Coverage Problem of Wireless Sensor Networks,ficient conditions respectively in the situations that the density function achieves its minimum value on a set with positive Lebesgue measure or at finitely many points. We propose also an economical scheme for the coverage of sensor networks with empirical distributions.

As a byproduct, we classify (i) completely those complete tripartite graphs . . and (ii) almost completely those complete bipartite graphs . . (for . ≤ 6) according to their choice numbers.

We also obtain a sufficient and necessary condition of Berge-type to verify if a heterochromatic matching . of . is maximum.

Supply Chain Management with SAP APO™we must introduce other operations than cross-operation for transforming them by using only simple graphs. Then we naturally reach to a question: is there a sufficient set of operations for this purpose? For this problem, this paper shows a negative result that there is no such finite set of operations.
