AbstractRdl and Rucinski have extended Ramseys Theorem to random graphs, showing that there is aconstant C' such that with high probability, any two-colouring of the edges of G(n, p) with edgeprobability p= C'n?/(t+1) contains a monochromatic copy of Kt (the complete t-vertex graph). Weinvestigate how this statement extends to arbitrary colourings of G(n,p). Namely, when noassumptions are made ...
