Intersecting and Dense Restrictions of Clutters in Polynomial Time, all members have a common element. Dense clutters additionally do not have a fractional packing of value 2. We are looking at certain substructures of clutters, namely minors and restrictions..For a set of clutters we introduce a general sufficient condition such that for every clutter we can decid

,LP-Based Approximations for?Disjoint Bilinear and?Two-Stage Adjustable Robust Optimization,ere . and . are the number of packing constraints in . and . respectively. In particular, we show that there exists a near-optimal solution . such that . and . are “near-integral”. We give an LP relaxation of this problem from which we obtain the near-optimal near-integral solution via randomized ro

A Constant-Factor Approximation for Generalized Malleable Scheduling Under ,-Concave Processing Spehe schedule. The required processing time for each job is determined by the joint processing speed of the allocated machines. We study the case that processing speeds are job-dependent .-concave functions and provide a constant-factor approximation for this setting, significantly expanding the realm
