A tsob ntoo yog cov ntaub ntawv nonlinear qauv , piv rau arrays, txuas cov npe, pawg thiab cov kab uas yog cov ntaub ntawv linear cov qauv . A tsob ntoo tuaj yeem npliag tsis muaj cov nodes lossis a tsob ntoo yog a qauv muaj xws li ib tug node hu ua lub hauv paus thiab xoom los yog ib tug los yog ntau tshaj subtrees.

Tsis tas li ntawd, cov qauv ntoo yog dab tsi?

A ntoo qauv yog ib qho algorithm rau tso thiab nrhiav cov ntaub ntawv (hu ua cov ntaub ntawv lossis cov yuam sij) hauv cov ntaub ntawv. Lub algorithm pom cov ntaub ntawv los ntawm kev rov xaiv dua ntawm cov ntsiab lus txiav txim hu ua nodes. Ib lub pob tuaj yeem muaj tsawg li ob ceg (tseem hu ua menyuam yaus), lossis ntau npaum li ntau lub kaum os.

Tom qab ntawd, lo lus nug yog, tsob ntoo yog dab tsi thiab nws hom hauv cov ntaub ntawv qauv? Tsob ntoo yog non-linear cov ntaub ntawv qauv . A tsob ntoo tuaj yeem sawv cev siv ntau yam keeb kwm yav dhau los lossis cov neeg siv txhais hom ntaub ntawv . Txhawm rau siv tsob ntoo , peb tuaj yeem siv arrays, txuas cov npe, cov chav kawm lossis lwm yam hom ntawm cov ntaub ntawv qauv . Nws yog ib pawg ntawm cov nodes uas muaj feem xyuam nrog ib leeg.

Ib yam li ntawd, daim duab tsob ntoo yog dab tsi?

A Ntoo Diagram yog ib txoj kev ntawm visually sawv cev hierarchy nyob rau hauv a tsob ntoo -zoo li qauv . Feem ntau cov qauv ntawm a Ntoo Diagram muaj cov ntsiab lus xws li lub hauv paus node, ib tug tswv cuab uas tsis muaj superior/niam txiv. Thaum kawg, cov nplooj nodes (los yog qhov kawg-nodes) yog cov tswv cuab uas tsis muaj menyuam lossis cov menyuam.

tsob ntoo thiab nws cov khoom yog dab tsi?

Ntoo thiab nws cov khoom Lus Txhais - A Tsob ntoo yog ib qho txuas acyclic undirected graph. Muaj ib txoj hauv kev tshwj xeeb ntawm txhua khub ntawm vertices hauv G. A tsob ntoo nrog N tus naj npawb ntawm vertices muaj (N−1) tus lej ntawm ntug.
