A picture of common subsequence length for two random strings over an alphabet of 4 symbols

Free access

The maximal length of longest common subsequence (LCS) for a couple of random finite sequences over an alphabet of 4 characters was considered as a random function of the sequences lengths and 𝑛; Exact probability distributions tables are presented for all couples of length in a range 2
