POLYNOMIAL ALGORITHM [3 records]

Record 1 2026-01-08

English

Subject field(s)
  • Computer Mathematics
  • Computer Programs and Programming
  • Artificial Intelligence
CONT

Polynomial-time algorithms are considered to be efficient, while exponential-time algorithms are considered inefficient, because the execution times of the latter grow much more rapidly as the problem size increases.

Domaine(s)
  • Mathématiques informatiques

Record 2 2016-12-30

English

Subject field(s)
  • Mathematics
  • Artificial Intelligence
DEF

An algorithm which produces a feasible solution [but not necessarily an optimal solution].

CONT

An approximate algorithm is a way of dealing with NP-completeness for optimization problems, [although this] technique does not guarantee the best solution. The goal of an approximation algorithm is to come as close as possible to the optimum value in a reasonable amount of time which is at most polynomial time.

French

Domaine(s)
  • Mathématiques
  • Intelligence artificielle
DEF

Algorithme qui conduit toujours à une solution réalisable mais pas nécessairement à une solution optimale.

CONT

Les problèmes d'optimisation NP-difficiles ne sont pas tous équivalents en termes "d'approximabilité" : certains [...] peuvent être approximés avec un facteur quelconque, la complexité en temps de l'algorithme d'approximation augmentant lorsque le facteur d'erreur diminue [...]

CONT

En informatique théorique, un algorithme d'approximation est une méthode permettant de calculer une solution approchée à un problème algorithmique d'optimisation. Plus précisément, c'est une heuristique garantissant à la qualité de la solution qui fournit un rapport inférieur (si l'on minimise) à une constante, par rapport à la qualité optimale d'une solution, pour toutes les instances possibles du problème.

Spanish

Campo(s) temático(s)
  • Matemáticas
  • Inteligencia artificial
DEF

Algoritmo que entrega una solución con una garantía teórica de cercanía al óptimo.

packet level error detection algorithm which exploits the attributes of modulo-2 arithmetic to generate, through the use of a generator polynomial, a transmission polynomial comprising the message polynomial and a parity polynomial
