We consider the problem of aligning of k sequences of length n. The cost function is sum of pairs, and satisfies triangle inequality. Earlier results on finding approximation algorithms for this problem are due to Gusfield (1991) who achieved an approximation ratio of 2 -2/k, and Pevzner (1992) who
