Given two strings X and Y, where X consists of the sequence of symbols X1, X2, Xm and Y consists of the sequence of symbols y₁,Y2, ***,yn. Consider the sets {1, 2, ..., m} and {1, 2, ..., n} as representing the different positions in the strings X and Y, and consider a matching of these sets, where a matching is a set of ordered pairs with the property that each item occurs in at most one pair. A matching M of these two sets is an alignment if there are no "crossing" pairs: if (i,j). (i*,j') = Mandi 0 that defines a gap penalty. For each position of X or Y that is not matched in M (it is a gap), we incur a cost of 8. Second, for each pair of letters p and q (p + q) in our alphabet, there is a mismatch cost of app for lining up p with q. Thus, for each (i,j) = M, we pay the appropriate mismatch cost axiy for lining up x; with y;. The cost of M is the sum of its gap and mismatch costs, and the problem seeks an alignment of minimum cost. Define the minimum alignment cost OPT(i,j) (0 ≤ i ≤…

Design a deterministic finite-state automaton over the alphabet {a; b; c}that accepts words where each character is immediately followed by atleast one identical character.

Write the transition function of the automaton as a table and draw the automaton in the form of a transition diagram. Try to design the simplest possible automaton, i.e., an automaton with the smallest number of states.

Give a description representation of a Turing Machine Mg for language B = {w over {0, 1, #3*| w contains an equal number of O's and 1's and w contains exactly 1 #"}. 10# E B, 01#10 EB, 01##01 € Band #001 € B. In this case, your description should be for a single tape TM. In addressing be sure to pay special attention to final (halting) configurations, when required. you are expected to provide pseudocode for the corresponding machines. Remember that in your pseudocode, you need to be clear of what are your reading and writing on the tape (and which tape if you use more than 1), the direction in which the tape heads will move, and when the Turing Machine should halt and accept and/or halt and reject. Having said that, the point is not for you to describe state-by-state what the Turing Machine would look like. Instead, the goal of the description is for you to offer a high level overview that considers what to read/write in which order, in which directions the tape would move and how you…
