Assuming a directed network 4, in which we can draw two different edges between two nodes, both indicating the direction (from 1 to 2, or from 2 to 1, as in a one-way street), we have 14 edges (2 × 7) in the first and 18 edges (2 × 9) in the second network (see also Table 4, where the original matrices are given).

We can consider the structure of intratype interaction as an undirected network where each player represents a node and there is a link between two nodes if both players can play the intratype game (i.e. they are spatial neighbours and they have the same tag).
The nodes of the graph G correspond to the elements of U and there is an edge between two nodes if both l-mers are contained in a same read.
Cleavable bonds are represented as nodes in an undirected graph, with an edge between two nodes if both bonds can be cut; we note that not all bonds that match the rules can be cleaved at the same time, because doing so would yield fragments smaller than the minimum size.
A node is introduced for each evidence of deletion site and an edge between two nodes signifies that both nodes can be explained by the same deletion; formally, let v i, j denote the vertex associated with row i and column j, then v i, j ∈ V if M′ i, j =1 and (v i, j, v k, l )∈ E if the ranges [ M′ i, j, M′ i, l ] and [ M′ k, l, M′ k, j ] contain no X.
However, NTP assumes that the transmission delay between two nodes is the same in both directions.
Entities may flow along both directions between two nodes connected by an undirected edge [10, 11, 13].
Nevertheless, how to choose a path between two nodes in a network relies on both performance and security considerations.
Where the transition occurs in both directions between two nodes, two directed links (one in each direction) are used.
Nodes represent families, links between two nodes are associations with offspring common to both families.
The number of shared neighbours between two nodes is the number of nodes that are neighbours of both of them.

Since I tried Ludwig back in 2017, I have been constantly using it in both editing and translation. Ever since, I suggest it to my translators at ProSciEditing.
