We compute theLongest Common Compatible Extensionof each pair of positions(i,j)in a partial word, i.e., the longest substrings starting atiandjthat arecompatiblevia a combinatorial approach. We also estimate the LCCE of each pair of positions in a partial word via a probabilistic approach. ...
the Longest CommonSubsequences in Random Words With an Omitted LetterChristian Houdré ∗ Qingqing Liu †December 27, 2018AbstractWe investigate the variance of the length of the longest common subsequences of two inde-pendent random words of size n, where the letters of one word are i.i.d...

k-Ary wordAlternating sequenceGenerating functionRecently, Stanley [Longest alternating subsequences of permutations, preprint, arXiv/0511419v1] studied the length of the longest alternating subsequence of a permutation in the symmetric group, where a sequence a , b , c , d , … is alternating ...
In such a repeat (palindrome) $u$ is called the arm of the repeat (respectively, palindrome), while $v$ is called the gap. We show how to compute efficiently, for every position $i$ of the word $w$, the longest gapped repeat and palindrome occurring at that position, provided that ...
