AbstractA {0, 1} matrix U is defined to be complement totally unimodular (c.t.u.) if U as well as all matrices derived from U by certain complement operations are totally unimodular. Two decompositions of minimal violation matrices of total unimodularity are utilized to characterize the letter matrices by c.t.u. matrices. In addition properties of c.t.u. matrices are presented
