Using this algorithm, we get an approximation algorithm for the edge-disjoint version of the problem on planar graphs that improves on the previous approximation guarantees. We also show that the natural LP relaxation of the planar problem h

The appropriate relation to a philosophy is obviously that of philosophizing-along-with. Philosophizing-along-with takes the form of a sharing in our common rela

During the two presidential elections won by François Mitterrand in 1981 and 1988, a very high percentage of French voters went to the polls—86.8% and 85%, respectively.
