Abstract: - Qhov teeb meem ntawm tus neeg muag khoom mus txawv tebchaws ( TSP ) yog ib qho ntawm cov teeb meem uas tau kawm ntau tshaj plaws hauv kev suav lej thiab kev ua kom zoo dua qub. Nws kuj tseem suav hais tias yog chav kawm ntawm NP- ua tiav cov teeb meem kev ua kom zoo dua qub.
Kuj paub, TSP yog dab tsi hauv computer science?
Teeb meem tus neeg muag khoom mus txawv tebchaws ( TSP ) yog qhov teeb meem analgorithmic ua haujlwm nrog nrhiav txoj hauv kev luv tshaj plaws ntawm cov ntsiab lus thiab qhov chaw uas yuav tsum tau mus xyuas. Kev tsom xam onoptimization, TSP feem ntau yog siv rau hauv computer science txhawm rau nrhiav txoj hauv kev zoo tshaj plaws rau cov ntaub ntawv mus ncig ntawm ntau lub nodes.
Kuj Paub, TSP puas yog NP? Vim li cas TSP Tsis yog NP - Ua tiav Vim nws tsis nyob hauv NP , nws ua tsis tau NP - ua tiav. Hauv TSP koj tab tom nrhiav rau qhov shortestloop uas mus los ntawm txhua lub nroog hauv ib pawg ntawm lub nroog. Txij li nws yuav siv sij hawm exponential los daws NP , cov tshuaj tsis tuaj yeem kuaj xyuas hauv lub sijhawm polynomial. Yog li qhov teeb meem no NP - nyuaj, tab sis tsis nyob rau hauv NP.
Ua raws li qhov xav tau, TSP hauv DAA yog dab tsi?
Teeb meem tus neeg muag khoom mus txawv tebchaws ( TSP ) yog ib qho teeb meem nrov lej uas nug txog qhov ua tau zoo tshaj plaws uas tau muab cov ntsiab lus thiab qhov deb uas yuav tsum tau mus xyuas. Hauv computer science, qhov teeb meem tuaj yeem siv rau lawv txoj hauv kev zoo tshaj plaws rau cov ntaub ntawv mus ncig ntawm ntau cov nodes.
Vim li cas TSP NP ua tiav?
Pov Thawj: Qhia qhov ntawd TSP is NP - Nyuaj , peb yuav tsum qhia tias txhua qhov teeb meem y hauv NP txo rau TSP hauv lub sijhawm polynomial. Txhawm rau ua qhov no, xav txog qhov kev txiav txim siab version ntawm Hamiltonian Cycle (HC). Nws paub zoo tias HC yog NP - Ua kom tiav , li no HC NP - Nyuaj thiab txhua qhov teeb meem y hauv NP txo rau HC hauv polynomialtime.

Ob qhov tseem ceeb ntawm lub voj voog ntawm tes yog dab tsi thiab dab tsi tshwm sim rau lub cell hauv txhua theem?
Muaj ob theem tseem ceeb hauv lub voj voog ntawm tes. Thawj theem yog interphase thaum lub cell loj hlob thiab replicates nws DNA. Qhov thib ob yog theem mitotic (M-Phase) thaum lub sijhawm cell faib thiab hloov ib daim qauv ntawm nws cov DNA mus rau ob lub hlwb zoo tib yam
Cov kauj ruam ntawm mitosis yog dab tsi thiab dab tsi tshwm sim hauv txhua qhov?
Mitosis muaj tsib theem sib txawv: interphase, prophase, metaphase, anaphase thiab telophase. Cov txheej txheem ntawm cell faib tsuas yog ua tiav tom qab cytokinesis, uas tshwm sim thaum lub sij hawm anaphase thiab telophase. Txhua theem ntawm mitosis yog tsim nyog rau cell replication thiab faib
