Indeed, the bipartite dimension is NP-hard to approximate within | V | 1 / 3 − ϵ {\displaystyle |V|^{1/3-\epsilon }} for every fixed ϵ > 0 {\displaystyle \epsilon >0} , already for bipartite graphs (Gruber & Holzer 2007).
Zaista, bipartitnu dimenziju je NP-težak približio unutar | V | 1 / 3 − ϵ {\displaystyle |V|^{1/3-\epsilon }} za svako ustaljeno ϵ > 0 {\displaystyle \epsilon >0} , već za bipartitne grafove (Gruber & Holzer 2007).
