Google is holding seven public meetings across Europe to debate issues raised by the "right to be forgotten" ruling. The ruling by the European Court of Justice lets people ask Google to remove some types of information about them from its search index...
How much does the earth weigh? According to Terry Quinn, emeritus director of the International Bureau of Weights and Measures, the Earth weighs about 7,000,000,000,000,000,000,000,000 Kg.
Intel has launched a generation of processors with the smallest transistors ever featured in a commercial product. The Core M chip is the first in the family of Intel's next-generation Broadwell processors...
Thousands of Britons could be inadvertently sharing their digital secrets with anyone who knows where to click, suggests a BBC investigation. At risk are photographs, home videos and music collections as well as scans of documents such as passports, tax forms and other sources of personal data.
As drugs - both legal and illegal - pass through us, they enter the UK's waterways. But can this really lead to a change in the feeding habits, and even the sex, of wildlife? Most people go to a music festival for the music, the mud and the social scene...
William Meredith, from Hillview, Kentucky, was subsequently arrested by police. According to local media, he was arrested and charged with first degree criminal mischief and first degree wanton endangerment.
In the US, poverty, deprivation and exploitation draws thousands of its own children down into a dark underworld that offers few ways out. It is a world few Americans are aware of. But tens of thousands of American children are thought to be sexually exploited every year.
Police are searching for a man who failed to rob a sandwich shop in Rhode Island after being ignored by the teenage employees. The suspect entered a Subway store on Monday, and demanded money from the two employees who "did not respond", according to police...
Russian President Vladimir Putin "personally ordered" the killing of Alexander Litvinenko, the inquiry into the former spy's death has heard. Ben Emmerson QC, for Mr Litvinenko's family, said in his closing statement that Russian state responsibility had been proven "beyond reasonable doubt"...
The object, believed to be part of a wing, left Reunion in the Indian Ocean on a flight to Paris on Friday evening. From there it will be transported to a defence ministry laboratory in Toulouse for analysis.
Without a clever algorithm, graph cycle detection takes a lifetime. Tarjan's approach in PHP: …...
In the mathematical theory of directed graphs, a graph is said to be strongly connected if every vertex is reachable from every other vertex. The strongly connected components of an arbitrary directed graph form a partition into subgraphs that are themselves strongly connected.

In computer science, Kosaraju's algorithm (also known as the Kosaraju–Sharir algorithm) is a linear time algorithm to find the strongly connected components of a directed graph. Aho, Hopcroft and Ullman credit it to an unpublished paper from 1978 by S. Rao Kosaraju.
 cycle graph theory algorithm
In graph theory, the strongly connected components of a directed graph may be found using an algorithm that uses depth-first search in combination with two stacks, one to keep track of the vertices in the current component and the second to keep track of the current search path.
 cycle graph theory algorithm
In mathematics, and more specifically in graph theory, a directed graph (or digraph) is a graph, or set of nodes connected by edges, where the edges have a direction associated with them. In formal terms, a digraph is a pair (sometimes ) of:[1]
 cycle graph theory
In graph theory, there are several different types of object called cycles; a closed walk and a simple cycle. A closed walk consists of a sequence of vertices starting and ending at the same vertex, with each two consecutive vertices in the sequence adjacent to each other in the graph.
 cycle graph theory
In graph theory, a loop (also called a self-loop or a "buckle") is an edge that connects a vertex to itself. A simple graph contains no loops. For an undirected graph, the degree of a vertex is equal to the number of adjacent vertices.

In computer science, the time complexity of an algorithm quantifies the amount of time taken by an algorithm to run as a function of the length of the string representing the input[1]:226.
