This paper attaches a frame to a natural class of combinatorial problems and points out that this class includes many important special cases. A matrix M is said to avoid a set~ of matrices if M does not contain any element of.~" as (ordered) submatrix. F or.~ a fixed set of matrices, we consider the pmbiem of deciding whether the rows and columns of a matrix can he permuted in such a way that the resulting matrix M avoids all matrices in.~'.We survey several known and new results on the algorithmic complexity of this problem, mostly dealing with (0, l)-matrices. Among others, we will prove that the problem is polynomial time solvable for many sets." containing a single, small matrix and we will exhibit some example sets~ for which the problem is NP-complete.
