Yengetiwe indlela: izinhlobo ezinkulu algorithm kanye yezamakhompyutha

Inani elikhulu izinkinga zezibalo ezihlobene ngokuthola ulwazi basakaza Ukuboshelwa emkhathini. Sikhuluma zezokwazisa focus womhlaba, ngoba kuzo kungenzeka ukukala namagugu adingekayo ezindaweni ezithile. Ukuze kuxazululwe lezi zinkinga ngokuvamile usebenzise eyodwa noma enye indlela yengetiwe.

definition

Yengetiwe kuyindlela kokubala amanani Intermediate ngoba amanani isethi etholakalayo yamanani leyehlukene. Izindlela ezivame kakhulu yengetiwe zimi kanje: Indlela ephambene ibanga kwesamba, ebusweni mkhuba futhi kriging.

izindlela eziyisisekelo yengetiwe

Ngakho, sihlolisise indlela yokuqala, essence yayo itholakala ithonya amaphuzu ukuthi sesiseduze isihlobo kulinganiselwa ukuthi indawo eyengeziwe. Njengoba yengetiwe indlela kuhilela Ukukhetha kusuka sendawo endaweni ezithile iphuzu othize, has nethonya elikhulu kuso. akhethiwe Ngakho esiphezulu search uhla noma inani lamaphuzu ukuthi zitholakala eduze iphuzu elithile. Ngaphezu kwalokho ukulungiswa sinikezwa nesisindo iphuzu ngalinye ethile, okuyinto ibalwe ngokwendlela ibanga kusuka iphuzu inikezwe. Kuphela ngale ndlela bungatholakala ngokunikelela enkulu iphuzu esiseduzane kule ukuphakama interpolated uma iqhathaniswa amaphuzu kude kude isethi.

Eyesibili yengetiwe indlela isetshenziswa uma kukhona isithakazelo ukuba abacwaningi jikelele Amathrendi ebusweni. lingasetshenziswa Ngokufanayo indlela yokuqala ukuze mkhuba iphuzu, okuyizinto ngaphakathi surface kusengaphambili. Lapho ukwakha eziningi isilinganiselo engcono esekelwe zezibalo (Polynomials noma splines). Ngokuvamile, sebenzisa indlela izikwele okungenani esekelwe zibalo ka ukuncika nonlinear. Indlela kusekelwe esikhundleni Curves nezinye izinhlobo ukulandelanisa zezinombolo uthayiphe elula. Ukwakha umkhuba ukubaluleka kwamanzi ngamunye kumele sifakwe esikhundleni phakathi kwesibalo. Imiphumela iba yinhlanganisela yokukhandleka value ehlukile enikezwa isixazululo interpolated (iphuzu). Ukuze zonke ezinye amaphuzu yenqubo uyaqhubeka.

Enye indlela yengetiwe ngenhla, kriging inqubo yengetiwe sihlinzekela nokwenza, ukuthatha njengesisekelo ubunjalo lezibalo ebusweni.

Ukusebenzisa yengetiwe quadratic

Kukhona elinye ithuluzi ukucacisa maphuzu - indlela yengetiwe quadratic, ngokuyisisekelo okuyinto esikhundleni umsebenzi ngesikhathi kwenkathi ethile a parabola quadratic. Ngakho extremum yayo ibalwa analytically. Ngemva indawo yakhe eseduze (ubuncane noma umkhawulo) kumele imiswe isikhawu ezithile amagugu, bese ukucinga ekutholeni isixazululo ukuze uqhubeke. Ngokwenza lokhu inqubo futhi, kungenzeka, usebenzisa i inqubo iterative ithuba lokucwengisiswa ukubaluleka kwalesi kwesibalo nomphumela nge ukunemba predetermined ekwakhiweni inkinga.
