Indlela simplex kunye nesicelo yayo

Naziphi na iinjongo isisombululo yemizobo ye iinkqubo yomgama imisela ukuba isisombululo elifaneleke (elilelona) naziphi na iingxaki ezinxulumene izele kwinqanaba (indawo kwikona okanye indawo). Le ngcamango isekelwe indlela aljibra jikelele simplex ukuba iingxaki iingxaki, nto leyo ukusombulula ngenene naliphi na umsebenzi lokuprograma.

Ukubuyela kule ndlela yokubala ukuba zokusombulula iingxaki kwizisombululo ezisebenzisa indlela simplex iinkqubo yomgama, kuyimfuneko ukuba enze inkcazo yazo zonke iingongoma egqithiseleyo le ndawo, usebenzisa iindlela algebra. Ukuze wenze le yenguqu kuyimfuneko ukuba azise nayiphi na ingxaki iprogram in ifomu (ekwabizwa ngokuba eziphefumlelweyo).

Ukuze wenze oku, yenza la manyathelo alandelayo:

• iguqulelwa equity zonke izithintelo ukungalingani (emayiphunyezwe ukuqaliswa variables ezintsha olongezelelweyo);
• nokukhulisa ingxaki ukuguqula ukunciphisa le ngxaki;
• kufuneka afumane izinto engasiyiyo-, iguqulela kubo bonke free.

Afunyenwe ngenxa yazo zonke iinguqu imilo iintlobo umgangatho wemisebenzi iya kumisela isisombululo esisiseko. Nto leyo, sichaza ngokucacileyo zonke iingongoma kwikona isithuba. Kamva, le indlela simplex kuya kukunceda ufumane simse zonke isiseko ezifunyenweyo.

Eyona nto ibalulekileyo ezisebenza indlela efanayo yokusombulula imisebenzi aljibra practice - leyo ukuphucuka oluthe gqolo ukusebenza kwesicwangciso, isiphumo yayo ekufezekisweni kweenjongo kunye izikhonkwane ngempumelelo enkulu. Eyona nto ibalulekileyo ukuyenza ukuze ufumane iziphumo ezinqwenelekayo - ilungile ukuliphumeza ngohlobo zemathematika kunye software.

Isiphumo lonke uphuhliso kufuneka ibe indlela simplex, nto leyo inkqubo processing ezizodwa, ezisekelwe phezu ukuphucuka okuqhubekayo izigqibo ngalunye olulandelayo. Oku kwenzeka xa kuthelekiswa pairwise onke amanqaku kwi-moya, kwaye ekufumaneni egqibeleleyo.

Kuye kudala wabonisa ukuba bonke ukukhangelwa isisombululo kangangoko (ukuba ikhona) lugqityiwe iphelele kwaye anesiphelo inani amanyathelo. Kuphela ngaphandle, nto leyo ayinakuluphatha indlela simplex - i "ingxaki bonakele." Ngenxa yoko kukho ekuthiwa "ngokwenzekayo", nto leyo ekhokelela ukuba uphindaphindo lomgadi inani elifanayo engenasiphelo amaxesha imisebenzi.

indlela simplex yasungulwa ngo-1947. "Umzali" baso yezibalo ukusuka kwi US Dzhordzh Dantsig. Ngenxa yokuba le ndlela simplex unembali ende ezinjalo, namhlanje yenye kakhulu ukufunda yaye eyona eyiyo ukukhangela izisombululo kangangoko ukuba naziphi na iingxaki abajongene nazo umntu.

indlela noun Stepwise lula kakhulu yonke imisebenzi yoluntu. Ingasetyenziswa omabini amacandelo yenzululwazi kunye nezoshishino. ukusetyenziswa kwayo kabanzi kuya kunceda ukwenza izisombululo ngokwezibalo oluchanekileyo afanelekileyo iingxaki ezintsonkothileyo.
