Vh. Vu, On some simple degree conditions that guarantee the upper bound on the chromatic (Choice) number of random graphs, J GRAPH TH, 31(3), 1999, pp. 201-226
is well known that almost every graph in the random space G(n, p) has chrom
atic number of order O (n;Dl log(np)), but it is not clear how we can recog
nize such graphs without eventually computing the chromatic numbers, which
is NP-hard. The first goal of this article is to show that the above-mentio
ned upper bound on the chromatic number can be guaranteed by simple degree
conditions, which are satisfied by G(n,p) almost surely for most values of
p. It turns out that the same conditions imply a similar bound for the choi
ce number of a graph. The proof implies a polynomial coloring algorithm for
the case p is not too small. magnitude of the choice number of random grap

f locally sparse graphs and to several interesting facts about finite field
