Cov lub sij hawm complexity ntawm Prim'sAlgorithm yog O ((V + E) l o g V) vim hais tias txhua qhov vertex yog inserted nyob rau hauv qhov tseem ceeb queue tsuas yog ib zaug thiab insertion nyob rau hauv priorityqueue coj logarithmic sij hawm.
Tsis tas li ntawd, lub sijhawm nyuaj ntawm Kruskal algorithm yog dab tsi?
nyuaj . Kruskal lub algorithm tuaj yeem ua rau khiav hauv O (E log E) sij hawm , los yog sib npaug, O (E log V) sij hawm , qhov twg E yog tus naj npawb ntawm cov npoo hauv daim duab thiab V yog tus naj npawb ntawm cov vertices, tag nrho nrog cov ntaub ntawv yooj yim.
Ib yam li ntawd, qhov twg zoo dua Prims lossis Kruskal? Kruskal cov Algorithm: ua zoo dua intypical xwm txheej (sparse graphs) vim nws siv cov ntaub ntawv yooj yim dua. Prim cov Algorithm: yog qhov nrawm nrawm dua nyob rau hauv qhov txwv thaum koj tau txais daim duab ntom ntom nrog ntau ntau cov npoo ntawm qhov vertices.
Kuj nug, Prim's algorithm siv rau dab tsi?
Hauv computer science, Prim cov (tseem hu ua Jarník's) algorithm yog tus siab hlob algorithm uas nrhiav qhov tsawg kawg nkaus spanning ntoo rau ib tug hnyav undirected graph. Qhov no txhais tau tias nws pom ib qho kev sib txuas ntawm cov npoo uas tsim ib tsob ntoo uas suav nrog txhua qhov vertex, qhov twg tag nrho qhov hnyav ntawm tag nrho cov npoo hauv tsob ntoo raug txo qis.
Lub sij hawm complexity ntawm insertion sort algorithm yog dab tsi?
Insertion kev yog ib qho ruaj khov xaiv nrog aspace nyuaj ntawm O (1) O (1) O (1). Rau cov npe hauv qab no, uas ob sorting algorithms muaj tib yam khiav sij hawm (tsis quav ntsej qhov xwm txheej tas li)?

Dab tsi yog lub sij hawm ncua sij hawm relay uas siv lub sij hawm RC Circuit Court?
Kev tsim tshiab ntawm lub sij hawm ncua relays siv hluav taws xob circuits nrog resistor-capacitor (RC) tes hauj lwm los tsim lub sij hawm ncua, ces energize ib txwm (instantaneous) electromechanical relay coil nrog cov hluav taws xob Circuit Court cov zis
Qhov txawv ntawm lub sij hawm lapse thiab lub sij hawm lapse yog dab tsi?
Ib qho hyperlapse, ntawm qhov tod tes, tsis muaj kev txwv li no: 'Nws ua rau lub koob yees duab txav mus rau ntau qhov deb,' Tompkinson hais. Hauv lwm lo lus, hyperlapse zoo ib yam li lub sijhawm ua haujlwm, tab sis nrog ntau qhov kev sib tw
Dab tsi yog lub sij hawm complexity ntawm pawg thawb ua haujlwm?
Rau tag nrho cov txheej txheem pawg ua haujlwm (push, pop, isEmpty, size), qhov kev ua haujlwm tsis zoo tshaj plaws tuaj yeem yog O (1). Peb hais tias ua tau thiab tsis yog vim nws ib txwm ua tau los siv cov pawg nrog cov sawv cev hauv qab uas tsis muaj txiaj ntsig
Lub sij hawm complexity nyob rau hauv cov ntaub ntawv qauv yog dab tsi?
Lub sij hawm complexity ntawm ib tug algorithm quantifies lub sij hawm npaum li cas los ntawm ib tug algorithm los khiav raws li ib tug muaj nuj nqi ntawm qhov ntev ntawm cov tswv yim. Ib yam li ntawd, Space complexity ntawm ib qho algorithm quantifies tus nqi ntawm qhov chaw los yog lub cim xeeb coj los ntawm ib tug algorithm khiav raws li ib tug muaj nuj nqi ntawm qhov ntev ntawm cov tswv yim
Koj txhais li cas compile lub sij hawm tas li hauv Java Dab tsi yog siv compile lub sij hawm tas li?
Compile-time constants thiab variables. Cov ntaub ntawv Java hais tias: Yog hais tias ib hom thawj zaug los yog ib txoj hlua txhais tau tias yog qhov tas li thiab tus nqi raug paub thaum lub sij hawm sau, lub compiler hloov lub npe tas li txhua qhov chaw hauv cov cai nrog nws tus nqi. Qhov no yog hu ua compile-time constant
