diredgeconstraints
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.
