Isigqibo uhlelo. yokuhluzana

Ukohluka bezinto ezinokuzuzwa iinkqubo ezinikezelwa yi iinkqubo zekhompyutha mihla ubulula kunye nokufumaneka lonke lwaseNtshona Koloni ziba izisombululo imisebenzi eyahlukeneyo. Le miba entsonkothileyo isonjululwa ngokukhawuleza kwaye musa ukuba iindleko ezongezelelweyo kuzo zombini ixesha kunye nomgudu ngokwengqondo uhlelo. Nkqu abancedisi ultra-eluncedo ukusebenza nge nomkrwelo ngaphandle nokwenziwa ngokusekelwe kumsebenzisi ukuba uqhelene kuthi nangona bekukho ikhondo inzululwazi yekhompyutha kwisikolo samabanga aphakamileyo.

Ukufumana yokuphunyezwa naziphi na izimvo zayo ikhowudi, uhlelo kuya kufuneka ukuba benze inkcazo-oganogram ngenkqubela isisombululo. Kuye kudala babecinga up imithetho kunye neenkqubo ukuzoba up ubuchule. Kule ncwadi algorithm ichaza indlela imiyalelo ngqo noluqondakalayo ukuphumeza ulandelelwano ngokungqongqo ethile imisebenzi. Ngenxa ukuphunyezwa wabo wokukora nempumelelo okanye ukuba isisombululo kule ngxaki.

igama lakhe, igama elithi "algorithm" yathiywa emva njengomntwana onengqondo Uzbek Al-Khwarizmi. Umsebenzi Wayo "imbali yokalo emileyo" yaba sisiseko imithetho lwemisebenzi izibalo kumanani, kwaye makusetyenziswe imithetho ngokwabo yaziwa ngokuba ubuchule. Nge Ukongeza, ukuthabatha, ukwahlulwa phinda yembali yehlabathi yaqala kweenkqubo.

Uluhlu ezahlukeneyo iindlela ezahlukeneyo zokusombulula imisebenzi efanayo kukhutshwe yokuhluzana. Ufana nihambe kwisangqa ukuphumeza injongo ethile. Nodweliso lwenkqubo i robin nxazonke ubunzima enye, oko kukuba ephosakeleyo yokuba uyilo okanye inkinga yabo computer "ngumkhenkce," oko kukuthi, ukuya ukwenza inani olungenasiphelo amaxesha imisebenzi efanayo.

Ngokutyhilwa mihla algorithm elibujikele - yinto yemihla izenzo ezithile ukuba ngokuphindaphindiweyo ukutshintsha idatha yoqobo. Ngokwawo, le nkqubo yenziwe ngaphandle kobunzima ezithile. algorithm Zijika ludibaniso linear le algorithm kunye algorithm branched.

Nangona lula iliso kwaye kubekho iingxaki ezithile efanayo olu hlobo algorithm luphawulwa ubukho ezininzi kweentlobo zabo. robin Round lisetyenziswa ngokubeka ukusebenzisa iintlobo ezintathu ezahlukeneyo mijikelo. Ngamagama zabo inokubonwa ngokobunjani nokumila imisebenzi.

Cycle ne Imeko ibandakanya iimeko ekutshekisheni ukuba ukuqaliswa algorithm phambi kokuba uluhlu lwemisebenzi (uqulunqe njenge algorithm yomgama). Nge umjikelo postcondition wahlukile kowangaphambili, kuloo meko lukhangelwa emva kokwenza component yomgama. Kuba parameter umjikelo luphawulwa kukho umzobo othile, ukwanda okanye ukuncipha kunye nokuphunyezwa uluhlu lwemisebenzi. robin Round kunye imitha, maxa wambi ibizwa ngokuba uhlobo mijikelo.

Ngaphandle elula ukuphunyezwa kwale hlobo algorithm, iinguqulelo ezimbini ngaphantsi elinzima zonke ulwimi lokuprograma mihla sinengqokelela yayo ethile imiyalelo ukuqulunqa nemijikelo. Kulo mzekelo, ungenza omnye kumzimba zenkqubo ukusuka kwelinye ukuya imijikelo eziliqela, ngokuxhomekeke kubuzaza bengxaki ukuba isonjululwe.

Ngokwabo yokuhluzana ndafumana twa enkulu kwinkqubo kweenkqubo. Ukongeza kwiinkqubo ezithile ukuba enze imisebenzi ethile, kukho imijikelo engenanto. umsebenzi wawo ukuba ukudala hluleka.

Cycle ngokwayo lingakumela mabinzana mabini eqhelekileyo. Umzekelo, ukuba sele yokuhluzana mazwi alandelayo:

- sisithethe eqhiyeni;

- Ukuba itshefu emdaka, ngoko hamba uye ekuqaleni.

Unakho ukucinga eninzi imizekelo ezinjalo. Kakhulu ohlukeneyo imijikelo azibonakalisa ukwenziwa kwemisebenzi imizobo, nkqu ukudaleka yeraster kwi isikrini ziiprogram umjikelo ngetyala. Ma, iingxaki ubhalo, ezinkulu kunye neenkqubo yokonwabisa akakwazi ukwenza ngaphandle iingenelo ubuchule elibujikele.
