A path may follow a single edge directly between two vertices, or it may follow multiple edges through multiple vertices.
For example, Larsen and co observed a star structure with a central node and multiple inbound edges.
That is, we allow multiple edges (edges with the same pair of endpoints) and loops (edges whose two endpoints are the same vertex).
These patterns clearly support additive models of edge effects [28], which suggest that the intensity of edge phenomena is compounded by multiple nearby edges.
A vertex with multiple incoming edges and, therefore, multiple parents, is constructed using substrings of all of the parent blocks.
These are represented as nodes with multiple incoming edges in the ARG.
Miller and Page note that "there are multiple edges, not just a single one" (Miller and Page 2007, p. 133).
Multiple edges ending at a composite node are conditionally dependent on each other, and multiple edges ending at an original node or complementary node are independent.
What about multiple edges between vertices?
Adds multiple edges to the polygon whose components are given by the displacements dx and dy from the last vertex.
