This algorithm routes edges organically to ensure that edges do not overlap nodes and keep a specifiable minimal distance between them. It is especially well-suited for non-orthogonal, organic or cyclic layout styles.
The algorithm is based on a force directed layout paradigm. Nodes act as repulsive forces on edges in order to guarantee a certain minimal distance between nodes and edges. Edges themselves tend to contract themselves. Using simulated-annealing this leads to edge layouts, which are calculated for each edge separately. This algorithm will only work correctly if there already is enough room between each pair of nodes in the whole graph, i.e. there should be at least three times the minimal distance room between two nodes.
Route Selected Edges Only
If this option is activated only selected edges will be considered for rerouting.
This specifies the minimal allowed distance between nodes and edges.
Use Existing Bends
This option specifies whether existing bends should be used as an initial solution for the new routing.
Route Only Necessary
If this option is activated only edges that violate the minimal distance criterion will be rerouted.
