A conjecture of Erdős, Gyárfás, and Pyber says that the vertices of any r-edge-coloured complete graph can be covered by r vertex-disjoint monochromatic cycles. This conjecture was proved for r = 2, but turned out to be false for r at least 3. However there remain various weaker versions of the conjecture which may still hold. I will discuss how to prove a 3-colour version of it when one wants to cover the graph by paths instead of cycles.
