Algol \Al"gol\, n. [Ar. al-gh[=u]l destruction, calamity, fr. gh[=a]la to take suddenly, destroy.] (Astron.) A fixed star, in Medusa's head, in the constellation Perseus, remarkable for its periodic variation in brightness.
Douglas Harper's Etymology Dictionary
Beta Persei, variable star in the constellation Perseus, late 14c., literally "the Demon," from Arabic al-ghul "the demon" (see ghoul). It corresponds, in modern representations of the constellation, to the gorgon's head Perseus is holding, but it probably was so called because it visibly varies in brightness every three days, which sets it apart from other bright stars. The computer language (1959) is a contraction of algo(rithmic) l(anguage); see algorithm.
Wiktionary
n. (context computing English) A high-level programming language mostly used for solving mathematical and scientific problems.
Wikipedia
ALGOL (short for Algorithmic Language) is a family of imperative computer programming languages, originally developed in the mid-1950s, which greatly influenced many other languages and was the standard method for algorithm description used by the ACM in textbooks and academic sources for more than thirty years.
In the sense that most modern languages are "Algol-like", it was arguably the most successful of the four high-level programming languages with which it was roughly contemporary: Fortran, Lisp, and COBOL. It was designed to avoid some of the perceived problems with FORTRAN and eventually gave rise to many other programming languages, including BCPL, B, Pascal, PL/I, Simula, and C. ALGOL introduced code blocks and the begin…end pairs for delimiting them. It was also the first language implementing nested function definitions with lexical scope. Moreover, it was the first programming language which gave detailed attention to formal language definition and through the Algol 60 Report introduced Backus–Naur Form, a principal formal grammar notation for language design.
There were three major specifications:
- ALGOL 58 – originally proposed to be called IAL (for International Algebraic Language).
- ALGOL 60 – first implemented as X1 ALGOL 60 in mid-1960 – revised 1963
- ALGOL 68 – revised 1973 – introduced new elements including flexible arrays, slices, parallelism, operator identification, and various extensibility features.
Niklaus Wirth based his own ALGOL W on ALGOL 60 before developing Pascal. Algol-W (for the IBM 360) was based on the proposal for the next generation ALGOL, but the ALGOL 68 committee decided on a design that was more complex and advanced, rather than a cleaned, simplified ALGOL 60. The official ALGOL versions are named after the year they were first published.
Algol 68 is substantially different from Algol 60 and was not well received, so that in general "Algol" means Algol 60 and dialects thereof. Fragments of ALGOL-like syntax are sometimes still used as pseudocode.
Algol or ALGOL may mean:
Algol: Tragedy of Power is a 1920 German science fiction film about an alien from the planet Algol.
Algol: The Magazine About Science Fiction was published from 1963-1984 by Andrew Porter. The name was changed to Starship in 1979.
It won a Hugo Award for Best Fanzine in 1974, in a tie with Richard E. Geis' Science Fiction Review; and received five other nominations for the Hugo (1973, 1975, 1976, and 1981). Initially a two-page fanzine printed by spirit duplicator, it expanded rapidly, moving to offset covers, then adding mimeographed contents, ultimately becoming a printed publication with the 16th issue. It went to a full color cover with the 24th issue; ultimately the circulation rose to 7,000. Columnists at various times included Ted White, Richard A. Lupoff, Susan Wood, Vincent Di Fate, Robert Silverberg, Frederik Pohl, Joe Sanders and Bhob Stewart.
Algol was an avant-garde Catalan magazine edited by the artistic group Dau al Set and first published in 1947. It was founded by Joan Pons and Joan Brossa and edited by Enric Tomo i Freixes. Only 100 copies of Algol were published. The 12-page magazine was printed on guarro, a type of linen paper.
Dau al Set was formed by the poet Joan Brossa, the philosopher Arnau Puig and the painters Joan Pons, Antoni Tàpies, Modest Cuixart and Joan-Josep Tharrats. It was a very important group in the Spanish post-war era. The magazine included literary texts by Brossa and Puig and illustrations by Pons, Jordi Mercadé and Francesc Boadella.
The group later published another magazine, called Dau al Set after their own name, which was the sequel to Algol. Dau al Set was first published in 1948 and had a total of 56 pages. It also contained works by Brossa, Puig, and many other artists.
The Algol family of solid-fuel rocket stages and boosters built by Aerojet (now Aerojet Rocketdyne) and used on a variety of launch vehicles. It was developed by Aerojet from the earlier Jupiter Senior and the Navy Polaris programs. Upgrades to the Algol motor occurred from 1960 till the retirement of the Scout launch vehicle in 1994.
Solid propellant rocket stage. Loaded/empty mass 10,705/1,900 kg. Thrust 470.93 kN. Vacuum specific impulse 236 seconds. Variations included Algol I, I-D, II, II-A, II-B and possibly others. Another popular rating was 40KS-115,000 (52,000 kgf for 40 seconds), also known as Senior.
They were initially developed as the first-stage motor of the Scout rocket. The design was based the Polaris, a sea-to-air missile developed for the United States Navy at the Jet Propulsion Laboratory.
