Need help with Algorithm and Dynamic Programming plsssss

based on gap penalty function definition:

w(k)= h + gk, k>0

where h penalizes opening of a gap and is usually large ( -12 or so ), and g penalizes extension of a gap ( usually -2 or -3 )

1- Sketch a Dynamic Programming algorithm for the affine gap penalty case . Just stating the recurrence relations will suffice.

2- Comment of the types of effects on alignments produced if you varied h and g as follows:

h g effect?

large large

small large

large small

Many Thanks,
Rico
