Description

Globally optimal Bayesian network learning using integer linear programming (GOBNILP) is a score based method using integer linear programming (ILP) for learning an optimal DAG for a Bayesian network with limit on the maximal number of parents for each node. It is a two-stage approach where candidate parent sets for each node are discovered in the first phase and the optimal sets are determined in a second phase.

Important

This module only works on the AMD64 architecture.

Some fields described

constraints File with constraints to pass to the solver. The file should be placed in resources/constraints and the format is the same as used by gobnilp (see the docs).
extra_args File with extra arguments to pass to the solver. The file should be placed in resources/extra_args and the format is the same as used by gobnilp (see the docs).
gap_limit Gap limit.
time_limit Time limit in seconds for the solver (not including the time to build the score tables).
timeout Use the best DAG found so far after this number of seconds.
