Enclosures for the solution set of parametric interval linear systems
International Journal of Applied Mathematics and Computer Science, 2012 We investigate parametric interval linear systems of equations. The main result is a generalization of the Bauer–Skeel and the Hansen–Bliek–Rohn bounds for this case, comparing and refinement of both.

Robustness of Interval Monge Matrices in Fuzzy Algebra
Mathematics, 2020 Max–min algebra (called also fuzzy algebra) is an extremal algebra with operations maximum and minimum. In this paper, we study the robustness of Monge matrices with inexact data over max–min algebra.

Complexity issues for the symmetric interval eigenvalue problem
Open Mathematics, 2014 We study the problem of computing the maximal and minimal possible eigenvalues of a symmetric matrix when the matrix entries vary within compact intervals. In particular, we focus on computational complexity of determining these extremal eigenvalues with

A Note on Inclusion Intervals of Matrix Singular Values [PDF]
Journal of Applied Mathematics, 2012 We establish an inclusion relation between two known inclusion intervals of matrix singular values in some special case. In addition, based on the use of positive scale vectors, a known inclusion interval of matrix singular values is also improved.

Matrix completion under interval uncertainty
European Journal of Operational Research, 2017 Matrix completion under interval uncertainty can be cast as matrix completion with element-wise box constraints. We present an efficient alternating-direction parallel coordinate-descent method for the problem. We show that the method outperforms any other known method on a benchmark in image in-painting in terms of signal-to-noise ratio, and that it ...

Propagating temporal relations of intervals by matrix
Applied Artificial Intelligence, 2002 Traditional temporal relations propagating is based on Allen's Interval Algebra. This paper proposes an alternative method to propagate temporal relations among intervals, in which 5 2 5 matrices are used to represent temporal relations of intervals. Hence, the propagation of temporal relations is transformed into a numerical computation.

Matrix Games with Interval-Valued 2-Tuple Linguistic Information
Games, 2018 In this paper, a two-player constant-sum interval-valued 2-tuple linguistic matrix game is construed. The value of a linguistic matrix game is proven as a non-decreasing function of the linguistic values in the payoffs, and, hence, a pair of auxiliary ...
