Whether to constrain most edges to point downwards

type: string | bool, default: false

If true, constraints are generated for each edge in the largest (heuristic) directed acyclic subgraph such that the edge must point downwards.

Only valid when mode="ipsep".

If hier, generates level constraints similar to those used with mode="hier". The main difference is that, in the latter case, only these constraints are involved, so a faster solver can be used.

Valid on:
  • Graphs

Note: neato only.
