Here in sweden there are currently circulating some email with a challange about solving a math puzzle.
It’s nothing special really but the mail goes something like this (translated):
(Don’t blame me for the claims in the quote, it’s not my words)
It’s said that only people with an IQ over 120 can solve the following problem:
If we assume that:
2 + 3 = 10
7 + 2 = 63
6 + 5 = 66
8 + 4 = 96
How much is?
9 + 7 = ????
The mail contains an excel file with a password and can only be opened if you know the answer to the above.
Just for the hell of it I entered the problem into my old genetic expression evolver:
The application is based on genetic programming and does use genetic crossover and a real population (unlike my EvoLisa sample).
The problem was described like this:
problem.Cases.Add(new Case(2, 3, 10));
problem.Cases.Add(new Case(7, 2, 63));
problem.Cases.Add(new Case(6, 5, 66));
problem.Cases.Add(new Case(8, 4, 96));
The first and second arguments are variable values and the last argument is the expected output.
And here is the output of the application:
As you can see on the screenshot, the application have solved the equation in 250 generations (a few milliseconds).
That’s probably faster than you solved it ;-)
If it makes you feel better, I didn’t solve it at all, I go into fetus position on the floor when I see math problems ;-)
