Tractability Results for the Consecutive-Ones Property with Multiplicity
A binary matrix has the Consecutive-Ones Property (C1P) if its columns can be ordered in such a way that all 1’s in each row are consecutive. We consider here a variant of the C1...

Approximation and fixed-parameter algorithms for consecutive ones submatrix problems
We develop an algorithmically useful refinement of a forbidden submatrix characterization of 0/1-matrices fulfilling the Consecutive Ones Property (C1P). This characterization ...

Approximability and Parameterized Complexity of Consecutive Ones Submatrix Problems
Abstract. We develop a refinement of a forbidden submatrix characterization of 0/1-matrices fulfilling the Consecutive Ones Property (C1P). This novel characterization finds app...

Cyclical scheduling and multi-shift scheduling: Complexity and approximation algorithms
We consider the multiple shift scheduling problem modelled as a covering problem. Such problems are characterized by a constraint matrix that has in every column blocks of consecu...

A Shortest Path-Based Approach to the Multileaf Collimator Sequencing Problem
Abstract. The multileaf collimator sequencing problem is an important component in effective cancer treatment delivery. The problem can be formulated as finding a decomposition of...
