  • Method Details

    • getSepset

      public Set<Node> getSepset(Node i, Node k)
      Retrieves the separation set (sepset) between two nodes.
      Specified by:
      getSepset in interface SepsetProducer
      Parameters:
      i - The first node
      k - The second node
      Returns:
      The set of nodes that form the sepset between node i and node k, or null if no sepset exists

    • getSepsetContaining

      public Set<Node> getSepsetContaining(Node i, Node k, Set<Node> s)
      Retrieves the separation set (sepset) between two nodes i and k that contains a given set of nodes s. If there is no required set of nodes, pass null for the set.
      Specified by:
      getSepsetContaining in interface SepsetProducer
      Parameters:
      i - The first node
      k - The second node
      s - The set of nodes to be contained in the sepset
      Returns:
      The set of nodes that form the sepset between node i and node k and contains all nodes from set s, or null if no sepset exists
