PRISM - Wikipedia
PRISM is a code name for a program under which the United States National Security Agency (NSA) collects internet communications from various U.S. internet companies.[1][2][3] The program is also known by the SIGAD US-984XN.[4][5] PRISM collects stored internet communications based on demands made to internet companies such as Google LLC and Apple under Section 702 of the FISA Amendments Act of 20
Delaunay triangulation - Wikipedia
A Delaunay triangulation in the plane with circumcircles shown In computational geometry, a Delaunay triangulation or Delone triangulation of a set of points in the plane subdivides their convex hull[1] into triangles whose circumcircles do not contain any of the points. This maximizes the size of the smallest angle in any of the triangles, and tends to avoid sliver triangles. The triangulation is
Huffman coding - Wikipedia
In computer science and information theory, a Huffman code is a particular type of optimal prefix code that is commonly used for lossless data compression. The process of finding or using such a code is Huffman coding, an algorithm developed by David A. Huffman while he was a Sc.D. student at MIT, and published in the 1952 paper "A Method for the Construction of Minimum-Redundancy Codes".[1] The o

Magic Roundabout (Swindon) - Wikipedia
The roundabout was constructed according to the design of Frank Blackmore,[3] of the British Transport and Road Research Laboratory. Traffic flow around the inner circle is anticlockwise, and traffic flows in the usual clockwise manner around the five mini-roundabouts on the outer loop. Swindon Magic Roundabout map with traffic direction and two routes from Fleming Way to Queen's Drive (give way a
Karatsuba algorithm - Wikipedia
Karatsuba multiplication of az+b and cz+d (boxed), and 1234 and 567 with z=100. Magenta arrows denote multiplication, amber denotes addition, silver denotes subtraction and cyan denotes left shift. (A), (B) and (C) show recursion with z=10 to obtain intermediate values. The Karatsuba algorithm is a fast multiplication algorithm. It was discovered by Anatoly Karatsuba in 1960 and published in 1962.
Shunting yard algorithm - Wikipedia
In computer science, the shunting yard algorithm is a method for parsing arithmetical or logical expressions, or a combination of both, specified in infix notation. It can produce either a postfix notation string, also known as Reverse Polish notation (RPN), or an abstract syntax tree (AST).[1] The algorithm was invented by Edsger Dijkstra, first published in November 1961[2], and named the "shunt
Zeckendorf's theorem - Wikipedia
The first 89 natural numbers in Zeckendorf form. Each rectangle has a Fibonacci number Fj as width (blue number in the center) and Fj−1 as height. The vertical bands have width 10. In mathematics, Zeckendorf's theorem, named after Belgian amateur mathematician Edouard Zeckendorf, is a theorem about the representation of integers as sums of Fibonacci numbers. Zeckendorf's theorem states that every
Timsort - Wikipedia
Timsort is a hybrid, stable sorting algorithm, derived from merge sort and insertion sort, designed to perform well on many kinds of real-world data. It was implemented by Tim Peters in 2002 for use in the Python programming language. The algorithm finds subsequences of the data that are already ordered (runs) and uses them to sort the remainder more efficiently. This is done by merging runs until
