ALGOL is a family of imperative computer programming languages originally developed in 1958. ALGOL heavily influenced many other languages and was the standard method for algorithm description used by the Association for Computing Machinery (ACM) in textbooks and academic sources for more than thirty years.
The Burroughs Large Systems Group produced a family of large 48-bit mainframes using stack machine instruction sets with dense syllables. The first machine in the family was the B5000 in 1961. It was optimized for compiling ALGOL 60 programs extremely well, using single-pass compilers. It evolved into the B5500. Subsequent major redesigns include the B6500/B6700 line and its successors, as well as the separate B8500 line.
ALGOL 60 is a member of the ALGOL family of computer programming languages. It followed on from ALGOL 58 which had introduced code blocks and the begin and end pairs for delimiting them, representing a key advance in the rise of structured programming. ALGOL 60 was the first language implementing nested function definitions with lexical scope. It gave rise to many other programming languages, including CPL, Simula, BCPL, B, Pascal, and C. Practically every computer of the era had a systems programming language based on ALGOL 60 concepts.
ALGOL 68 is an imperative programming language that was conceived as a successor to the ALGOL 60 programming language, designed with the goal of a much wider scope of application and more rigorously defined syntax and semantics.
Elliott ALGOL is a compiler for the programming language ALGOL 60, for the Elliott 803 computer made by Elliott Brothers in the United Kingdom. It was implemented by Tony Hoare and others. It differed slightly from the reference version of ALGOL, particularly in the supported character set. First released in February 1962, it is believed to be the first implementation of an ALGOL 60 compiler in a commercial context and was an unexpectedly popular product for the company.

USS Algol (AKA-54) was an Andromeda-class attack cargo ship. She was the first ship of the United States Navy by this name, after Algol, a fixed star in the constellation Perseus. Algol served as a commissioned ship for 22 years and 1 month.
The Algol-class vehicle cargo ships, also known as Fast Sealift Ships (FSS) or SL-7s, are currently the fastest cargo ships in the world, capable of speeds in excess of 33 knots (61 km/h). Originally built in 1972 and 1973 as high-speed container ships known as SL-7's for Sea-Land Services, Inc., the ships' high operating costs limited their profitability. All eight ships were acquired by the US Navy in 1981 and 1982, with the last ship converted, delivered to and placed in service with Military Sealift Command in 1986. The conversion entailed the installation of four cranes, addition of roll on/roll off capability and a redesign of the cargo hold to better facilitate storage of vehicles. Due largely to their high cost of operation, all fast sealift ships are kept in Reduced Operating Status, but can be activated and ready to sail in 96 hours. All ships are named after bright stars in the night sky.
ALGOL 68-R was the first implementation of the Algorithmic Language ALGOL 68.
SS Algol is an Algol-class vehicle cargo ship that is currently maintained by the United States Maritime Administration as part of the Military Sealift Command's Ready Reserve Force. She was built as a high speed container ship by Rotterdamsche Droogdok Maatschappij N.V. in Rotterdam, the Netherlands, hull no. 331, for Sea-Land Service, Inc. and named SS Sea-Land Exchange, USCG ON 546383, IMO 7303205. Due to her high operating cost, Sea-Land Exchange was sold to the United States Navy in October 1981 as USNS Algol (T-AK-287).
USNS Pollux (T-AK-290), later T-AKR-290, the fourth United States Navy ship of the name, is an Algol-class vehicle cargo ship that is currently maintained by the United States Maritime Administration as part of the Ready Reserve Force (RRF) as SS Pollux (T-AKR-290).
SS Altair is an Algol class vehicle cargo ship that is currently maintained by the United States Maritime Administration as part of the Military Sealift Command's Ready Reserve Force (RRF). She was built as a high speed container ship by Rheinstahl Nordseewerke in Emden, West Germany, hull no. 431, for Sea-Land Service, Inc. and named SS Sea-Land Finance, USCG ON 550722, IMO 7315571. Due to her high operating cost, she was sold to the United States Navy on 5 January 1982 as USNS Altair (T-AK-291).
SS Regulus is an Algol class vehicle cargo ship that is currently maintained by the United States Maritime Administration as part of the Military Sealift Command's Ready Reserve Force (RRF). She was built as a high speed container ship by A.G. Weser in Bremen, West Germany, hull no. 1383, for Sea-Land Service, Inc. and named SS Sea-Land Commerce, USCG 545200, IMO 7302897. Due to her high operating cost, she was sold to the United States Navy on 27 October 1981 as USNS Regulus (T-AK-292).
