Computational Experience with Stable Set Relaxations
Gerald Gruber, Franz Rendl · SIAM Journal on Optimization · 2003
We investigate relaxations for the maximum stable set problem based on the Lovász number $\vartheta(G)$ as an initial upper bound. We strengthen this relaxation by adding two classes of cutting planes, odd circuit and triangle inequalities. We present computational results using this tighter model on many classes of graphs.
