Given a matrix, the $d$-COS-R problem is to determine if there exists a set of at most $d$ rows whose deletion results in a matrix with COP. We consider the parameterized complexity of this problem with respect to the number $d$ of rows to be deleted as the parameter. The closely related Interval Deletion problem has recently shown to be FPT [Y. Cao and D. Marx, Interval Deletion is Fixed-Parameter Tractable, arXiv:1211.5933 [cs.DS],2012].
