  2. Cuprins • Definitii • Exemple • Implementari • matrice de adiacenta • structuri de adiacenta

  3. Definitii (1) • Graful este o colectie de arce si noduri. • Gradul unui nod este numarul de adiacente al acelui nod. • Gradul grafului este gradul maxim al nodurilor acelui graf.

  4. Definitii (2) • Drum de la nodul x la nodul y e o succesiune de noduri conectate prin arce : x, n1, n2, n3,..., y • Lungimea drumului fiind data de numarul de arce. • Ciclu e un drum cu acelasi nod initial si final.

  5. Defintii (3) • Graf conex daca toate perechile sale de noduri sunt conectate. • Graf complet de ordinul n contine arcuri î ntre toate perechile ce se pot forma cu cele n noduri (n*(n-1)/2 arce ). • Graf rar daca are relativ putine arce. • Graf dens daca e aproape complet. • Graf orientat daca arcele au sens precizat. • Graf ponderat daca arcelor sale li se asociaza câte o valoare.
