Definition: The problem of finding a maximum length (or maximum weight) subsequence of two or more strings.
Also known as heaviest common subsequence.
See also Ratcliff/Obershelp pattern recognition, longest common substring, shortest common supersequence.
Note: The longest common substring is contiguous, while the longest common subsequence need not be.
