Talk:Nowhere-zero flow

poorly defined
The flow/coloring duality 'algorithm' is very poorly defined. Consider the 4-cycle. The flow required is simple to see, but using the left/right argument leads to great ambiguity. I don't know the standard argument off hand, but as it is written, it is not well defined. Maybe just reference the 1954 result due to Tutte that says exactly that result.
 * What ambiguity? Because it's a directed graph, left/right is well determined. —David Eppstein (talk) 17:10, 18 November 2011 (UTC)

Not vital
The banner above identifies this as a vital article, but surely it cannot possibly be that. 67.198.37.16 (talk) 22:06, 5 June 2021 (UTC)
 * Whatever. I removed it. Someone was hallucinating. 67.198.37.16 (talk) 22:08, 5 June 2021 (UTC)
