Minors in random and expanding hypergraphs
We introduce a new notion of minors for simplicial complexes (hypergraphs), so-called homological minors. Our motivation is to propose a general approach to attack certain extrema...

Coupling aware timing optimization and antenna avoidance in layer assignment
The sustained progress of VLSI technology has altered the landscape of routing which is a major physical design stage. For timing driven routings, traditional approaches which con...

Solving MAX-r-SAT Above a Tight Lower Bound
We present an exact algorithm that decides, for every fixed r ≥ 2 in time O(m) + 2O(k2 ) whether a given multiset of m clauses of size r admits a truth assignment that satisfi...

An approach for integrating basic retiming and software pipelining
Basic retiming is an algorithm originally developed for hardware optimization. Software pipelining is a technique proposed to increase instruction-level parallelism for parallel p...
