In the Intervalizing Coloured Graphs problem, one must decide for a given graph G = (V, E) with a proper vertex colouring of G whether G is the subgraph of a properly coloured interval graph. For the case that the number of colors is fixed, we give an exact algorithm that uses (Formula Presented.) time. We also give an (Formula Presented.) algorithm for the case that the number of colors is not fixed.
