,Cone-LP’s and semidefinite programs: Geometry and a simplex-type method,rograms. We study the notions of basic solutions, nondegeneracy, and feasible directions, and propose a generalization of the simplex method for a large class including LP‘s and SDP‘s. One key feature of our approach is considering feasible directions as a sum of . directions. In LP, these correspon

The quadratic assignment problem with a monotone anti-monge and a symmetric toeplitz matrix: Easy atric Toeplitz matrix. The following problems can be modeled via the AMT-QAP: (P1) The “Turbine Problem”, i. e. the assignment of given masses to the vertices of a regular polygon such that the distance of the gravity center of the resulting system to the polygon‘s center is minimized. (P2) The Trave

On optimizing multiplications of sparse matrices,ied to optimize memory allocation and to determine the optimal multiplication order for a chain product of sparse matrices. We adapt a recent algorithm by the author and show that the essence of the nonzero structure and hence, a near-optimal order of multiplications, can be determined in near-linea

Continuous relaxations for Constrained Maximum-Entropy Sampling,aximal determinant from a given . positive definite matrix, subject to linear constraints. We implement a branch-and-bound algorithm for the problem, using the new relaxation. The performance on test problems is far superior to a previous implementation using an eigenvalue-based relaxation.
