β¦ Synopsis
Let F h (N) be the maximum number of elements that can be selected from the set [1, ..., N] such that all the sums a 1 + } } } +a h , a 1 } } } a h are different. We introduce new combinatorial and analytic ideas to prove new upper bounds for F h (N). In particular we prove
Besides, our techniques have an independent interest for further research in additive number theory.

The unweighted Maximum Satisfiability problem MAXSAT is: Given a Boolean formula in conjunctive normal form, find a truth assignment that satisfies the largest number of clauses. This paper describes exact algorithms that provide new Ε½< < upper bounds for MAXSAT. We prove that MAXSAT can be solved i
The Ramsey number R(G 1 , G 2 ) is the smallest integer p such that for any graph Some new upper bound formulas are obtained for R(G 1 , G 2 ) and R(m, n), and we derive some new upper bounds for Ramsey numbers here.
We show that the maximum size of a B 2 -sequence of binary n-vectors for large enough n is at most 2 0.5753n , thus improving on the previous bound 2 0.6n due to B. Lindstro m.
We introduce a new counting method to deal with B 2 [2] sequences, getting a new upper bound for the size of these sequences, F(N, 2) -6N+1.
