A Semismooth Newton-Type Method for the Nearest Doubly Stochastic Matrix Problem
Hao Hu, Haesol Im, Xinxin Li +1
We study a semismooth Newton-type method for the nearest doubly stochastic matrix problem where both differentiability and nonsingularity of the Jacobian can fail. The optimality c…
A Restricted Dual Peaceman-Rachford Splitting Method for QAP
Naomi Graham, Hao Hu, Haesol Im +2
We revisit and strengthen splitting methods for solving doubly nonnegative, DNN, relaxations of the quadratic assignment problem, QAP. We use a modified restricted contractive spli…
The linearization problem of a binary quadratic problem and its applications
Hao Hu, Renata Sotirov
We provide several applications of the linearization problem of a binary quadratic problem. We propose a new lower bounding strategy, called the linearization-based scheme, that is…
On Solving the Quadratic Shortest Path Problem
Hao Hu, Renata Sotirov
The quadratic shortest path problem is the problem of finding a path in a directed graph such that the sum of interaction costs over all pairs of arcs on the path is minimized. We…
