A Phase-1-Algorithm for Interior-Point-Methods: Worst-Case and Average-Case Behaviourtation-symmetry model. This stochastic model was the basis of the average case analysis of the simplex method in [1]. A phase-1-algorithm shall provide a starting point for an interior point method (IPM), if the LP is feasible and bounded, or otherwise indicate the infeasibility resp. unboundedness

Towards a Unified Framework for Randomized Pivoting Algorithms in Linear Programming linear program. The best bounds that depend only on the sizes of a basis and a nonbasis have been found for a family of randomized pivoting algorithms. However, the original descriptions and analyses of these algorithms use several different geometric and abstract settings. In this paper we present

The Constrained Crossing Minimization Problem A First Approachrwise distinct edges . ? . × ., find a drawing of .′ = (., . ? .) in the plane such that the combinatorial embedding II(.} of . is preserved and the number of edge crossings is minimum. This problem arises in the context of automatic graph drawing..We show that the constrained crossing minimization

Partitioning Cliques of Claw-Free Strongly Chordal Graphst the adjacency graph of these cliques is a tree. In particular, the presented results imply the existence of an ordering of the vertices, and a corresponding edge orientation, such that each directed path is contained in at most two maximal cliques. As shown by the authors in previous works, this a

Extreme Rays of the Cones of Subadditive Functionsre studied. A large class of extreme rays of the cone of monotone subadditive functions and all extreme rays of the cone of concave functions on . are found. Established set-theoretic relations between the cones allow to lessen the area where the search of extreme rays of the first two cones is wort

On the Forced Eckhaus Equation solutions and of their stability. In this note we review some recent results., concerning the Eckhaus equation in an external potential V(x) and the properties of its bound state solutions. Some new results, related to the time asymptotic behavior of the solutions, will also be reported.
