This paper considers the following optimization problem: Given positive integers n, B, @a"i and nondecreasing functions C"i(.) for i = 1, 2, ..., n, find z = (z"1, z"2...z"n) such that 0== B and @S"i"="1^nC"i(z"i) is the minimum possible. A fully polynomial approximation scheme for this problem is presented.
