Using FindRank() and GetByRankRange() together you can show users with a score similar to a given user. All very quickly. Documentation https://godoc.org/github.com/wangjia184/sortedsetAbout An ordered collection implemented in Golang with O(log(N)) time complexity on adding / searching ...
The main goal of this paper is proposing an efficient algorithm to compute the width of a given partially ordered set P according to Dilworth's theorem. It is an efficient and simple algorithm. The time complexity of this algorithm is O (kn), such that n is the number of elements of ...

However, this structure is not extensible: if the number of elements grows beyond the predetermined size, the time complexity of operations will no longer be constant. Michael [2002a] 以 Harris [2001] 的工作为基础,提供了一种有效的基于 compare-and-swap (CAS) 的无锁链表算法(我们将在下一节...

Can the algorithm used by Gilenson & Shabtay (2021) for the 1|S,pj(i),wj(i)|∑i=1qθiG(i) problem be modified to solve, in polynomial time, the more general 1|S,pj(i),wj(i)|SO(G(i))i=1q problem? • What is the complexity status of problems 1|S,wj(i)|(G(i))i...
With an OT system, adding more operations increases implementation complexity quadratically since every operation must transform correctly past every other operation.Fractional IndexingInstead of OT, Figma uses a trick that’s often used to implement reordering on top of a database. Every object has ...
The best case and the average case complexity for all the operations in an unordered_map is O(1). While in the worst case, the time complexity for all the operations in an unordered_map is O(n). The difference between an unordered_map and an unordered_set is that an unordered_map sto...
A fast algorithm for computing the NCHT is also developed using sparse matrix factorization and its computational complexity is examined. Introduction Discrete orthogonal transforms have been used extensively in control and communication theories, and digital signal processing. The commonly used orthogonal ...
