ब्रायन Wilson केर्निघन, (जन्म: १९४२ in Toronto, Ontario, Canada) is a संगणकशास्त्रज्ञ who worked at बेल लॅब्ज alongside युनिक्स creators केन थॉम्प्सन and डेनिस रिची and contributed greatly to युनिक्स and its school of thought. He is also coauthor of the AWK and AMPL programming languages.
केर्निघन's name became widely known through co-authorship of the first book on the C programming language with Dennis Ritchie. Kernighan has said that he had no part in the design of the C language ('it's entirely Dennis Ritchie's work'). He authored many युनिक्स programs, including ditroff.
In collaboration with Shen Lin he devised well-known heuristics for two NP-complete optimization problems: graph partitioning and the travelling salesman problem. (In a display of authorial equity, the former is usually called the Kernighan-Lin algorithm, while the latter is styled Lin-Kernighan.)
केर्निघन was also software editor for Prentice-Hall International. His Software Tools series spread the essence of 'C/युनिक्स thinking' with makeovers for BASIC, FORTRAN, and Pascal - and most notably his 'Ratfor' (rational FORTRAN) was put in the public domain.
He has said that if stranded on an island with only one programming language it would have to be C.
The 'K' of K&R C and the 'K' in AWK stand for 'केर्निघन'.
He received his Bachelor's degree in Engineering Physics from the University of Toronto. He received his PhD in electrical engineering from Princeton University, where he has held a professorship in the department of computer science since 2000. Each fall he teaches a course called "Computers in Our World", which introduces the fundamentals of computing to non-majors.
He has on occasion revealed it was his own pun which led to the use of the name 'युनिक्स' (initially 'Unics') for the operating system Ken Thompson and Dennis Ritchie were working on.
Summary of Achievements
- Hello, world, a program originally written in B to demonstrate B's extrn variables (equivalent to C's extern)
- The AWK programming language, along with Al Aho and Peter J. Weinberger, and its book The AWK Programming Language
- The AMPL programming language
- Ratfor, along with P. J. Plauger
- Software Tools, a book and set of tools for Ratfor, cocreated in part with P. J. Plauger
- Software Tools in Pascal, a book and set of tools for PASCAL, with P. J. Plauger
- The Unix Programming Environment, a tutorial book along with Rob Pike
- The C Programming Language along with C creator Dennis Ritchie, the first ever book on C
- The pic typesetting language for troff
- The eqn typesetting language for troff, along with Lorinda Cherry
- The Practice of Programming, with Rob Pike
- Why Pascal is Not My Favorite Programming Language, a popular criticism of the Pascal programming language by Niklaus Wirth. Some parts of the criticism are obsolete due to ISO 7185 (Programming Languages - Pascal), the criticism was written before ISO 7185 was even created. See below for a link. (AT&T Computing Science Technical Report #100)
- ditroff, or "device independent troff", which allowed troff to be used with any device
- The m4 macro processing language, with Dennis Ritchie
