Kruskal qhov tsawg kawg nkaus Spanning Ntoo Algorithm | Greedy Algo-2
- Cais tag nrho cov npoo hauv qhov tsis txo qis ntawm lawv qhov hnyav.
- Xaiv lub tsawg tshaj plaws ntug. Xyuas seb nws tsim ib lub voj voog nrog cov tsob ntoo tsim kom deb li deb. Yog tsis tsim lub voj voog, suav nrog ntug no. Tsis tas li ntawd, muab pov tseg.
- Rov ua kauj ruam # 2 kom txog thaum muaj (V-1) ntug hauv tsob ntoo .
Tib neeg kuj nug, dab tsi yog tus nqi qis tshaj ntawm tsob ntoo?
Cov nqi ntawm tsob ntoo yog qhov sib npaug ntawm qhov hnyav ntawm tag nrho cov npoo hauv qhov tsob ntoo . Yuav muaj ntau yam hla ntoo . Yam tsawg kawg nkaus tsob ntoo yog cov tsob ntoo qhov twg nqi yog yam tsawg kawg nkaus ntawm tag nrho cov hla ntoo . Kuj tseem muaj ntau tsawg kawg spanning ntoo.
Ib yam li ntawd, koj yuav pom qhov tsawg kawg nkaus spanning ntoo siv Kruskal's algorithm li cas? Kruskal lub algorithm rau nrhiav tus yam tsawg kawg nkaus nqi tsob ntoo siv txoj kev ntshaw ntshaw.
Kruskal's Spanning Tree Algorithm
- Kauj Ruam 1 - Tshem tag nrho cov voj voog thiab cov ntug sib luag.
- Kauj Ruam 2 - Npaj tag nrho cov npoo hauv lawv qhov kev txiav txim siab ntawm qhov hnyav.
- Kauj Ruam 3 - Ntxiv cov ntug uas muaj qhov hnyav tshaj plaws.
Ntxiv mus, qhov tsawg kawg nkaus spanning ntoo nrog piv txwv?
A tsawg kawg spanning ntoo yog ib hom tshwj xeeb ntawm tsob ntoo uas txo qhov ntev (lossis "qhov hnyav") ntawm cov npoo ntawm qhov tsob ntoo . Ib piv txwv yog ib lub tuam txhab cable xav nteg kab rau ntau lub zej zog; los ntawm kev txo qis ntawm cov cable tso, lub tuam txhab cable yuav txuag nyiaj. A tsob ntoo muaj ib txoj kev koom nrog ob lub vertices.
Koj txhais li cas los ntawm qhov tsawg kawg nkaus spanning ntoo?
A tsawg kawg spanning ntoo (MST) lub yam tsawg kawg nkaus hnyav tsob ntoo yog ib tug subset ntawm cov npoo ntawm ib qho kev cob cog rua, edge-weighted undirected graph uas txuas tag nrho cov vertices ua ke, tsis muaj ib tug cycles thiab nrog rau yam tsawg kawg nkaus ua tau tag nrho ntug hnyav. Nyob ntawd yog heev ob peb yam siv rau tsawg kawg spanning ntoo.

Dab tsi yog qhov ntsuas qhov tsawg kawg nkaus?
❑ “Txoj kev ntsuas qhov txwv (MDL) yog. txhais raws li qhov tsawg kawg nkaus concentration ntawm a. khoom uas ntsuas tau thiab. qhia nrog 99% kev ntseeg siab tias cov. analytes concentration yog ntau tshaj xoom
Yuav ua li cas koj yuav nrhiav tau nyob ze qhov kawg yog nws sab qaum teb ncej nyob?
Teb. Qhov chaw ntawm tus ncej ntawm li hlau nplaum tuaj yeem txiav txim siab los ntawm kev ncua nws dawb. Ib qho kev txwv tsis pub pub dawb bar hlau nplaum ib txwm taw qhia rau sab qaum teb thiab sab qab teb. Qhov kawg uas taw tes rau sab qaum teb yog tus ncej qaum teb ntawm cov hlau nplaum thaum kawg uas cov ntsiab lus mus rau sab qab teb yog tus ncej sab qab teb ntawm cov hlau nplaum
Qhov siab tshaj plaws thiab qhov tsawg kawg nkaus hauv lej yog dab tsi?
Hauv kev ua lej, qhov siab tshaj plaws thiab qhov tsawg kawg nkaus ntawm qhov muaj nuj nqi yog qhov loj tshaj plaws thiab qhov tsawg tshaj plaws uas qhov kev ua haujlwm yuav siv ntawm ib qho chaw. Yam tsawg kawg txhais tau tias qhov tsawg tshaj plaws koj tuaj yeem ua tau ib yam dab tsi
Vim li cas tam sim no yog qhov tsawg kawg nkaus nyob rau hauv parallel resonance?
Resonance tshwm sim nyob rau hauv parallel RLC Circuit Court thaum tag nrho cov hluav taws xob tam sim no yog "hauv-theem" nrog cov khoom siv hluav taws xob vim tias ob qho khoom siv hluav taws xob tshem tawm ib leeg. Tsis tas li ntawm resonance qhov tam sim no rub los ntawm cov khoom siv kuj yog qhov tsawg kawg nkaus thiab txiav txim siab los ntawm tus nqi ntawm qhov sib npaug
Qhov siab tshaj plaws lossis qhov tsawg kawg nkaus ntawm parabola yog dab tsi?
Vertical parabolas muab cov ntaub ntawv tseem ceeb: Thaum lub parabola qhib, lub vertex yog qhov qis tshaj plaws ntawm daim duab - hu ua qhov tsawg kawg nkaus, lossis min. Thaum lub parabola qhib, lub vertex yog qhov siab tshaj plaws ntawm daim duab - hu ua themaximum, lossis max
