A Lagrangian-DNN relaxation: a fast method for computing tight lower bounds for a class of quadratic optimization problems
We propose an efficient computational method for linearly constrained quadratic optimization problems (QOPs) with complementarity constraints based on their Lagrangian and doubly ...

Spectral simplex method
We develop an iterative optimization method for nding the maximal and minimal spectral radius of a matrix over a compact set of nonnegative matrices. We consider matrix sets with...
