This thing actually means multiplication ( I am assuming "scale" takes a numerical value)(x - 1) (scale - 1)
i have this function, but my maths is less than bad
the function is
fitness of x = scale - ( 2 * (x - 1) (scale - 1) / noIndiviuals - 1 )
my question is what do i do with the (x - 1) (scale - 1) part
do i add them together or multiply them together?
