AbstractThe expose-and-merge paradigm for exploring random graphs is presented. An algorithm of complexitynO(logn) is described and used to show that the chromatic number of a random graph for any edge probability 0<p<1 falls in the interval
$$\left[ {\left( {\frac{1}{2} - \varepsilon } \right)\log (1/(1 - p))\frac{n}{{\log n}}, \left( {\frac{2}{3} + \varepsilon } \right)\log (1/(1 - p))\frac{n}{{\log n}}} \right]$$
with probability approaching unity asn→∞.
