Many MSA tools and genetic alignment algorithms have parameter values either as default or optional making it difficult to select appropriate method and parameter values since the sequence is unknown. A global multiple sequence alignment algorithm (SOGA) includes 2 new operators which perform a self organizing crossover and mutation operation for the required number of generations. Another algorithm (SOSW) performs pairwise alignment and progressively aligns it to a local multiple sequence alignment (MSA) based on the alignment score. The proposed algorithms select appropriate alignment and parameter values based on sequence length, identity and alignment score, reducing time to optimize parameter values and prevent execution with default values. A score columm then compares alignment to validate results.


Key Words: Algorithm, sequence alignment.
