A monotone path in an edge-ordered graph
An edge-ordered graph is an ordered pair (G,f), where G is a graph and f is a bijective function, f:E(G)→{1,2,…,|E(G)|}. A monotone path of length k in (G,f) is a simple path Pk+1:v1v2…vk+1 in G such that either f({vi,vi+1})<f({vi+1,vi+2}) or f({vi,vi+1})>f({vi+1,vi}) for i=1,2,…,k−1....

An edge-ordered graph is an ordered pair (G,f), where G is a graph and f is a bijective function, f:E(G)→{1,2,…,|E(G)|}. A monotone path of length k in (G,f) is a simple path Pk+1:v1v2…vk+1 in G such that either f({vi,vi+1})<f({vi+1,vi+2}) or f({vi,vi+1})>f({vi+1,vi}) for i=1,2,…,k−1. |
