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…
Companion Surface of Danger Cylinder and its Role in Solution Variation of P3P Problem
Bo wang, Hao Hu, Caixia Zhang
Traditionally the danger cylinder is intimately related to the solution stability in P3P problem. In this work, we show that the danger cylinder is also closely related to the mult…
New insights on Multi-Solution Distribution of the P3P Problem
Bo Wang, Hao Hu, Caixia Zhang
Traditionally, the P3P problem is solved by firstly transforming its 3 quadratic equations into a quartic one, then by locating the roots of the resulting quartic equation and veri…
Geometric Interpretation of side-sharing and point-sharing solutions in the P3P Problem
Bo wang, Hao Hu, Caixia Zhang
It is well known that the P3P problem could have 1, 2, 3 and at most 4 positive solutions under different configurations among its 3 control points and the position of the optical…
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…
