71.       The map colouring problem can be solved using which of the following technique?
(A) Means-end analysis
(B) Constraint satisfaction
(C) AO* search
72.       Which of the following is a knowledge representation technique used to represent knowledge about stereotype situation?

73.       A fuzzy set A on R is ................. iff A(λx1 + (1 – λ)x2) ≥ min [A(x1), A(x2)] for all x1, x2 R and all λ [0, 1], where min denotes the minimum operator.
(A) Support
(B) α-cut
(C) Convex
(D) Concave
74.       If A and B are two fuzzy sets with membership functions
μA(x) = {0.6, 0.5, 0.1, 0.7, 0.8}
μB(x) = {0.9, 0.2, 0.6, 0.8, 0.5}
Then the value of μ(AB)’(x) will be
(A) {0.9, 0.5, 0.6, 0.8, 0.8}
(B) {0.6, 0.2, 0.1, 0.7, 0.5}
(C) {0.1, 0.5, 0.4, 0.2, 0.2}
(D) {0.1, 0.5, 0.4, 0.2, 0.3}
Explanation:
μ(AB)(x) = max{ μA(x), μB(x)}
μ(AB)’(x) = 1- μ(AB)(x)
75.       Consider a single perception with weights as given in the following figure:

(C) XOR problem
(D) All of the above
