Yuav ua li cas yog algorithms thiab dab tsi yog lawv rau?

Nyob rau hauv beginners thiab inexperienced programmers feem ntau tshwm sim rau lo lus nug: "Yuav ua li cas yog lub algorithms thiab dab tsi yog lawv rau?" Tab sis cov tswvyim no yog maj mam thiab nkag mus rau hauv oblivion, tab sis nws yog tseem tseem ceeb. Thaum koj tsim tau ib tug loj coj mus muag tej yaam num tsuas yuav tsis ua li cas tsis algorithms. Thiab ua ntej koj pib programming, nws yog zoo dua kom to taub lawv, thiab xwb ces npaj mus rau lub tswv yim ce. Txawm tias cov tswvyim no yog txuam nrog rau cov creation ntawm software rau ib tug PC, tab sis nws yog dav nyob rau hauv lub neej txhua hnub. Qhov tsab xov xwm no yog ib qho piv txwv ntawm dab lub algorithms nyob rau hauv lub neej tiag tiag.

Nyob rau hauv computer science,

Tam sim no peb nrhiav tau tawm yog dab tsi algorithms nyob rau hauv computer science thiab programming. Nyob rau hauv cov tswvyim no dag txheej txheem, siv uas koj tau sai thiab yooj yim kom daws tau qhov teeb meem. Raws li ib qho piv txwv, muab xam rau ntawm ib tug mis. Ua li no yuav tsum tau ua raws li nram no cov kauj ruam:

• Sau thawj zaug cov ntaub ntawv uas yuav tsum tau rau cov lus teb.
• Ua suav.
• Sau cov kev tshwm sim los yog nyob rau hauv lub computer screen, los yog nyob rau lwm yam xov xwm
  (Xws li daim ntawv).

hom

Algorithm nyob rau hauv computer science nyob rau hauv tsos yuav ua tau nyob rau hauv cov nram no hloov:

• Graphically (raws li ib tug txheej ntawm kev units).
• Phased ntawv nyeem cov lus piav qhia.

Nyob rau hauv thawj rooj plaub uas nws muaj lub tsev blocks, cov tsos ntawm cov uas yog tswj los ntawm GOST Serial No. 19.701-90. Piv txwv li, ib tug yooj yim lub lag luam yuav ces yuav tshwm sim nyob rau hauv daim ntawv ntawm ib tug duab plaub, thiab xaiv mob - ib tug pob zeb diamond.

Sau kom tiav kev qhia txog yog tsis yog li ntawd tshwm tag thiab thiaj li yog siv ntau tsawg zaus. Nyob rau hauv tsos nws tsa ib txwm bulleted daim ntawv teev nrog cov zauv los yog cov tsiaj ntawv. Raws li cov qauv piav qhia qhov txawv linear thiab branched. Cov kev xaiv thawj yog npaum li cas rarer. Qhov txawv nruab nrab ntawm lawv yog tias nyob rau hauv lub caij nyoog kawg no cov ntaub ntawv muaj branching chav nyob thiab tsis paub hais tias cov xov tooj ntawm pawg kom tau zaum kawg tshwm sim.

lub neej tiag tiag

Tam sim no cia tus nrog lub fact tias xws li algorithms nyob rau hauv lub neej tiag tiag. Nyob rau hauv qhov kev npaj ntawm ntau yam tais diav hostess yuav tsum daim ntawv qhia. Piv txwv li, nyob rau hauv qhov kev npaj ntawm cov nplej zom koj yuav tsum tau ua raws li nram no ib theem zuj zus ntawm kev ua:

• Nqa dej rau ib tug boil.
• Ntsev nws.
• Nqus nplej zom.
• On tsawg tshav kub, stirring lawv, coj mus rau lub rwj.
• Tom qab lawv siav, drained.
• Ntxiv rau qhov butter.
• Mix kom txog thaum uniform.

Lub tais yog npaj txhij. Yog hais tias koj saib nyob rau nws los ntawm lub qhov muag ntawm tus programmer, nws yog feem ntau ib tug linear algorithm, sau nyob rau hauv ib tug tabular hom. Yog li ntawd nws tsis yog li ntawd tsawg nyob rau hauv peb lub neej piav ntau zog ntxiv cov tswvyim no yog pom. Peb cia li siv tau thiab tsis txawm paub txog nws.

es tsis txhob ntawm cov lus xaus

Nyob rau hauv ntau qhov chaw ntawm tib neeg kev ua si xws tswvyim yog siv raws li ib tug algorithm. Cov ntaub ntawv siv tshuab - ib tug ntawm lawv. Ntxiv mus, lub feem ntau nto moo. Puas muaj li ib theem zuj zus ntawm kev ua ub no yuav zoo heev piv cov txheej txheem ntawm kev tsim ib software khoom thiab txhim kho nws zoo. Nws yog zoo li ib lub lag luam txoj kev npaj nrog kev tsim kho ntawm ib tug nroj tsuag los yog Hoobkas. Thaum koj tsim tau tej yam yooj yim cov kev pab cuam muaj peev xwm yuav ua tau tsis tau nws, tab sis thaum loj software tsim - tsis muaj nws nyob qhov twg. Nws yuav yog yuav generalized los yog ncauj lus kom ntxaws, tab sis nyob rau hauv txhua rooj plaub nws yog.
