Help with alignments with discovery studio!

Hello,

i am an academic student studying at the university of hertfordshire, i am carrying out my dissertation on molecular modelling and have recently downloaded discovery studio visualiser 2.5.5. I am fairly new to this type of software and was wondering if anybody could help me with the following:

1) what algorithm does this software use to create pairwise alignments?

2) what matrices are involved in doing so?

any help and guidance
