The Q0-matrix completion problem [PDF]
Arab Journal of Mathematical Sciences, 2020 A matrix is a Q0-matrix if for every k∈{1,2,…,n}, the sum of all k×k principal minors is nonnegative. In this paper, we study some necessary and sufficient conditions for a digraph to have Q0-completion. Later on we discuss the relationship between Q and Q0-matrix completion problem. Finally, a classification of the digraphs of order up to four is done

Binary Matrix Completion With Nonconvex Regularizers
IEEE Access, 2019 Many practical problems involve the recovery of a binary matrix from partial information, so the binary matrix completion (BMC) technique has increasingly been of interest in machine learning. In particular, we consider a special case of the BMC problems,

Image Completion with Hybrid Interpolation in Tensor Representation
Applied Sciences, 2020 The issue of image completion has been developed considerably over the last two decades, and many computational strategies have been proposed to fill-in missing regions in an incomplete image. When the incomplete image contains many small-sized irregular

The P_0-matrix completion problem
The Electronic Journal of Linear Algebra, 2002 A partial matrix is a rectangular array in which some entries are specified while others are free to be chosen. A completion of a partial matrix is a specific choice of values for the unspecified entries. A pattern for \(n \times n\) matrices is a list of positions of the matrix. An \(n \times n\) matrix is called a \(P_0\)-matrix (respectively, a \(P\)

Matrix Tri-Factorization Over the Tropical Semiring
IEEE Access, 2023 Tropical semiring has proven successful in several research areas, including optimal control, bioinformatics, discrete event systems, and decision problems. Previous studies have applied a matrix two-factorization algorithm based on the tropical semiring

Robust low‐rank Hankel matrix recovery for skywave radar slow‐time samples
IET Radar, Sonar & Navigation, 2021 In skywave radar, the slow‐time samples received in a certain range‐azimuth cell are usually processed for signal analysis and target detection. Particularly, to extract the principal components, such as sea clutter and target signal, in slow‐time ...

A New Sparse Quasi-Newton Update Method
Sultan Qaboos University Journal for Science, 2012 Based on the idea of maximum determinant positive definite matrix completion, Yamashita proposed a sparse quasi-Newton update, called MCQN, for unconstrained optimization problems with sparse Hessian structures.

Hybrid time-quality-cost trade-off problems
Operations Research Perspectives, 2018 Agile and hybrid project management has become increasingly popular among practitioners, particularly in the IT sector. In contrast to the theoretically and algorithmically well-established and developed time-cost and time-quality-cost project management

A Dual-System Reinforcement Learning Method for Flexible Job Shop Dynamic Scheduling
Shanghai Jiaotong Daxue xuebao, 2022 In the production process of aerospace structural parts, there coexist batch production tasks and research and development (R&D) tasks. Personalized small-batch R&D and production tasks lead to frequent emergency insertion orders.
