hi,

i have a group of items, stored in an array, sorted according to the influence:

say

class person

name (string)

influence (number)

end class

i have a number x, i need to get a group of items where the sum of their influence is the closest to the given number x

example:

s1 70

s2 60

s3 25

s4 11

and x = 90:

so the result wil be s2 and s3 coz 70 + 25 = 95 is the closest sum to 90..

sorry for i dont know if such an algo has a name..

thanks for any help.
