In this paper we take a different direction and consider the numbers of given sum subsets taken from arbitrary multi-sets A ⊆ Zd p. We show that when the size of A exceed...On the number of subsequences with given sum[J] . Weidong Gao.Discrete Mathematics . 1999 (1)...
摘要: Let G be an additive finite abelian p-group. For a given (long) sequence S in G and some element g ∈ G, we investigate the number of subsequences of S which have sum g. This refines some classical results of J.E. Olson and recent results of I. Koutis....
Capacity of an aircraft is K, you have N people with weights Wi. Find minimum number of air-crafts to transport all these people. n <= 10^5 and k <= 10^9 How to approach this problem.
内容提示: arXiv:1811.05793v1 [math.CO] 13 Nov 2018ON THE NUMBER OF SETS WITH A GIVEN DOUBLINGCONSTANTMARCELO SOARES CAMPOSAbstract. We study the number of s-element subsets J of a given abelian group G,such that |J + J| ≤ K|J|. Proving a conjecture of Alon, Balogh, Morris and ...
HYPERGRAPHS WITH MANY COLORINGS 5 For a constant ε > 0, we say that the k-tuple (V1, . . . , Vk) of mutually disjoint subsets V1, . . . , Vk ⊆ V (H) is ε-regular, if there exists a constant d ≥ 0, such that |dH (W1, . . . , Wk) − d| ≤ε for all ...

Answer to: Calculate the number of subsets and the number of proper subsets for the set. The set of natural numbers less than 10. A) 511; 510 B)...
6=2⋅3 is a divisor of 60=22⋅3⋅5 . So we only need to find all different subsets of the prime factorization of n .Usually the number of subsets is 2x for a set with x elements. However this is no longer true, if there...
Let a finite set R with n elements be given. A system $\alpha = \{ A_1 , \cdots ,A_r \} $ of r subsets of the set R for which $A_i A_j = \emptyset $ and $\sum A_i = R$ is called a decomposition of R. One says that two decompositions $\alpha = \{ A_i , \...
