Tree vs Graph in Data Structure
Vim ntoo thiab daim duab yog cov ntaub ntawv tsis-linear uas siv los daws cov teeb meem nyuaj hauv computer, paub qhov txawv ntawm tsob ntoo thiab daim duab hauv cov ntaub ntawv qauv yog qhov tseem ceeb. Ob lub qauv ntaub ntawv sawv cev rau cov ntaub ntawv hauv daim ntawv lej. Lub hom phiaj tseem ceeb ntawm tsab xov xwm yog los qhia txog qhov tseem ceeb ntawm cov ntaub ntawv uas tsis yog-linear. Nws kuj suav nrog qhov sib txawv tseem ceeb ntawm ob cov ntaub ntawv no.
tsob ntoo hauv cov ntaub ntawv yog dab tsi?
Tsob ntoo yog cov ntaub ntawv tsis-linear uas txhua yam ntaub ntawv tau teeb tsa hauv qee qhov sib lawv liag. Tsob ntoo txhais cov txheej txheem ntawm cov ntaub ntawv finite. Txhua yam ntaub ntawv yog hu ua node. Muaj ib qho tshwj xeeb niam txiv node uas tseem hu ua lub hauv paus ntawm. Tag nrho lwm cov nodes yog me nyuam node los yog sub me nyuam nodes. Lub hom phiaj tseem ceeb ntawm tsob ntoo yog sawv cev hierarchical kev sib raug zoo ntawm cov ntaub ntawv sib txawv. Ib txwm ntoo loj hlob nyob rau sab saud, tab sis cov ntaub ntawv qauv ntoo hlob nyob rau hauv nqe lus. Tag nrho cov sub-nodes txuas nrog tsob ntoo tau muab faib ua ntau theem. Binary ntoo yog qhov piv txwv feem ntau ntawm cov ntaub ntawv tsis-linear. Qhov siab tshaj plaws ntawm ib tsob ntoo binary yog ob. Nws txhais tau tias qhov siab tshaj plaws ob qhov tuaj yeem txuas nrog txhua tus niam txiv node.
Dab tsi yog Graph hauv Cov Qauv Qauv?
Graph yog cov ntaub ntawv uas tsis yog-linear nrov uas siv los daws ntau yam teeb meem hauv computer. Lawv yog siv los tsim ntau yam kev ua si thiab puzzles. Cov duab tuaj yeem muab faib ua ntau pawg. Cov no yog:
• Directed Graph: Nyob rau hauv daim duab qhia, txhua ntug yog txhais los ntawm kev txiav txim ob vertices.
• Cov duab tsis qhia: Hauv daim duab tsis qhia, txhua ntug yog txhais los ntawm qhov tsis tau txiav txim ntawm cov kab ntsug
• Txuas daim duab: Hauv txoj kev sib txuas, muaj txoj hauv kev los ntawm txhua qhov vertex mus rau lwm qhov vertex.
• Non Connected Graph: Hauv daim duab tsis txuas, txoj kev tsis muaj nyob ntawm ib qho vertex mus rau lwm qhov vertex.
• Weighted Graph: Nyob rau hauv cov duab hnyav, qee qhov hnyav yog txuas rau ntawm ntug.
• Simple Graph lossis Multi Graph
Similarities ntawm tsob ntoo thiab duab hauv cov ntaub ntawv qauv
• Cov ntoo thiab daim duab ob yog cov ntaub ntawv tsis yog kab uas siv los daws cov teeb meem nyuaj hauv computer.
• Ob lub qauv ntaub ntawv siv cov niam txiv ntawm thiab ntau lub npe.
Qhov txawv ntawm Tsob Ntoo thiab Daim Duab Hauv Cov Ntaub Ntawv yog dab tsi?
• Tsob ntoo raug suav hais tias yog qhov tshwj xeeb ntawm daim duab. Nws tseem hu ua daim duab sib txuas tsawg kawg nkaus.
• Txhua tsob ntoo tuaj yeem suav tias yog daim duab, tab sis txhua daim duab tsis tuaj yeem suav tias yog tsob ntoo.
• Tus kheej-loops thiab circuits tsis muaj nyob rau hauv tsob ntoo raws li nyob rau hauv cov teeb meem.
• Rau kev tsim tsob ntoo, koj xav tau ib tus niam txiv node thiab ntau lub npe. Txhawm rau tsim ib daim duab, koj xav tau vertices thiab ntug. Ntug yog ib khub ntawm vertices.
Qhov kev sib tham saum toj no xaus lus tias tsob ntoo thiab daim duab yog cov ntaub ntawv nrov tshaj plaws uas siv los daws ntau yam teeb meem nyuaj. Graphs yog cov ntaub ntawv nrov tshaj plaws uas yog siv hauv kev tsim computer, cov qauv ntawm lub cev thiab engineering science. Feem ntau ntawm cov puzzles yog tsim los ntawm kev pab ntawm cov ntaub ntawv graph. Qhov teeb meem nyob deb tshaj plaws yog cov ntaub ntawv siv ntau tshaj plaws. Hauv qhov teeb meem no, peb yuav tsum xam qhov kev ncua deb ntawm ob lub vertices.
