A block of consecutive ones (bco for short) in a binary m× n-matrix is any maximal sequence
of consecutive ones occurring in the same row. We consider the Consecutive Block …

Abstract A binary matrix MM has the Consecutive Ones Property (COP) if there exists a
permutation of columns that arranges the ones consecutively in all the rows. We consider …

A binary matrix has the Consecutive Ones Property (C1P) if there exists a permutation of its
columns (ie a sequence of column swap**s) such that in the resulting matrix the 1s are …

A binary matrix M has the Consecutive Ones Property (COP) if there exists a permutation of
columns that arranges the ones consecutively in all the rows. We consider the …

F. Wehrung has asked: Given a family CC of subsets of a set Ω, under what conditions will
there exist a total ordering on Ω with respect to which every member of CC is convex?¶ We …

Abstract We investigate (0, 1)-matrices that are convex, which means that the ones are
consecutive in every row and column. These matrices occur in discrete tomography. The …

A binary matrix $ M $ has the Consecutive Ones Property (COP) if there exists a permutation
of columns that arranges the ones consecutively in all the rows. Given a matrix, the $ d …

We consider the following Constraint Satisfaction Problem: Given a set C of constraints in
which each constraint has a subset of Variables V that maps to the set of nodes N (T) of a …

The main topics of this manuscript are sparsity and discrimination for modeling complex
data. In a first part, we focus on the GMM context: we introduce a new family of probabilistic …

A set {a, b, c, d, e, f, g, h, i, j, k} of n students arrive for a summer course. They form m study
groups {R, B, O, G}. A student is in at least one study group, R={g, h, i, j, k}, B={a, b, e, g} …
