Question

Which of the following is a sufficient condition for a system to be stable?

(a) Gauss criterion

(b) Convergence criterion

(c) Stopping criterion

(d) Scarborough criterion

I have been asked this question during an interview.

My question comes from Discretization Aspects in section Basic Aspects of Discretization, Grid Generation with Appropriate Transformation of Computational Fluid Dynamics

Answer 1

Right answer is (d) Scarborough criterion

Easiest explanation: A system of linear equations can be taken as stable if it satisfies the Scarborough criterion. Scarborough criterion gives a condition about the coefficient matrix of the algebraic system. This criterion also gives information about the boundedness of the problem.
