in Applied Sciences and Engineering
Molecular descriptors (graph indices) numerically describe the topologies of the chemicals. Graph indices are used to estimate certain properties of molecules. In this paper, reformulated first/second Zagreb indices for the thorny graph of any graph are
