An online article in 2001 described a study in which twelve sixth-grade students who had not previously played chess participate

d in a program where they took chess lessons and played chess daily for 9 months. Each student took a memory test (the Test of Cognitive Skills) before starting the chess program and again at the end of the 9 month period. Data and computed differences are given in the accompanying table. The author of the article proposed using these data to test the theory that students who participated in the chess program tend to achieve higher memory scores after completion of the program.

The number of operations executed by algorithms A and B is 40n2 and 2n3, respectively. Determine n0 such that A is better than B
Tom [10]

Answer:

Given that:

A= 40n^2

B = 2n^3

By given scenario:

40n^2=2n^3

dividing both sides by 2

20n^2=n^3

dividing both sides by n^2 we get

20 = n

Now putting n=20 in algorithms A and B:

A=40n^2

= 40 (20)^2

= 40 * (400)

A= 16000

B= 2n^3

= 2 (20)^3

= 2(8000)

B= 16000

Now as A and B got same on n = 20, then as given:

n0 <20 for n =20

Let us take n0 = 19, it will prove A is better than B.

We can also match the respective graphs of algorithms of A and B to see which one leads and which one lags, before they cross at n= 20.
