β¦ Synopsis
Let n be a large integer and A be a subset of [n] = {1, . . . , n}. The set S A is the collection of the subset sums of A. In this note, we discuss new results (and proofs) on few well-known problems concerning S A . In particular, we improve an estimate of Alon and ErdΕs concerning monochromatic representations.

Lipkin, E., On subset sums of r-sets, Discrete Mathematics 114 (1993) 3677377. A finite set of distinct integers is called an r-set if it contains at least r elements not divisible by 4 for each 4 > 2. Let f(n, r) denote the maximum cardinality of an r-set A c (1,2, , n} having no subset sum Caiai
In the well-known Subset Sum Problem, we are given positive integers a,, , a, and t and are to determine if some subset of the ai sums to t. We investigate the boundary between easy and hard variations of this problem. In particular, we consider the cases where the sequence 'A,~ .L' a,, \_\_\_ ,an i
## Abstract A (__w__,__r__) __coverβfree family__ is a family of subsets of a finite set such that no intersection of __w__ members of the family is covered by a union of __r__ others. A (__w__,__r__) __superimposed code__ is the incidence matrix of such a family. Such a family also arises in crypt
