M = (Q, Σ, δ, q0, F) accepts a string w = w1 w2 w3 …wn ε Σ*if ∃ a sequence r0, r1, r2,…, rn of states for which–r0 = q0–δ(ri, wi+1) = ri+1 for i = 0, 1, 2, …, n-1–rn ∈ F
Explain in detail about Homology Modelling
Let s1 and s2 be two strings of lengths m and n respectively. By definition, a superstring of s1 and s2 is one which contains s1 and s2 as substrings. Give a dynamic programming algorithm to compute a shortest superstring of t
