What dose this function mean and what is the differentes ?

function u = heuristic0(B)
u = sum(B(:) == 0); %the number of bricks that are zero
end




function u = heuristic1(B)
u  =  - sum(B(:));  %the negative sum of the values of the bricks 
                       %(remember they are in logarithm, so its not 
                       % the original values being summed)
end

How would I explain the heuristic function if i combine both of these together?

Answer 1

The first is calculating the number of zeros in B and the second is summing all values in B (times -1).

[DAL]

how would you read this?

u = - sum(B(:) == 1

[Matt J]

You are missing a parenthesis, so the intended code is ambiguous.

[DAL]

u = - sum(B(:) == 1) like this?

I had added this to my AI for 2048 and compared it with the random AI. The result gave that my AI gave a higher score than the random. I wondered how i could explain how they would work together

[Matt J]

That's -N wher N is the number of B(i) that equal 1.

[DAL]

wherest the N is the tiles?
