The rapidity distribution of Λ and Λ̄ produced in nucleus-nucleus collisions at CERN energies is studied in the framework of an independent string model with quark-antiquark as well as diquark-antidiquark pairs in the nucleon sea. It is shown that, besides the Λ-Λ̄ pair production resulting from the fragmentation of sea diquarks, final state interactions of(More)
Graph coloring is one of the most studied combinatorial optimization problems that can be used to model several practical problems. This paper develops a reduction of job shop scheduling problem with unit-time operations to mixed graph coloring. In this study, a methodology based on Mixed Integer Linear Programming and tabu search (TS) algorithm are(More)
