This commit adds the new function
:func:graphix.random_objects.rand_og_gflowwhich generates random open graphs with gflow. In particular:n.n <= n_o.The function implements the PGA algorithm [1] which guarantees that any open graph can be generated.
Additional comments
The module
graphix.random_objectsis not type-safe (although the functions introduced in this PR are). It could also benefit from some cleansing and refactoring, but I guess it's not a priority.References
