beta
- The parameter defining the "softness" of the alignment. For
beta towards infinity this alignment becomes closer to the strict
alignment. For beta = 0 all possible alignments are equally considered
and softmin returns the average. Please note that a low beta value might
lead to a very rough approximation and that for higher sequence lengths
beta has to be higher, too.public double getBeta()
