DISTANCE GRAPH [9 records]

Record 1 2019-10-30

English

Subject field(s)
  • Computer Mathematics
  • Computer Programs and Programming
DEF

A graph traversal algorithm that explores nodes in the order of their distance from the roots, where distance is defined as the minimum path length from a root to the node.

OBS

It starts at the tree root (or some arbitrary node of a graph, sometimes referred to as a ’search key’), and explores all of the neighbor nodes at the present depth prior to moving on to the nodes at the next depth level.

French

Domaine(s)
  • Mathématiques informatiques
  • Programmes et programmation (Informatique)
CONT

L'algorithme de parcours en largeur permet de calculer les distances de tous les nœuds depuis un nœud source dans un graphe non pondéré (orienté ou non orienté). Il peut aussi servir à déterminer si un graphe non orienté est connexe.

Record 2 2016-06-03

English

Subject field(s)
  • Computer Mathematics
  • Artificial Intelligence
CONT

The A[ star]: algorithm is a best-first search method. It means that the algorithm simultaneously contains several paths which may all be candidates for the shortest path. At any time, it selects the most promising node(best-first) at a time for expansion, and incorporates the successor nodes into the search graph. The criterion for evaluation is the length of the path from start to the node plus the estimate of the remaining distance(cost). The theory says that if the remaining estimate is an underestimate, the first solution will be optimal.

OBS

A[star] search algorithm; A[star] algorithm: The word "star" and the square brackets that surround it replace the symbol representing a star, also known as an "asterisk," because it cannot be reproduced due to technical constraints.

French

Domaine(s)
  • Mathématiques informatiques
  • Intelligence artificielle
CONT

L'algorithme A[étoile] est un algorithme de recherche [du] meilleur chemin de type meilleur d'abord. L'idée est de parcourir le graphe G depuis le sommet source jusqu'au sommet cible en se déplaçant dans les «meilleurs» sommets, [c'est-à-dire] ceux ayant le plus petit coût global : coût du chemin depuis la source + coût estimé jusqu'à la cible.

OBS

algorithme de recherche A[étoile]; algorithme A[étoile] : Le mot «étoile» et les crochets qui l'entourent remplacent le symbole représentant une étoile, aussi appelé «astérisque», parce qu'il est impossible de le reproduire en raison de contraintes techniques.

Record 5 1994-06-01

English

Subject field(s)
  • Astronomy
DEF

A technique for measuring the distance modulus and hence the distance for a star cluster... the main sequence portion of a graph colour index versus apparent magnitude for the cluster is superimposed on the main sequence of a standard Hertzprung-Russell diagram, the spectral types of the two curves being made to overlap.

CONT

The distance to a given globular cluster may be found (1) by the main-sequence fitting technique, (2) by the apparent magnitudes of certain well known types of stars in the cluster, and (3) by the apparent angular diameter of the cluster.

French

Domaine(s)
