Parallel Transitive Closure Algorithm for Heterogeneous Architecture [PDF]
Jisuanji gongcheng, 2021 The traditional method for obtaining the transitive closure of the graphs faces the large amount of calculation and long calculation time. In order to improve the computing speed of the transitive closure algorithm for dealing with large amounts of data,

Reconstruction Method of Ocean Front Model Based on Fuzzy Cluster Analysis of Sound Speed Profile
IEEE Access, 2021 Ocean fronts are mostly determined according to the horizontal temperature gradient, and various selection criteria may lead to different frontal zones. This study proposes a frontal zone delineation method based on sound speed profile.

L-Recursion and a new Logic for Logarithmic Space [PDF]
Logical Methods in Computer Science, 2013 We extend first-order logic with counting by a new operator that allows it to formalise a limited form of recursion which can be evaluated in logarithmic space.

Characterization of Transitivity in L-Tolerance Spaces by Convergence and Closure
Axioms, 2021 We show that the category of quantale-valued tolerance spaces is isomorphic to a category of quantale-valued convergence spaces. We define suitable quantale-valued closure functions and use them to characterize transitivity axioms.

A survey of parallel execution strategies for transitive closure and logic programs [PDF]
, 1993 An important feature of database technology of the nineties is the use of parallelism for speeding up the execution of complex queries. This technology is being tested in several experimental database architectures and a few commercial systems for ...

On the Cost of Transitive Closures in Relational Databases [PDF]
, 1993 We consider the question of taking transitive closures on top of pure relational systems (Sybase and Ingres in this case). We developed three kinds of transitive closure programs, one using a stored procedure to simulate a built-in transitive closure ...

Dual digraphs of finite semidistributive lattices
Cubo, 2022 Dual digraphs of finite join-semidistributive lattices, meet-semidistributive lattices and semidistributive lattices are characterised. The vertices of the dual digraphs are maximal disjoint filter-ideal pairs of the lattice.

Data fragmentation for parallel transitive closure strategies [PDF]
, 1993 Addresses the problem of fragmenting a relation to make the parallel computation of the transitive closure efficient, based on the disconnection set approach. To better understand this design problem, the authors focus on transportation networks.

Transitive Closures of Ternary Fuzzy Relations
International Journal of Computational Intelligence Systems, 2021 Recently, we have introduced six types of composition of ternary fuzzy relations. These compositions are close in spirit to the composition of binary fuzzy relations.
