Topological sorting rau Directed Acyclic Graph (DAG) yog linear xaj ntawm vertices xws li rau txhua qhov taw qhia ntug uv, vertex u los ua ntej v hauv xaj . Rau piv txwv , a topological sorting ntawm cov duab hauv qab no yog "5 4 2 3 1 0". Yuav muaj ntau tshaj ib topological sorting rau ib daim duab.
Ib yam li ntawd, kev siv topological sorting yog dab tsi?
Ib qho kev siv ntawm topological sorting yog inscheduling ib theem zuj zus ntawm cov hauj lwm. Cov hauj lwm yog sawv cev los ntawm kev sib tw, thiab muaj ntug ntawm x rau y yog tias txoj haujlwm x yuav tsum ua kom tiav ua ntej txoj haujlwm y tuaj yeem pib.
qhov twg vertex yog dab tsi? Hauv kev lej, thiab tshwj xeeb tshaj yog nyob rau hauv graph theory, a vertex (plural ntsug ) los yog node yog lub fundamentalunit uas graphs yog tsim: ib tug undirected graph muaj asset ntawm ntsug thiab ib txheej ntawm ntug (unordered khub ntawm ntsug ), thaum ib daim duab qhia muaj ib txheej ntawm ntsug thiab ib txheej ntawm arcs
Nyob rau hauv txoj kev no, pes tsawg topological orderings muaj?
Nws muaj 2 topological kev txiav txim : 3. Xav txog cov duab tsis qhia hauv qab no uas yog sawv cev los ntawm nws qhov adjacencymatrix.
Nws txhais li cas rau daim duab ua acyclic?
Ib acyclic graph yog a daim duab tsis muaj daim duab lub voj voog. Acyclic graphs yog bipartite. Txuas nrog acyclic graph yog lub npe hu ua tsob ntoo, thiab tejzaum nws raug txiav acyclic graph yog hu ua hav zoov (piv txwv li, sau ntoo).

Dab tsi yog qhov sib piv thiab piv txwv?
Inverse proportion. Inverse proportions tshwm sim thaum ib tus nqi nce thiab qhov txo qis. Piv txwv li, ntau tus neeg ua haujlwm ntawm txoj haujlwm yuav txo lub sijhawm los ua kom tiav cov haujlwm. Lawv yog inversely proportional
Dab tsi yog txhais los ntawm lub sij hawm dissociation thiab dab tsi yog ib qho piv txwv ntawm cov khoom uas dissociates?
Dissociation, nyob rau hauv chemistry, sib cais ntawm ib yam khoom mus rau hauv atoms los yog ions. Thermal dissociation tshwm sim ntawm qhov kub thiab txias. Piv txwv li, hydrogen molecules (H 2) dissociate rau hauv atoms (H) ntawm kub heev; ntawm 5,000 ° K txog 95% ntawm cov molecules hauv cov qauv ntawm hydrogen yog dissociated rau hauv atoms
Dab tsi yog qhov txawv ntawm instantaneous thiab nruab nrab ceev dab tsi yog qhov piv txwv loj tshaj ntawm kev ceev ceev?
Qhov nruab nrab ceev yog qhov ceev nruab nrab ntawm lub sijhawm. Instantaneous ceev yuav yog qhov ceev txhua qhov muab tam sim ntawd hauv lub sijhawm ntawd, ntsuas nrog lub ntsuas ntsuas lub sijhawm
Dab tsi yog qhov txawv ntawm microevolution thiab macroevolution Dab tsi yog qee qhov piv txwv ntawm txhua tus?
Microevolution vs. Macroevolution. Piv txwv ntawm cov kev hloov microevolutionary no yuav suav nrog kev hloov ntawm hom xim lossis loj. Macroevolution, piv txwv li, yog siv los hais txog kev hloov pauv ntawm cov kab mob uas tseem ceeb txaus uas, dhau sijhawm, cov kab mob tshiab yuav raug suav tias yog hom tshiab nkaus xwb
Qhov piv txwv ntawm cov txheeb ze yog dab tsi?
Cov cheeb tsam loj ntawm qee cov ntsaum, muv thiab wasps yog lwm cov piv txwv nrov ntawm kev xaiv cov neeg ua haujlwm. Hauv ntau lub tebchaws no, poj huab tais yog tib tug poj niam uas yug dua tshiab. Lub tswb nrov yog lwm qhov piv txwv nrov ntawm kev coj cwj pwm tsis zoo uas txhawb nqa los ntawm kev xaiv cov phooj ywg
