set how to check for large dags
The default settings is set to error if the graph is too large. If you modify this, the layout may run forever, or may crash. See OptChecking for more details.
(default: "fast")
get the current check for large graphs
set whether to also minimize distance between nodes that share an ancestor
This setting adds more variables and constraints, and so will make the decrossing step take longer, but will likely produce a better layout as nodes that share common parents or children will be put closer together if it doesn't affect the number of crossings. It is especially usefuly for ancestry layoutss where nodes that share a child will inherently be put closer together even if it doesn't reduce the number of crossings.
(default: false)
get whether the current layout minimized distance
a Decross that minimizes the number of crossings
This method brute forces an NP-Complete problem, and as such may run for an exceedingly long time on large graphs. As a result, any graph that is probably too large will throw an error instead of running. Use with care.
