Practical Problems based on the subject MBI 303: Advanced Algorithms Page 1 of 1Fuzzy LogicSr. No. Definition App. Marks1 Consider the set of old people O. The graded membership M of a 5-8 person X to determine whether the person belongs to old class O or not is defined as follows: M= 0 if age of X is > 0 years and <= 59 years M= (age of X -60)/20 if age of X is > 59 years and <= 79 years M= 1 if age of X is > 79 years Write a computer program using language of your choice which input age of a person X in total years and outputs graded membership.Solution Algorithm: 1. Start. 2. Input the age of a person. 3. Store the age to a variable x. 4. Let the membership we want to calculate is m. 5. If x is between 0 and 59 then m is 0; 6. Else if x is between 60 and 70 then m is ….formula given the membership function; 7. Else m =1. 8. Print age x as well as membership value m. 9. Stop. Program #include<iostream.h> void main() { int x; float m; cout << " Input the age of the person: "; cin >>x; if (x > 0 && x<= 59) { m=0; }

The graded membership M of a 5-8 person X to determine whether the person belongs to old class O or not is defined as follows: M= 0 if age of X is > 0 years and <= 59 years M= (age of X -60)/20 if age of X is > 59 years and <= 79 years M= 1 if age of X is > 79 years Write a computer program using language of your choice which input the graded membership to a person X and outputs broad category of the age of the person X.3 Consider the set of old people O. The graded membership M of a person X to determine whether the person belongs to old class O or not is defined as follows: M= 0 if age of X is > 0 years and <= 59 years M= (age of X -60)/20 if age of X is > 59 years and <= 79 years M= 1 if age of X is > 79 years Write a computer program using language of your choice that returns complement membership of the above set. The input to the program is age of a person x and output is the complement of the graded membership to a person X between the closed interval [0,1].4 Consider the set of machines, M, and the set of people, P, defined as 8-10 follows: M = { set of all machines in a domain} e.g., M = { m1, m2, m3…, mn} where n =3

Also list the ideal machine for each person where the person is most comfortable.5 Consider U = V = {1,2,3}. The relationship R of U*V, defined as 8-10 “approximately equal,” is a binary fuzzy relationship given by 1/(1,1), 1/(2,2), 1/(3,3), 0.8/(1,2), 0.8/(2,3), 0.8/(2,1), 0.4/(1,3), 0.8/(3,2) and 0.4/(3,1). Consider another relationship, S, of U*V in which x is considerably larger than y for ∀x∈U and ∀y∈V. The relationship S can be given as X/Y 1 2 3 1 0 0.6 0.8 2 0.6 0 0.6 3 0.8 0.6 0 Find and print (i) μR∩S(x,y) and (ii) μR∪S(x,y)6 Develop a computer program which prints a menu on clears screen as 20 follows:

The program while execution should ask the users for his/her choice and perform function accordingly. If user gives invalid choice the program should print appropriate message. The program should be terminated only if the choice # 6 (Exit) is given by the user.
