(graph theory) A connection between two vertices. Tie A tiewig. Tie (transitive) To twist (a string, rope, or the like) around itself securely. Tie this rope in a knot for me, please. Tie the rope to this tree. Tie (transitive) To form (a knot or the like) in a string or th...
The scan operation is a simple and powerful parallel primitive with a broad range of applications. In this chapter we have explained an efficient implementation of scan using CUDA, which achieves a significant speedup compared to a sequential implementation on a fast CPU, and compared to a ...
(V, E) and a prefix code tree Tprefix, the communication pattern graph Gc = (Vc, Ec) of CG Binomial and TPrefix is a subgraph of CG Binomial. For every (Pi„ Pj) ϵ Ec, Pi and Pj, are in the left and the right subtrees of TPrefix, respectively, and Pi Pj ϵ Vc. ...
node and the system obtains data that defines a respective value for each leaf node; generating a binary tree data structure representing the root node and the other nodes with branches having binary values and connecting the nodes according to the data that defines connections. No valid code is...
The source code of both algorithms is available at https://github.com/felipelouza/apsp. Both our algorithm and OG were compiled by g++ v 4.7.2, with the flag std c++11 and the optimization flags O3, ffast-math, funroll-loops, m64, fomit-frame-pointer and D_FILE_OFFSET_BITS=64. Read...
We present the new concept of prefix-reversal Gray codes based on independent cycles which extends the known greedy prefix-reversal Gray code constructions given by Zaks and Williams. Cases of non-existence of codes based on the presented family of independent cycles are provided using the ...

We describe an algorithm computing an optimal prefix free code for n unsorted positive weights in time within O ( n ( 1 + lg α ) ) ⊆ O ( n lg n ) , where the alternation α∈ [ 1 . . n − 1 ] approximates the minimal amount of sorti
Experiments on four datasets demonstrate the effectiveness of SPIRIT For reproducibility, source code is available at https://github.com/Rooooyy/SPIRIT (accessed on 11 January 2025). 2. Preliminary Hierarchical Text Classification. In a specific hierarchical text classification task, there exists L cla...
