Let G be a undirected connected graph. Given a set of g groups each being a subset of V (G), tree routing and coloring is to produce g trees in G and assign a color to each of them...

Power minimization under variability is formulated as a rigorous statistical robust optimization program with a guarantee of power and timing yields. Both power and timing metrics...
A global cardinality constraint (gcc) is specified in terms of a set of variables X = {x1, ..., xp} which take their values in a subset of V = {v1, ..., vd}. It constrains the numb...
