1995 – AdaBoost algorithm, the first practical boosting algorithm, was introduced by Yoav Freund and Robert Schapire; 1995 – soft-margin support vector machine algorithm was published by Vladimir Vapnik and Corinna Cortes. It adds a soft-margin idea to the 1992 algorithm by Boser, Nguyon, Vapnik, and is the algorithm that people usually ...
Knuth embodied the idea of literate programming in the WEB system. The same WEB source is used to weave a TeX file, and to tangle a Pascal source file. These in their turn produce a readable description of the program and an executable binary respectively. A later iteration of the system, CWEB, replaces Pascal with C, C++, and Java. [46]
Had a clear influence on methodologies for the creation of efficient and reliable software; helped to found these important sub-fields of computer science: theory of parsing, semantics of programming languages, automatic program verification, automatic program synthesis, and analysis of algorithms [28]
Algorithm analysis resembles other mathematical disciplines as it focuses on the algorithm's properties, not implementation. Pseudocode is typical for analysis as it is a simple and general representation. Most algorithms are implemented on particular hardware/software platforms and their algorithmic efficiency is tested using real code. The ...
Speaking at a software conference in 2009, Tony Hoare hyperbolically apologized for inventing the null reference: [25] [26] I call it my billion-dollar mistake. It was the invention of the null reference in 1965. At that time, I was designing the first comprehensive type system for references in an object oriented language . My goal was to ...
Edsger Wybe Dijkstra (/ ˈ d aɪ k s t r ə / DYKE-strə; Dutch: [ˈɛtsxər ˈʋibə ˈdɛikstraː] ⓘ; 11 May 1930 – 6 August 2002) was a Dutch computer scientist, programmer, software engineer, mathematician, and science essayist.
Before the microcomputer, a successful software program typically sold up to 1,000 units at $50,000–60,000 each. By the mid-1980s, personal computer software sold thousands of copies for $50–700 each. Companies like Microsoft, MicroPro, and Lotus Development had tens of millions of dollars in annual sales. [37]
Simon said that they had "solved the venerable mind–body problem, explaining how a system composed of matter can have the properties of mind". [63] 1958 John McCarthy (Massachusetts Institute of Technology or MIT) invented the Lisp programming language. [58] Herbert Gelernter and Nathan Rochester (IBM) described a theorem prover in geometry. [58]
