On Erdős-Gallai and Havel-Hakimi algorithms

Havel in 1955 [28], Erdős and Gallai in 1960 [21], Hakimi in 1962 [26], Ruskey, Cohen, Eades and Scott in 1994 [69], Barnes and Savage in 1997 [6], Kohnert in 2004 [49], Tripathi, Venugopalan and West in 2010 [83] proposed a method to decide, whether a sequence of nonnegative integers can be the degree sequence of a simple graph. The running time of their algorithms is Ω(n) in worst case. In th...

Independence and the Havel-Hakimi residue

Favaron et al. (1991) have obtained a proof of a conjecture of Fajtlowicz’ computer program Graffiti that for every graph G the number of zeroes left after fully reducing the degree sequence as in the Havel-Hakimi Theorem is at most the independence number of G. In this paper we present a simplified version of the proof of Graffiti’s conjecture, and we find how the residue relates to a natural ...
