I am trying to find combinations of elements of a vector whose sum is greater or equal to a given value. For example: vec = [5 4 3 2 1]; criteria = 8.5; Then the output would look like [5 4] [5 3 2] [5 3 1] [4 3 2] ...
We used a computer to exhaustively handle all the possible candidates formed by the subset of 304 脳 5074 = 1542496 combinations with Ai < 3003344 + 106 = 4003344. This revealed that a(6) = 3003344034004 is the smallest number in base 10 that cannot be collapsed using fewer than 6 plus ...
