Hirschberg gave an alignment algorithm for the longest common subsequence problem that uses O( n 2 ) time and O( n ) space for two strings of length ~ n . A simple modification of the algorithm can sample string alignments at random according to their probability distribution. This is ...
In general, this will mean that containers that behave like String or Array will perform best. History¶ ↑ Diff::LCS is a port of Perl’s Algorithm::Diff that uses the McIlroy-Hunt longest common subsequence (LCS) algorithm to compute intelligent differences between two sequenced enumerable...
