Polynomial-time approximation algorithms for weighted LCS problem

We consider a variant of the well-known Longest Common Subsequence (LCS) problem for weighted sequences. A weighted sequence determines the probability for each symbol to occur at a given position of the sequence (such sequences are also called Position Weighted Matrices, PWM). Two possible such ver...
