WebIn the mathematical area of graph theory, a chordal graph is one in which all cycles of four or more vertices have a chord, which is an edge that is not part of the cycle but connects two vertices of the cycle. Equivalently, every induced cycle in the graph should have exactly three vertices. The chordal graphs may also be characterized as the ... WebDec 16, 2024 · We have cyclic directed graph (possibly disconnected). For cycles consisting of two vertices A->B and B->A, we replace them by a single vertex. In case of A->B, B->C, C->A we also replace them by one vertex. We replace N vertices when all reachable from each other. Edges leaving a vertex stay as edges leaving the group … b in the know https://fchca.org
