*point-interval*$$(I_v, p_v)$$ ( I v , p v ) is a pair constituted by an interval $$I_v$$ I v of $${\mathbb {R}}$$ R and a point $$p_v \in I_v$$ p v ∈ I v . A graph $$G=(V,E)$$ G = ( V , E ) is a Max-Point-Tolerance (MPT) graph if each vertex $$v\in V$$ v ∈ V can be mapped to a point-interval in such a way that (
