Chav Kawm: Nrhiav algorithm
Yog li ntawd, dab tsi yog qhov piv txwv ntawm kev tshawb nrhiav linear?
Kev Tshawb Fawb . Ib qho yooj yim tshaj plaws thiab theem pib tshawb nrhiav yog cov kev tshawb nrhiav , kuj hu ua a linear nrhiav . Raws li lub ntiaj teb tiag piv txwv , khaws phau ntawv xov tooj ze tshaj plaws thiab qhib rau thawj nplooj ntawv npe. Peb tab tom nrhiav nrhiav thawj "Smith".
Ib tug kuj yuav nug, dab tsi yog txhais los ntawm linear search? Kev tshawb nrhiav kab , kuj hu ua kev tshawb nrhiav , yog tus txheej txheem uas kuaj xyuas txhua lub ntsiab lus hauv daim ntawv teev npe ua ntu zus kom txog thaum pom cov khoom xav tau. Computational complexity rau linear nrhiav yog O(n), ua rau nws feem ntau tsawg npaum li cas binary nrhiav (O(log n)).
Ntawm no, qhov txawv ntawm linear search thiab binary search yog dab tsi?
A linear nrhiav scans ib yam khoom ntawm ib lub sij hawm, tsis txhob dhia mus rau ib yam khoom. Piv txwv li, binary nrhiav txiav koj nrhiav mus rau ib nrab kom sai li sai tau thaum koj pom qhov nruab nrab ntawm ib daim ntawv teev npe. Hauv linear nrhiav , qhov teeb meem nyuaj tshaj plaws yog O (n), qhov twg binary nrhiav ua O(log n) sib piv. Kev tshawb nrhiav kab siv ua ntu zus mus kom ze.
Dab tsi yog qhov nyuaj ntawm kev tshawb nrhiav linear?
Kev tshawb nrhiav kab
| Chav kawm | Nrhiav algorithm |
|---|---|
| Kev ua tau zoo tshaj plaws | O(n) |
| Kev ua haujlwm zoo tshaj plaws | O(1) |
| Nruab nrab kev ua tau zoo | O(n) |
| Qhov phem tshaj qhov chaw complexity | O(1) rov |

Dab tsi yog cov tshuab tshawb nrhiav uas tshawb nrhiav lwm lub tshuab tshawb fawb?
Txhawm rau pib tawm ntawm peb txoj kev tshawb nrhiav taug txuj kev nyuaj, cia saib qee qhov kev tshawb fawb dav dav tshaj qhov peb sab saum toj. DuckDuckGo. Kev txhawj xeeb txog kev ceev ntiag tug hauv online? Nrhiav Encrypt. Nrhiav rau lwm txoj rau DuckDuckGo? Ecosia. Xav tau tsob ntoo cog thaum koj tshawb nrhiav? Dogpile. Blekko. WolframAlpha. Gigablast. Facebook Nrhiav
Dab tsi yog qhov dav thawj qhov kev tshawb nrhiav thiab qhov tob thawj qhov kev tshawb fawb?
BFS sawv rau Breadth First Search. DFS sawv cev rau Kev Tshawb Nrhiav Qhov tob. 2. BFS (Breadth First Search) siv Queue cov qauv ntaub ntawv los nrhiav txoj hauv kev luv tshaj. BFS tuaj yeem siv los nrhiav ib qhov chaw luv tshaj plaws hauv cov duab tsis hnyav, vim tias hauv BFS, peb mus txog qhov kawg uas muaj qhov tsawg kawg nkaus ntawm cov npoo los ntawm qhov chaw vertex
Dab tsi yog qhov txawv ntawm kev sib raug zoo unary kev sib raug zoo binary thiab kev sib raug zoo ternary?
Kev sib raug zoo tsis sib xws yog thaum ob tus neeg koom hauv kev sib raug zoo yog tib lub koom haum. Piv txwv li: Cov ncauj lus yuav yog qhov yuav tsum tau ua ua ntej rau lwm yam kev kawm. Kev sib raug zoo ternary yog thaum peb lub koom haum koom nrog kev sib raug zoo
Dab tsi yog qhov zoo ntawm kev tshawb fawb zoo tshaj li kev tshawb fawb ntau?
Cov ntaub ntawv los ntawm kev tshawb fawb ntau - xws li kev lag luam loj, pej xeem, thiab cov neeg siv nyiam - muab cov ntaub ntawv tseem ceeb rau kev txiav txim siab ua lag luam. Kev tshawb fawb zoo muab cov ntaub ntawv tseem ceeb rau kev siv hauv kev tsim cov khoom lag luam-nrog rau cov ntaub ntawv hais txog cov neeg siv khoom xav tau, tus qauv coj tus cwj pwm, thiab cov ntaub ntawv siv
Dab tsi yog qhov sib txawv tseem ceeb ntawm kev sib txuas lus tsis sib xws thiab kev sib txuas lus taw qhia?
1. Hauv kev sib txuas lus tsis muaj kev sib txuas lus tsis tas yuav tsim kev sib txuas ntawm qhov chaw (sender) thiab qhov chaw (receiver). Tab sis nyob rau hauv kev sib txuas-taw qhia kev sib txuas lus kev sib txuas lus yuav tsum tau tsim ua ntej hloov cov ntaub ntawv
