incidence_treewidth (430B)


      1 # Incidence treewidth
      2 
      3 [treewidth] of [incidence_graph] of [conjunctive_normal_form] [boolean_formula]
      4 
      5 more general than [primal_treewidth], by [szeider2003fixed]
      6 - bounding [primal_treewidth] implies a bound on the [incidence_treewidth]
      7   - specifically [incidence_treewidth] is \leq [primal_treewidth] + 1
      8     - lemma 4 of [szeider2003fixed]
      9 - but not vice-versa
