In this paper we introduce a family of integer polytopes and character
ize them in terms of forbidden submatrices. The two extreme cases in t
his family arise when the constraint matrix is totally unimodular and
balanced, respectively. This generalizes results of Truemper-Chandrase
karan and Conforti-Cornuejols.
