Quentin Thuillier,Isabelle Behm-AnsmantIn this and the next chapter we consider flows in networks. We have a digraph . with edge capacities . : .(.) → ℝ. and two specified vertices s (the .) and . (the .). The quadruple (.) is sometimes called a ..

https://doi.org/10.1007/978-1-4757-6523-6In this chapter we introduce the important concept of approximation algorithms. So far we have dealt mostly with polynomially solvable problems. In the remaining chapters we shall indicate some strategies to cope with .-hard combinatorial optimization problems. Here approximation algorithms must be mentioned in the first place.

Markus Kuhlmann,Blaga Popova,Wolfgang NellenSuppose we have . objects, each of a given size, and some bins of equal capacity. We want to assign the objects to the bins, using as few bins as possible. Of course the total size of the objects assigned to one bin should not exceed its capacity.

Linear Programming,In this chapter we review the most important facts about Linear Programming. Although this chapter is self-contained, it cannot be considered to be a comprehensive treatment of the field. The reader unfamiliar with Linear Programming is referred to the textbooks mentioned at the end of this chapter.
