#1340
Rucsac
Într-un magazin sunt n
obiecte; pentru fiecare se cunoaște greutatea G
și valoarea V
. Un hoț intră în magazin având un rucsac ce poate transporta o greutate maximă GMax
. El va fura anumite obiecte, sau porțiuni de obiecte, astfel încât suma greutăților obiectelor furate să nu depășească GMax
.
Să se stabilească câștigul maxim pe care îl poate obține hoțul. Câștigul este egal cu suma valorilor obiectelor furate. Câștigul adus de o fracțiune de obiect este direct proporțional cu greutatea fracțiunii.
