Abstract: This research work introduces a clustering-based in-place sorting algorithm, cluster sort. It is designed in such a way that it improves sorting efficiency by using data locality. It works ...

Discover how the Luhn Algorithm verifies credit card accuracy, supports secure transactions, and helps prevent errors in inputting Social Security numbers.

Abstract: The identification of key nodes is vital in the research of many complex networks such as protein networks. Currently, the main research focuses on ordinary graphs that cannot describe ...

There is a new sorting algorithm a deterministic O(m log2/3 n)-time algorithm for single-source shortest paths (SSSP) on directed graphs with real non-negative edge weights in the comparison-addition ...

If you want to solve a tricky problem, it often helps to get organized. You might, for example, break the problem into pieces and tackle the easiest pieces first. But this kind of sorting has a cost.

The Floyd-Warshall algorithm is a fundamental solution in graph theory for finding the shortest paths between all pairs of vertices in a weighted graph. This project explores the theoretical ...

Gretchen Watkins, president of Shell USA, Houston, is leaving on July 31, after seven years with the energy giant. Shell’s EVP Gulf of America Colette Hirstius will succeed Watkins effective Aug. 1.

The energy giant Shell plans to pull back from the chemical industry and instead focus on its liquified natural gas business. Speaking at the firm’s capital markets day meeting on March 25, Shell CEO ...

Analysis shows the oil giant sharply increased its use of carbon credits to offset its emissions as the voluntary market faced criticism. As the world’s voluntary carbon market has faced doubts about ...
