Ingqiqo algorithm kunye neempawu algorithm. iintlobo algorithm

Ingqiqo algorithm futhi indlela iimpawu zezinye iikhonsepthi zibalulekileyo kwinzululwazi yekhompyutha. Abantu abaninzi namhlanje, ngelo lizayo iphakade lobuchwepheshe computer, cinga ngento na kwaye uqale kancinci ngenxa yezizathu ezahlukeneyo, lokuhlolisisa iinkcukacha ngakumbi iziseko inzululwazi computer, ngexesha isizukulwana yangoku udlula le nto sele kwibakala wesithandathu.

Yintoni na?

Yintoni ingqiqo algorithm kunye neempawu algorithm?

Algorithm - yokulandelana ethile ngezenzo, oko kukuthi, umgaqo, kufuneka sijongane nazo yonke imihla, nangona ukuze singabi uyazi.

Man and algorithm

Ngokomzekelo, xa sicela umntu evela kumalungu eentsapho zabo ukuba bathenge into evenkileni, sibuza ukulandelelana yezenzo, okt namabali abaliswa yintoni iimveliso ezithile kufuneka athenge, yintoni nobungakanani yintoni na efunekayo ngamnye kubo. Ngoko ke, njengoko kutshiwo apha ngasentla, unikwa ulandelelwano ngokucacileyo amanyathelo, ezifana:

1. Jonga ivenkile ethile.
2. Fumanisa ukuba kukho into wathengisa isonka esimhlophe.
3. Ukuze ufumanise ukuba ingaba acocekileyo.
4. Ukuba iimpendulo zemibuzo-2 no-3 "ewe", ngoko kulo mzekelo, bathenga izonka ezibini.

Kakade ke, kusenokubonakala ngathi inkqubo abamaziyo esiqhelekileyo, yaye inkcazelo enjalo kakhulu voluminous. Kodwa enyanisweni, xa kufikwa yintoni na ingqiqo algorithm kunye neempawu algorithm kwinzululwazi mihla, kukho imiyalelo ukuba voluminous kakhulu ngakumbi, njengoko algorithm ngentla yenye elula.

Ubuchule endalweni

Wonke umntu unomphelo elisombulula inani elikhulu imisebenzi eyahlukeneyo, yiba ukuntsonkotha ezahlukeneyo, yaye ezinye zazo ezilula kangangokuba ingasombululwa ngokuzenzekelayo ngokupheleleyo, ngaphandle waze waqonda ukuba umsebenzi othile. Umzekelo: ukuba avale ucango kunye isitshixo, ahlambe, nidle isidlo sakusasa, ukondla usapho njalo njalo ..

Kodwa kukho ezinye iingxaki nelunzima kangangokuba abacinga ixesha elide kufuneka ukusombulula kubo, kwakunye yonge umgudu ekuqaleni ukufumana isisombululo, yaye kuphela emva koko ukuphumeza le njongo. Le misebenzi zezi: ukufunda ulwimi, ukufumana isixa esithile semali, kunye nabanye. Ngamanye amazwi, ukuba enze imisebenzi enjalo ifuna izenzo kakhulu entsonkothileyo kakhulu, xa kuthelekiswa indlela kufuneka agcwalise umsebenzi "kuthenga isonka", kodwa eneneni nkqu imisebenzi elula ukuba isonjululwe ngayo amanyathelo ezimbalwa.

Concept, iintlobo kunye neempawu

Xa uhlobo lwe ngolandelelwano oluthile yezenzo linokuchazwa inkqubo yokusombulula inani elikhulu imingeni abantu nayo kubomi bemihla ngemihla, yaye oku nolandelelwano imelwe kwi computer njengoko ingqiqo algorithm kunye neempawu algorithm.

Enye elaziwa zonke ke ngoko ngokuba algorithm Euclidian, esebenzisa leyo emiselwe, umahluli omkhulu oqhelekileyo integers ezimbini.

Kufuneka kuqatshelwe ukuba, ucinga ingqiqo algorithm kunye neempawu zayo, akuyomfuneko ukuba uyiqonde kakuhle izenzo ngokwabo, kodwa ke Enyanisweni, yintoni ukuze ukwenziwa. Ngoba kukho iimeko ezinjalo xa utshintsha umyalelo yezenzo kwi algorithm ekugqibeleni kusenokuba Order ayizukunyanzeliswa kwiimeko ezithile. Umzekelo, ukuba uya evenkileni, ekuqaleni algorithm iyafana kulandelayo:

1. Yiya evenkileni.
2. Khetha isonka.

okanye:

1. Khetha isonka.
2. Yiya evenkileni.

Ukuba sicinga algorithm yokugqibela, ngoko ke isonka ekuqaleni uwunyulileyo, kwaye ke siya umsebenzi kakuhle echazwe kule venkile, kwaye ukuba ngenene kuthi kufuneka isonka akukho nto, ngoko kuloo meko baye bakha algorithm ekugqibeleni uya Order ayizukunyanzeliswa.

iintlobo

Iintlobo ubuchule zezi zilandelayo:

• Nokungazinzi koqoqosho. Algorithm, apho isakhiwo elibujikele ekhoyo, ngamanye uphindaphindo imisebenzi eyahlukeneyo.

Into ekufuneka uyazi?

Okokuqala kukho indlela yokwenza algorithm, kuyimfuneko ukumisela umyalelo, leyo iimeko yokuqupha umsebenzi othile, yaye kufuneka sazi ukuba. Ngokwawo, i algorithm ulandelelwano anesiphelo izenzo sele ekucombululeni umsebenzi othile, nto leyo esiyifumana ulwazi sokuqala ukuya result ethile. Kuyo nayiphi na imeko, igunya yophuhliso algorithm yezenzo bobabo umntu, yaye benza ekwenzeni ezi zenzo sele abantu ezahlukeneyo okanye zonke iintlobo izixhobo, ezifana Hewana, iirobhothi, iikhompyutha, izixhobo phambili, kwaye nabanye zokudlala bafunde ukwenza kubo kutshanje.

indaba

Al-Khwarizmi - lo ngumntu wokuqala ochazwe ingqiqo algorithm kunye neempawu algorithm. Basekuhlaleni le ngcamango wazuza emva kwexesha elithile, xa ifumene intsingiselo ngokubanzi baza baqalisa ukukhangela nayiphi na imithetho ngqo isenzo esithile. Ukuza kuthi ga ngoku, le ngcamango ziqondeka abaninzi njengenye iikhonsepthi ezibaluleke kakhulu kwinzululwazi ezifana kwinzululwazi yekhompyutha, ngaphandle apho kuba nzima ukuba nomfanekiso.

Sam Al-Khwarizmi wayephila BC ngenkulungwane IX, kwaye kubalulekile ukuphawula ukuba i-Arabic lokuqala yokuqala, echaza imisebenzi yakhe izibalo sele ayaba, kodwa kukho inguqulelo, ngawo Western eYurophu ekugqibeleni uziqhelanise nenkqubo wokugqibela ngokokuma notation, kunye nemigaqo esisiseko ukwenza imisebenzi eyahlukeneyo arithmetic.

Le Isazinzulu bafuna ukuqinisekisa ukuba imithetho ezithe zavela kubo, baba icace kakhulu nawuphi na umntu ukufunda nokubhala. Ukuphumeza oku an ubudala xa kungekho umqondiso yinxalenye zemathematika, kwakunzima gqitha, kodwa nzulu wakwazi kwiincwadi zakhe ekugqibeleni ukuphumeza i ecacileyo kwaye ngexesha elinye engqongqo imiyalelo yomlomo, njengoko apho umfundi akazange akwazi ukuphepha imisebenzi eyabelwe, okanye ukutsiba izenzo ezithile .

Inguqulelo yesiLatini abangabasemisebenzini nzulu sentlalo kwenye incwadi eyodwa ebizwa ngokuba "watsho Algorizmi." Ekubeni ngokuthe ngcembe abantu baqala ukulibala malunga nexesha "Algorizmi" Ungumbhali imithetho enjalo, kangangokuba waqalisa ngokuba algorithms imithetho. Ngoko ke, ngokuthe ngcembe, "wathi Algorizmi" atshintshileyo babe "algorithm ifundeka."
