Cov kaum point theorem hais tias yog qhov siab tshaj plaws lossis qhov tsawg kawg nkaus muaj, nws yuav tshwm sim ntawm a kaum point ntawm thaj av no ua tau.

Ua kom qhov no nyob rau hauv kev txiav txim siab, dab tsi yog txoj kev ntawm kaum point?

Cov kaum cov ntsiab lus yog cov vertices ntawm cheeb tsam ua tau. Thaum koj muaj daim duab ntawm cov kab ke ntawm qhov tsis sib xws, ces koj tuaj yeem saib daim duab thiab yooj yim qhia qhov twg kaum cov ntsiab lus yog. Daim ntawv ceeb toom tias txhua tus kaum point yog qhov kev sib tshuam ntawm ob kab, tab sis tsis yog txhua qhov kev sib tshuam ntawm ob kab yog a kaum point.

Kuj Paub, Dab tsi yog lub ces kaum ntawm daim duab? A ces kaum yog ib hom duab rau a daim duab uas muaj txoj kab nqes sib txawv ntawm ob sab. Ntawm no, qhov derivative ntawm x = 0 yog undefined, vim hais tias txoj kab nqes ntawm sab laug yog 1, tab sis txoj kab nqes ntawm sab xis yog −1.

Dab tsi yog txhais los ntawm kev daws teeb meem?

Txhais lus Kev daws teeb meem . A kev daws teeb meem yog cov txheej txheem ntawm qhov tseem ceeb rau qhov kev txiav txim siab hloov pauv uas txaus siab rau txhua qhov kev txwv hauv qhov teeb meem optimization. Cov txheej txheem tag nrho kev daws teeb meem txhais cov ua tau thaj tsam ntawm qhov teeb meem.

Dab tsi yog maximization hauv linear programming?

Txhais: Linear programming hais txog kev xaiv qhov zoo tshaj plaws lwm txoj hauv kev los ntawm cov kev xaiv muaj, uas nws lub hom phiaj muaj nuj nqi thiab kev txwv tsis pub muaj peev xwm qhia tau tias yog kab tawm kev ua lej. Maximization Case: Cia peb nkag siab qhov qhov siab tshaj plaws rooj plaub nrog kev pab ntawm ib qho teeb meem.
