WebIt is well-known that there are instances of the binary paint shop problem for which the recursive greedy heuristic is better than the greedy heuristic. In this note, we give an example of a family of instances where the greedy heuristic is better than the recursive greedy heuristic, thus showing that these heuristics are uncorrelated.
