Linear Programming Teeb meem ( LPP ) muab cov txheej txheem ntawm kev nrhiav cov haujlwm zoo li no nrog rau / lossis cov txiaj ntsig uas yuav ua kom zoo dua qhov yuav tsum tau ua.
Hais lus, koj txhais li cas los ntawm LPP?
Linear programming (LP, tseem hu ua linear optimization) yog ib txoj hauv kev kom ua tiav cov txiaj ntsig zoo tshaj plaws (xws li cov txiaj ntsig siab tshaj plaws lossis tus nqi qis tshaj) hauv cov qauv lej uas nws yuav tsum tau muaj los ntawm kev sib raug zoo linear.
Ib yam li ntawd, koj txhais li cas los ntawm teeb meem kev thauj mus los? Cov teeb meem kev thauj mus los yog ib hom tshwj xeeb ntawm linear programming teeb meem qhov twg lub hom phiaj yog txo tus nqi ntawm kev faib khoom los ntawm ntau qhov chaw lossis keeb kwm mus rau ntau qhov chaw. Vim hais tias ntawm nws cov qauv tshwj xeeb cov txheej txheem simplex ib txwm tsis haum rau kev daws teeb meem kev thauj mus los.
Ua raws li qhov xav tau, cov kauj ruam ntawm LPP yog dab tsi?
Cov kauj ruam mus rau Linear Programming
- To taub qhov teeb meem.
- Piav txog lub hom phiaj.
- Txhais cov kev txiav txim variables.
- Sau lub hom phiaj ua haujlwm.
- Piav txog cov kev txwv.
- Sau cov kev txwv nyob rau hauv cov nqe lus ntawm kev txiav txim variables.
- Ntxiv cov kev txwv tsis pub dhau.
- Sau kom zoo nkauj.
Dab tsi yog qhov kev daws teeb meem tsis raug cai?
Ib tsis muaj kev daws teeb meem ntawm qhov teeb meem linear programming yog qhov xwm txheej uas lub hom phiaj ua haujlwm tsis kawg. Alinear programming teeb meem tau hais tias muaj unboundedsolution yog nws daws tuaj yeem ua tau loj heev yam tsis tau ua txhaum ib qho ntawm nws cov kev txwv hauv qhov teeb meem.

Dab tsi yog qhov teeb meem tsis yog linear?
Ib qho piv txwv ntawm qhov teeb meem tsis-linear isy=x^2. Yog tias koj pib nrog x = 1,2,3,4 qhov tshwm sim y = 1,4,9,16. Alinear teeb meem yog ib qho teeb meem uas daws tau los ntawm kev teeb tsa tsuas yog cov kab zauv sib npaug lossis cov kab sib npaug ntawm qhov sib npaug los daws. Ib qho kev qhia hauv cov variablesx1,, xn yog linear yog tias nws yog ntawm forma1x1 +
Dab tsi yog suav tias yog organic teeb meem?
Rau ib tug gardener, organic teeb meem yog ib yam dab tsi nrog cov organic tebchaw uas koj ntxiv rau cov av raws li kev hloov kho. Hauv cov ntsiab lus yooj yim, nws yog cov nroj tsuag decaying lossis tsiaj cov khoom. Qhov no feem ntau suav nrog compost, ntsuab manure, nplooj pwm, thiab tsiaj quav quav
Dab tsi yog qhov teeb meem ntawm lub teeb nyob rau hauv lub ntuj hmo ntuj hu ua?
Gegenschein, tseem hu ua Counterglow, oval thaj ntawm faint luminosity raws nraim rau lub hnub nyob rau hauv lub hmo ntuj. Lub thaj ntawm lub teeb yog li faint nws tuaj yeem pom tsuas yog thaum tsis muaj lub hli, nyob deb ntawm lub nroog teeb, thiab nrog lub qhov muag yoog rau qhov tsaus ntuj
Kev sib raug zoo ntawm lub teeb thiab teeb meem yog dab tsi?
Lub teeb thiab teeb meem cuam tshuam rau ib leeg hauv ntau txoj hauv kev. Kev sib cuam tshuam ntawm lub teeb thiab teeb meem txiav txim siab qhov tshwm sim ntawm txhua yam nyob ib puag ncig peb. Lub teeb cuam tshuam nrog cov teeb meem xws li emission thiab nqus. Cov nyhuv photoelectric yog ib qho piv txwv ntawm qhov teeb meem absorbs lub teeb
Puas yog khoov ntawm lub teeb tsis nyob ib puag ncig cov teeb meem?
Diffraction yog pom ntawm lub teeb tsis muaj zog tab sis tsuas yog thaum nthwv dej ntsib teeb meem nrog cov wavelengths me me (xws li cov khoom raug tshem tawm hauv peb cov huab cua). Diffraction yog qhov khoov ntawm nthwv dej ncig obstacles thiab qhib. Tus nqi ntawm diffraction nce nrog nce wavelength
