Recall that we discussed the "leader-based" deterministic distributed algorithm for 2-colouring a path, that runs in time O(n) on an n node path network. Suppose we now relax the constraint of 2-colouring to mean, it is okay for one of the neighbours of a node to x get the same colour as the mode x, as long as the other neighbour gets a different colour. The end points must get a different colour from their respective unique neighbours. The running time for a best efficiency deterministic distributed algorithm, using unique identifiers for nodes, for this problem would be:
