Qhov kom zoo dua ntawm Prim's algorithm yog nws qhov nyuaj, uas zoo dua li Kruskal's algorithm. Yog li ntawd, Prim's algorithm yuav pab tau thaum cuam tshuam nrog cov duab ntom ntom uas muaj ntau cov npoo. Txawm li cas los xij, Prim's algorithm tsis tso cai rau peb tswj ntau ntawm cov npoo xaiv thaum muaj ntau cov npoo nrog qhov hnyav tib yam tshwm sim.

Puas yog Prims zoo dua Kruskal?

Prim's Algorithm tau sai dua rau hauv qhov kev txwv thaum koj tau txais ib lub cim ntom heev nrog ntau cov npoo dua li vertices. Kruskal ua tau zoo dua hauv cov xwm txheej zoo (sparse graphs) vim nws siv cov ntaub ntawv yooj yim dua.

Vim li cas Prism algorithm ua haujlwm tau zoo?

(Nyob rau hauv qhov kev hwm no, Prim's algorithm zoo ib yam li Dijkstra's algorithm rau nrhiav txoj hauv kev luv tshaj.) … Prim's algorithm ua haujlwm tau zoo yog tias peb khaws cov npe d[v] ntawm qhov hnyav tshaj plaws uas txuas lub vertex, v, uas tsis nyob hauv tsob ntoo, mus rau ib qho vertex twb nyob hauv tsob ntoo..

Qhov algorithm twg zoo dua rau tsob ntoo tsawg kawg nkaus?

Nrhiav Yam Tsawg Kawg Nkaus Ntoo

Ib tug ob peb nrov algorithms rau nrhiav qhov tsawg kawg nkaus nrug muaj xws li: Kruskal's algorithm, Prim's algorithm thiab Boruvka's algorithm. Cov no ua haujlwm rau cov ntoo yooj yim spanning. Yog xav paub ntau ntxiv, tej zaum koj yuav tau siv software.

Qhov algorithm twg yog qhov zoo dua Prims lossis Kruskal tuaj yeem Prim's thiab Kruskal's algorithm yields txawv qhov tsawg kawg nkaus spanning ntoo?

Ntawd yog, Prim's algorithm yuav tawm los ib tsob ntoo tsawg kawg nkaus sib txawv dua li Kruskal's algorithm nyob rau hauv cov ntaub ntawv no, tab sis qhov ntawd yog vim hais tias ob qho tib si algorithm yuav ua rau muaj qhov sib txawv yam tsawg kawg nkaus spanning ntoo dua (ib qhov sib txawv. kev siv ntawm) nws tus kheej!
