....which avoids X 4 has the consecutive ones property in columns. Gus eld [11, Theorem 3] has proven that a matrix which has a phylogenetic tree can be reordered so as to satisfy that property. In fact, the reordering used by Gus eld s proof generates an essentially canonical matrix. Klinz et al. [16] study and review numerous problems of permuting matrices to avoid forbidden submatrices. 4 The Algorithm Let A be the input matrix. De ne G x (A) S; C; E A x ) for x = 1. For a subset ; 6= S 0 S, we say that a character is S 0 semi universal in A if its 0 set does not intersect ....

.... a graph is an X graph if and only if there exists an enumeration of its vertices such that its adjacency matrix avoids the two submatrices X 1 = 0 1 1 1 and X 2 = 0 1 1 0 : Further results on 0 1 matrices which avoid forbidden submatrices are given in Klinz, Rudolf and Woeginger [9]. Also the class of Monge matrices can be embedded in our framework and characterized via forbidden 2 Theta 2 submatrices. An n Theta n matrix C is called a Monge matrix , if C fulfills c ij c rs c is c rj for 1 i r n; 1 j s n: 1) Monge matrices play an essential role in discrete ....

....Zaporozhets [67] While on the one hand it follows from the observations above that there are infinitely many Monge matrices, on the other hand the number of Monge matrices with small entries and distinct columns and distinct rows is rather small. More precisely, Klinz, Rudolf and Woeginger [86] have shown that a 0 1 Monge matrix C with no identical rows and columns is of order at most 4 Theta 3 or 3 Theta 4. This result carries over to Monge matrices with two different entries. Using similar arguments it can be shown that a Monge matrix with entries from the set f0; 1; kg and ....
