The M/G/1 queue is a classical model used to represent a large number of real-life computer and networking applications. In this note, we show that, for coefficients of variation o...
The contentious debates between RISC and CISC have died down, and a CISC ISA, the x86 continues to be popular. Nowadays, processors with CISC-ISAs translate the CISC instructions i...
Probabilistic inference techniques can be used to estimate variable bias, or the proportion of solutions to a given SAT problem that fix a variable positively or negatively. Metho...
Abstract. We present a new method to break symmetry in graph coloring problems. While most alternative techniques add symmetry breaking predicates in a pre-processing step, we deve...
In this paper we consider the class of boolean formulas in Conjunctive Normal Form (CNF) where for each variable all but at most d occurrences are either positive or negative. This...

Recent work has shown the value of using unsatisfiable cores to guide maximum satisfiability algorithms (Max-SAT) running on industrial instances [5,9,10,11]. We take this concep...
We investigate the role of cycles structures (i.e., subsets of clauses of the form ¯l1 ∨ l2, ¯l1 ∨ l3, ¯l2 ∨ ¯l3) in the quality of the lower bound (LB) of modern MaxSAT ...
