In this paper we consider problems related to the sortedness of a data stream. First we investigate the problem of estimating the distance to monotonicity; given a sequence of len...
—We investigate the k-LCS problem that is finding a longest common subsequence (LCS) for k given input strings. The problem is known to have practical solutions for k = 2, but f...

In this paper, we present algorithms and lower bounds for the Longest Increasing Subsequence (LIS) and Longest Common Subsequence (LCS) problems in the data streaming model. For t...
In [1], Murata et al introduced an elegant representation of block placement called sequence pair. All block placement algorithms which are based on sequence pairs use simulated a...
We study the problem of, given two sequences x and y over a finite alphabet, finding a repetitionfree longest common subsequence of x and y. We show several algorithmic results, a...
