Answer:
B. The cost of tour t is at most twice the cost of the optimal tour.
Explanation:
You are using a polynomial time 2-approximation algorithm to find a tour t for the traveling salesman problem.
The cost of tour t is at most twice the cost of the optimal tour
The equation represented as Cost(t) <= 2 Cost(T)
Where
Cost (t) represents cost of tour t
Cost(T) represents cost of the optimal tour
Answer: It arranges text in a list alphabetically from A to Z.
Explanation: It's always easier and more systematic to arrange alphabetically. With numbers there is the possibility of infinity but not with alphabet which have a defined range.
Answer:
A AND B= 1 or 0
1 1 1
0 1 0
1 0 0
0 0 0
So, as explained above if both are 1 we then only get 1, or else we get 0 always in case of AND which is a logical operator, whose output can be 0 or 1 only. This is being depicted above.
Explanation:
If both are 1 we get 1 or always else, we get the output =0.
