Richard Courant,Herbert Robbinsdominating set problem, and for ℓ ≥ . − 1 this is the PDS problem. Our hardness threshold for PDS also holds for ℓ-round PDS for all ℓ ≥ 4. We give a PTAS for the ℓ-round PDS problem on planar graphs, for .. We study variants of the greedy algorithm, which is known to work well on covering problems,

), the algorithm returns . element-disjoint Steiner trees. 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

Electoral Turnout: Mobilization in All Its Diversityts lower than in the 2007 second round (82% and 84% respectively) and much lower than the record level reached in the second round of the 1974 presidential election (87.3%). 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.
