Izindlela kuchaza algorithm kanye nezinhlobo algorithm

Nge elithi "algorithm" baye babhekana. Phela, uhlobene eduze ezimpilweni zabantu. Kuyini lokhu? Yiziphi izindlela ezahlukene echaza algorithm, izinhlobo algorithm? Yiziphi bona? Lesi sihloko sizosisiza ukuba baqonde yonke le wafaka konke endaweni yayo.

Algorithm: umqondo, izinhlobo, izindlela wokuchaza

I gama lisho ukulandelana ecacile futhi esiqondile izinyathelo ezilula ukuthi umculi ngizodabula ukuze baxazulule le nkinga phambi kwakhe. Igama elithi "algorithm" has kwaqala igama usosayensi odumile Oriental nesazi sezibalo Al-Khwarizmi. Nguye washayelwa zonke imithetho nokwenza izibalo. Ekuqaleni lo mqondo saqonda imithetho kuphela eziphathelene ezinkulu imisebenzi emine izibalo ukwenziwa izinombolo. Futhi kuphela ke umqondo iye yasetshenziswa ukuze ubheke ukulandelana izinyathelo eziholela ikhambi yenkinga. Lapho Computing inqubo idatha kukhona izinto okuyinto algorithm sisetshenziswa. Lapho yokuxazulula le nkinga iyabheda kokubala idatha yoqobo aguqulwa ku Amaphuzu.

Uhlelo lokubhalwa kohlelo algorithm kuyinto lokudala kakhulu, naphezu alula. Uma ungenza umuntu akwazi ukwenza futhi imishini. Futhi namhlanje akusiyo kuphela ikhompyutha, kodwa futhi amafoni, amaphilisi, ezikhumulweni ngisho ukugeza imishini ukuze abenzi ikhofi.

Ngesicelo-Inthanethi ungathola eningi ukwaziswa okuwusizo, kodwa kusamele behlangene. Ngakho-ke, lokhu icacisa zonke ezibalulekile.

Yiziphi izindawo eziyisisekelo algorithm?

1. Izincazelo. Le mpahla libizwa Determinism. Luhilela ukuthola umphumela ukubala, okungukuthi ocacile lapho ecacisa kwedatha yokufaka ekubaleni. Le mpahla unika inqubo kokwenza lokukhanda. Alukho ulwazi olwengeziwe futhi iziyalezo mayelana msebenzi. Kufanele kube lutho ngaphandle kokubonisana nomkayo.

2. eMiseni. Le mpahla kusho ukuthi i-algorithm kufanele kube efanelekayo ukuxazulula eziningi lafananako zezinkinga. Baseline kuleli cala bangase ezikhethiwe kusuka kunoma iyiphi indawo ngokuthi isicelo.

3. Ukusebenza Ngempumelelo - impahla elikhombisa ukuthi umthombo ulwazi, okuyiwona elinikeziwe inqubo ukuhamba komsebenzi kumelwe ibhekane inombolo ezilinganiselwe izinyathelo, bese ayeke, enika elamukelekile.

4. readability - kulapho inqubo Computing yahlukaniswa ngezigaba. Futhi kungenzeka kokusebenza kwabo akuyona ungaqiniseki. Lapha, ngamunye isinyathelo okwalandela uyabulawa kuphela uma langaphambilini eseqedile ngokuphelele.

Izindlela echaza algorithm aqondwa bonke

Algorithms kufanele yentiwe ngalokusemtsetfweni ngemithetho ethile ngosizo amathuluzi athile. Izindlela eyinhloko echaza algorithm: asebentisa emagama, ifomula okulotshwayo, algorithmic, kanye ne-software sokuqhafaza.

ifomu Verbal - irekhodi ngolimi angokwemvelo. Wazamukela ezivamile ingasaphathwa, ngoba wordy kakhulu. Futhi okwamanje awunazo ukubonakala. amazwi ncazelo engabulawa semthethweni futhi ekudingayo kungahunyushwa ambiguously.

ifomu Formula okulotshwayo kancane elula kakhudlwana. Lapha amagama kunezelwa zezibalo ezingaba kokubili usizo futhi, Ngakolunye uhlangothi, ukudida ukufunda umuntu. Ezinye izindlela wokuchaza algorithm zibelula.

Izindlela echaza algorithm kubasebenzisi computer

Algorithmic ukuqopha indlela esekelwe mbumbulu. Lona ikhodi ukuthi akufane isakhiwo ulimi lokwakha izinhlelo, kodwa imiyalo banikwa ngolimi yemvelo, namazwi samanje zezibalo. Pseudocode - Ulimi semi semthethweni. Le ndlela kakade ocacile kakhulu, ikakhulukazi program.

Izindlela echaza algorithm ezichazwe ngenhla abangu semthethweni ngokugcwele whereupon Uhlelo notation ozalwa. Isebenzisa omunye izilimi eziningi zokuhlela, okulotshiwe futhi ukulandelana efanayo izinyathelo ukwenza. Ikhompyutha ofunda nabo ngamunye ngamunye futhi ubulala imiyalelo, eyagcina kuholela esiphethweni sendaba.

Indlela ethandwa kakhulu wokuchaza

indlela Graphic wokuchaza algorithm got ethandwa kakhulu ngenxa yokuthi icacile. Ibizwa nangokuthi wesifunda izindlela block ukuphuma. Uyini ngempambano? Leli cebo kuyinto elwa sokuqhafaza algorithm. isinyathelo ngasinye processing idatha, lihunyushwe ngokuthi sibalo Jomethri, ngokuthi iyunithi. iyunithi ngalinye has a ukumisa okuyinto kuncike hlobo lomsebenzi owenziwayo. Igama kanye nohlu izinhlamvu, ngezindlela ezihlukahlukene futhi ayilingani, kanye ukubonisa imisebenzi kuchazwa amazinga. Uma uthatha zonke izindlela ezinkulu algorithm echaza, lena ezisobala kakhulu.

ekubaleni izinqubo

Izindlela echaza algorithm usebenzisa flowchart lokucabanga izinhlobo ezintathu eziyinhloko kokubala izinqubo: yomugqa, ekhelini kanye eyindilinga.

Line - kuyinqubo lapho isinyathelo ngasinye wenziwa ukuxazulula inkinga ngokulandela inqubo.

Ekhelini - inqubo yokubala, lapho ngokuya ngomthombo nolwazi Lesisemkhatsini, futhi ukuqinisekiswa imiphumela izimo okunengqondo Ukukhetha engaphansi isiqondiso.

algorithm lokujikeleza yakhiwa eyodwa noma ngaphezulu koyedwa umjikelezo, isb Computing isabelo siphindwa sebuningini izikhathi. Imijikelezo Esekela kungenzeka predetermined ezinikezwa futhi akuqinisekile. Kuye ukuhambisana nanoma yimiphi imibandela kunqunywa inani ezinikezwa. Ngaphezu kwalokho, isimo kungaba ihlolwe ekuqaleni umjikelezo noma ekugcineni.

Izindlela algorithm echaza isobala, kodwa kunemithetho ethulwa kubo.

Imithetho ngokudala algorithm

Okokuqala, ukuthuthukiswa ye-algorithm kudingeka ucele eziningi izindawo umsebenzi. Ukumeleleka ehlelekileko izinto ezifana - lena idatha. I-algorithm iqala nge iqoqo idatha ngokuthi okokufaka, kokuwaguqulela ku okukhipha - okukhiphayo. Lokhu kungase kusetshenziswe noma iyiphi izindlela echaza algorithm. Izakhiwo algorithm kufanele sihlonishwe.

Umthetho wesibili: ukuze algorithm wayegila, idinga inkumbulo. It ibekwe okokufaka, Lesisemkhatsini okukhiphayo. Memory ngokwawo leyehlukene, okungukuthi, sinetigaba ahlukene - amaseli. Lelo ngqamuzana ukuthi unegama, ngokuthi kwenombolo.

Umthetho wesithathu - kuba leyehlukene. Lonke algorithm kufanele akhiwe kusuka imisebenzi ngabanye, inani okuyinto kumelwe nakanjani babe elinganiselwe.

Kufanele kuqashelwe ukuthi kukhona into enjalo njengoba i-algorithm elisizayo, okuyinto yakhelwe kusengaphambili bese isetshenziswa kwenye imisebenzi algorithmic. Kungase futhi ukubizwa inqubo asizayo.

Umqondo algorithm, izakhiwo, izindlela ukuchaza - ngaphandle kwakho konke lokhu emkhakheni computer noma kuphi. Lona isizinda lapho wonke computer science kwamasabatha.
