Tshaj tawm rau lub Plaub Hlis 4, 2017. Dav - Nrhiav thawj zaug yog zoo li traversing ib tsob ntoo qhov twg txhua node yog ib lub xeev uas tej zaum yuav ib tug muaj peev xwm sib tw rau kev daws. Nws nthuav cov nodes los ntawm cov cag ntoo thiab tom qab ntawd tsim ib theem ntawm tsob ntoo ntawm ib lub sij hawm kom txog rau thaum pom muaj kev daws teeb meem.
Ib yam li ntawd, dab tsi yog qhov tob ua ntej nrhiav hauv kev txawj ntse?
Qhov tob - thawj nrhiav ( DFS ) yog ib qho algorithm rau traversing los yog nrhiav tsob ntoo lossis daim duab cov ntaub ntawv. Lub algorithm pib ntawm lub hauv paus node (xaiv ib co arbitrary node raws li lub hauv paus node nyob rau hauv cov ntaub ntawv ntawm ib daim duab) thiab tshawb nrhiav kom deb li deb tau raws li txhua ceg ua ntej backtracking.
Tsis tas li ntawd, dab tsi yog qhov zoo tshaj plaws kev tshawb nrhiav hauv kev txawj ntse? Zoo tshaj - thawj nrhiav yog a nrhiav algorithm uas tshawb txog ib daim duab los ntawm kev nthuav dav cov kev cog lus feem ntau xaiv raws li txoj cai. Hom tshwj xeeb ntawm no nrhiav hu ua greedy zoo tshaj plaws - thawj nrhiav los yog ntshiab tshawb nrhiav heuristic.
Tsis tas li ntawd, qhov dav thawj qhov kev tshawb nrhiav nrog piv txwv yog dab tsi?
Breadth Thawj Nrhiav ( BFS ) algorithm traverses ib daim duab nyob rau hauv ib tug dav dav motion thiab siv ib tug queue kom nco ntsoov kom tau lub vertex tom ntej no mus pib ib tug nrhiav , thaum kawg tuag tshwm sim nyob rau hauv tej iteration. Raws li nyob rau hauv piv txwv muab saum toj no, BFS algorithm traverses ntawm A mus rau B rau E rau F ua ntej ces mus rau C thiab G kawg mus rau D.
Kev tshawb nrhiav dav dav siv rau dab tsi?
Dav - thawj nrhiav (BFS) yog ib daim duab tseem ceeb nrhiav algorithm uas yog siv rau daws ntau yam teeb meem nrog rau kev nrhiav txoj hauv kev luv tshaj plaws hauv daim duab thiab daws cov kev ua si sib tw (xws li Rubik's Cubes).

Kev tshawb fawb txog kev ruaj ntseg thiab kev txawj ntse yog dab tsi?
Lub Bachelor of Science degree hauv Kev Ruaj Ntseg Hauv Ntiaj Teb thiab Kev Txawj Ntse (GSIS) yog tsim los tsim cov kws tshaj lij kev nyab xeeb thiab kev txawj ntse yav tom ntej nrog kev nkag siab dav ntawm kev sib raug zoo thoob ntiaj teb hauv kev nom kev tswv, kev cai lij choj, tsoomfwv, kev lag luam, kev hloov pauv, kev tshawb fawb thiab thev naus laus zis, kev tsim tub rog
Dab tsi yog qhov dav thawj qhov kev tshawb nrhiav thiab qhov tob thawj qhov kev tshawb fawb?
BFS sawv rau Breadth First Search. DFS sawv cev rau Kev Tshawb Nrhiav Qhov tob. 2. BFS (Breadth First Search) siv Queue cov qauv ntaub ntawv los nrhiav txoj hauv kev luv tshaj. BFS tuaj yeem siv los nrhiav ib qhov chaw luv tshaj plaws hauv cov duab tsis hnyav, vim tias hauv BFS, peb mus txog qhov kawg uas muaj qhov tsawg kawg nkaus ntawm cov npoo los ntawm qhov chaw vertex
Dab tsi yog kev txawj ntse txawj ntse hauv programming?
Artificial Intelligence (AI) yog kev kawm txog computer science tsom mus rau kev tsim software lossis tshuab uas qhia txog tib neeg kev txawj ntse
Dab tsi yog qhov zoo ntawm kev tshawb fawb zoo tshaj li kev tshawb fawb ntau?
Cov ntaub ntawv los ntawm kev tshawb fawb ntau - xws li kev lag luam loj, pej xeem, thiab cov neeg siv nyiam - muab cov ntaub ntawv tseem ceeb rau kev txiav txim siab ua lag luam. Kev tshawb fawb zoo muab cov ntaub ntawv tseem ceeb rau kev siv hauv kev tsim cov khoom lag luam-nrog rau cov ntaub ntawv hais txog cov neeg siv khoom xav tau, tus qauv coj tus cwj pwm, thiab cov ntaub ntawv siv
Dab tsi yog qhov kev txawj ntse ntawm kev txawj ntse?
Kev paub txog kev txawj ntse yog lub peev xwm los daws kev xav, daws teeb meem, siv cov tswv yim xav tsis thoob, nkag siab cov tswv yim nyuaj, kawm sai thiab kawm los ntawm kev paub
