7 Cov kauj ruam los daws qhov teeb meem Dynamic Programming

  1. Yuav ua li cas paub txog qhov teeb meem DP.
  2. Txheeb xyuas qhov teeb meem sib txawv.
  3. Qhia meej txog kev sib raug zoo dua.
  4. Txheeb xyuas cov xwm txheej hauv paus.
  5. Txiav txim siab yog tias koj xav siv nws rov ua dua lossis rov ua dua.
  6. Ntxiv memoization.
  7. Txiav txim siab lub sijhawm nyuaj.

Ib yam li ntawd, koj tuaj yeem nug, qhov twg yog qhov programming dynamic siv?

Dynamic programming yog siv qhov twg peb muaj teeb meem, uas tuaj yeem muab faib ua cov teeb meem zoo sib xws, kom lawv cov txiaj ntsig tuaj yeem rov ua dua. siv . Feem ntau, cov algorithms no yog siv rau optimization. Ua ntej daws qhov teeb meem hauv tes, dynamic algorithm yuav sim tshuaj xyuas cov txiaj ntsig ntawm cov teeb meem yav dhau los daws teeb meem.

Ib tug kuj yuav nug, dab tsi yog dynamic programming piv txwv? Piv txwv : Knapsack. Piv txwv : Matrix-chain multiplication. Dynamic Programming yog cov txheej txheem muaj zog uas tuaj yeem siv los daws ntau yam teeb meem hauv lub sijhawm O (n2) lossis O (n3) uas txoj hauv kev tsis ncaj ncees yuav siv sij hawm exponential.

Tsis tas li ntawd, muaj pes tsawg txoj hauv kev koj tuaj yeem siv dynamic programming?

Muaj ob txoj kev mus kom ze txhua qhov programming dynamic raws teeb meem.

Puas yog dynamic programming siv hauv lub neej tiag tiag?

Dynamic programming yog hnyav heev siv hauv computer networks, routing, teeb meem teeb meem, computer vision, artificial txawj ntse, machine learning thiab lwm yam. Nws nyob qhov twg siv hauv lub neej tiag tiag ? Txhawm rau qhia cov dynamic - programming txoj kev daws teeb meem lub neej tiag teeb meem, cia peb xav txog ib qho teeb meem raws li kev khiav tsheb.
