edgebaseret

Edgebaseret is a Danish term used to describe a methodological stance in graph-related disciplines where the primary unit of analysis or computation is the edge rather than the vertex. In practice, edgebaseret approaches model graphs by focusing on the properties and interactions carried by edges, such as weights, directions, capacities, or flow, and compute results by operating on edges and their incident structures. The term appears in Danish-language technical literature and is used across fields such as computer science, network analysis, and image processing, where edge information is central to the problem.

In graph processing, edgebaseret methods may enable efficient updates in dynamic graphs, since changes are often localized to a subset of edges. In image processing, edge-based algorithms leverage boundaries detected by edges to segment or classify regions, in contrast to region-based or pixel-centric methods. In network routing or flow problems, edge-centric models emphasize the constraints and costs on connections between nodes.

The approach often contrasts with vertex-based methods. Edge-based designs can offer advantages in locality and parallelization for certain workloads, but may require different data structures, such as edge-centric adjacency representations, and can be more complex to program.
