Efficiency ntawm ib qho algorithm txhais tau tias sai npaum li cas nws tuaj yeem tsim qhov tseeb rau qhov teeb meem muab. Cov efficiency ntawm ib algorithm nyob ntawm nws lub sij hawm complexity thiab spacecomplexity. complexity ntawm ib algorithm yog ib txoj haujlwm uas muab lub sijhawm khiav thiab qhov chaw rau cov ntaub ntawv, nyob ntawm seb qhov loj npaum li cas los ntawm peb.

Yog li ntawd, dab tsi yog algorithm thiab nws efficiency?

algorithm efficiency Ib qho kev ntsuas ntawm tus nruab nrab execution lub sij hawm tsim nyog rau ib tug algorithm ua kom tiav kev ua haujlwm ntawm ib txheej ntawm cov ntaub ntawv. Algorithm efficiency ischaracterized los ntawm nws xaj. Feem ntau yog npuas hom algorithm yuav muaj efficiency nyob rau hauv sorting N khoomproportional rau thiab ntawm tus xaj n 2, feem ntau sau O(N 2).

Ib sab saum toj, dab tsi yog ob qho kev ntsuas tseem ceeb rau kev ua haujlwm ntawm ib qho algorithm? Algorithm Efficiency Feem ntau muaj tej yam ntuj tso units rau lub domain andrange ntawm no muaj nuj nqi. Muaj ob lub ntsiab nyuaj ntsuas ntawm efficiency ntawm ib tug algorithm : Timecomplexity yog ib txoj haujlwm piav qhia txog lub sijhawm algorithm yuav siv sij hawm nyob rau hauv cov nqe lus ntawm tus nqi ntawm input mus rau lub algorithm.

Kuj nug, peb tuaj yeem ntsuas qhov ua tau zoo ntawm cov algorithm li cas?

Algorithm Efficiency

  1. Lub sij hawm efficiency - ib qho kev ntsuas ntawm lub sij hawm rau ib tug algorithmto ua.
  2. Qhov chaw efficiency - ib qho kev ntsuas ntawm tus nqi ntawm lub cim xeeb xav tau rau lub algorithm los ua.
  3. Complexity txoj kev xav - kev kawm ntawm kev ua tau zoo algorithm.
  4. Function dominance - kev sib piv ntawm cov nqi zog.

Qhov programming efficiency yog dab tsi?

Code efficiency yog ib lo lus dav siv los piav txog kev ntseeg siab, ceev thiab programming methodology siv indeveloping codes rau ib daim ntawv thov. Code efficiency yog ncaj qha txuas nrog algorithmic efficiency thiab ceev ntawmruntime ua rau software. Nws yog lub hauv paus tseem ceeb hauv kev ua kom muaj kev ua haujlwm siab.
