Greedy Approximation Algorithms for Finding Dense Components in a Graph of finding subgraphs maximizing these notions of density for undirected and directed graphs. This paper gives simple greedy approximation algorithms for these optimization problems. We also answer an open question about the complexity of the optimization problem for directed graphs.

On the Relative Complexity of Approximate Counting Problemsty. We describe and investigate not only these two classes but also a third class, of intermediate complexity, that is not known to be identical to (i) or (ii). The third class can be characterised as the hardest problems in a logically defined subclass of #P.

Erfolgsfaktoren im Stiftungsmanagementertheless, this is a useful way of thinking about some approximation algorithms. In the talk I will present a few examples. My title is a play on the title of a classic paper on nonuniform computation “Turing Machines that take advice” (Karp and Lipton 1982).

https://doi.org/10.1007/978-3-8349-8456-2alient ideas in these algorithms and their analyzes are simple-to-explain and reflect a surprising degree of commonality. This note is intended as companion to our lecture at CONF 2000, mainly to give pointers to the appropriate references.
