is.conformal {HyperG}

Conformal Hypergraphs

Description

Tests whether a hypergraph is conformal.

Usage

is.conformal(h)
is.bi.conformal(h)

Arguments

h

a hypergraph.

Details

A hypergraph h is conformal if all the maximal cliques of its 2-section are the maximal (by inclusion) edges of h. The test uses a theorem (see the reference, Theorem 7.6.4) that says a hypergraph is conformal if and only if its dual is Helly. A hypergraph is bi-conformal if it and its dual are conformal.

Value

a logical.
