Frases de Robert W. Floyd

Robert W. Floyd fue un prominente científico estadounidense en informática.

Nacido en Nueva York, Floyd culminó el bachillerato a los 14 años. Se graduó en la Universidad de Chicago en 1953 a los 17 años y como Físico en 1958.

Operador de computadoras en los años 60, publicó sus primeros artículos los cuales fueron de gran influencia y fue nombrado profesor asociado en la Universidad de Carnegie Mellon. Seis años más tarde fue nombrado profesor en la Universidad de Stanford.

Entre sus contribuciones se encuentran el diseño y análisis de algoritmos eficientes para encontrar el camino más corto en un grafo y para el problema de reconocimiento de frases, pero probablemente su logro más importante fue el ser pionero, con su artículo de 1967 «Assigning Meanings to Programs», en el área de verificación de programas utilizando aserciones lógicas, donde aparece la importante noción de invariante, esencial para demostrar propiedades de programas iterativos.

Floyd recibió el Premio Turing de la ACM en 1978 «por tener una clara influencia en las metodologías para la creación de software eficiente y confiable, y por haber contribuido a la fundación de las subáreas teoría del reconocimiento de frases, semántica de los lenguajes de programación, verificación automatizada de programas, síntesis automatizada de programas y análisis de algoritmos».

Robert W. Floyd: Frases en inglés

“If the advancement of the general art of programming requires the continuing invention and elaboration of paradigms, advancement of the art of the individual programmer requires that he expand his repertory of paradigms.”

The Paradigms of Programming (1979)

“Although my own previous enthusiasm has been for syntactically rich languages like the Algol family, I now see clearly and concretely the force of Minsky's 1970 Turing lecture, in which he argued that Lisp's uniformity of structure and power of self reference gave the programmer capabilities whose content was well worth the sacrifice of visual form.”

The Paradigms of Programming (1979)

“If I ask another professor what he teaches in the introductory programming course, whether he answers proudly "Pascal" or diffidently "FORTRAN," I know that he is teaching a grammar, a set of semantic rules, and some finished algorithms, leaving the students to discover, on their own, some process of design.”

The Paradigms of Programming (1979)

“It is, therefore, possible to extend a partially specified interpretation to a complete interpretation, without loss of verifiability, […] This fact offers the possibility of automatic verification of programs, the programmer merely tagging entrances and one edge in each innermost loop.”

“A semantic definition of a particular set of command types, then, is a rule for constructing, for any command of one of these types, a verification condition on the antecedents and consequents.”

“To the designer of programming languages, I say: unless you can support the paradigms I use when I program, or at least support my extending your language into one that does support my programming methods, I don't need your shiny new languages. […] To persuade me of the merit of your language, you must show me how to construct programs in it.”

The Paradigms of Programming (1979)

“If there is ever a science of programming language design, it will probably consist largely of matching languages to the design methods they support.”

The Paradigms of Programming (1979)

“The establishment of formal standards for proofs about programs […] and the proposal that the semantics of a programming language may be defined independently of all processors for that language, by establishing standards of rigor for proofs about programs in the language, appears to be novel.”

“For having a clear influence on methodologies for the creation of efficient and reliable software, and for helping to found the following important subfields of computer science: the theory of parsing, the semantics of programming languages, automatic program verification, automatic program synthesis, and analysis of algorithms.”
