Model Xisaabeed: marxaladaha of design

Tan iyo bartamihii qarnigii la soo dhaafay ee beeraha kala duwan ee dhaqdhaqaaqa aadanaha bilaabay inuu ka computer iyo hababka xisaabta. Markaasay waxay bilaabeen inay u muuqdaan nidaamo cusub sida dhaqaalaha xisaabta, cilmi afaf xisaabta, kimisteriga xisaabta, iyo kuwa kale, kuwaas oo daraasaad ku dayashada xisaabeed ee ifafaale iyo walxaha, iyo sidoo kale hababka ay waxbarasho.

model Xisaabeed - waa tilmaan qiyaas ah ee walxaha luqad xisaabeed ama ifafaale ee dunida dhabta ah. Ujeedada ugu weyn ee mataalada qabata walxaha macluumaadka cilmi baadhista iyo saadaaliyo natiijada indhaynta mustaqbalka. Intaa waxaa dheer, Tusaale waa hab iyo aqoonta ilaalinta deegaanka, dunida taas oo ka dhigaysa waxaa suurto gal ah in la xakameeyo.

Isticmaalka Qaabaynta xisaabta waa lagama maarmaan in kiisaska sababo kala duwan waa ay adag tahay ama aan macquul aheyn in ay soo saaraan tijaabo dabiiciga ah. Tusaale ahaan, waa ay adag tahay si aad u hubiso haddii ay run tahay ama aragti in cosmological waa, ama si ay u sahamiyaan cawaaqibka of qarax nuclear. Laakiin oo dhan of this waxaa laga arki karaa on computer ah, pre-dhismaha model xisaabeed.

model Xisaabeed: marxaladaha of design

Waa midda koowaade, dhismaha model ah soo saaray. Si arrintan loo sameeyo, ka fiirso arrin dabiici ah, qorshe dhaqaale, design, habka wax soo saarka ama shay kale oo aan xisaabta. First ogaado sifooyinka iyo ifafaale isgaadhsiinta therebetween heer tayo. Ka dibna, ku tiirsanaanta helay waxaa loo wareejiyey view formula ama model xisaabta. tallaabo Tani waa ugu adag.

In talaabada labaad waxaa loo sameeyaa xalinta dhibaato xisaabeed loo habayn ku saleysan model ah. Halkan, dareenka korodhay horumarinta hababka tiro iyo algorithms lagu xallinayo dhibaatada iyadoo la kaashanayo of computer ah, in aad u ogolaan in waqtiga loo ogol yahay, natiijada si sax ah loo baahan yahay.

Tallaabada xigta waa fasiraadda ka timi cawaaqibka model ah, natiijada turjumaad af xisaabeed ee foomka qaatay aagga daraasadda.

Markaas, xaqiijinta of filaanshaha of model ka helay, aad u ogaato haddii natiijooyinka dhigmaan cawaaqib gudahood sax ah loo dejiyay.

At bedelidii wareega ugu dambeeya ee model ah. Waxaa ama waxa ay dhibaato badan ku filaanshaha ansaxnimada ama ay u fududaato in ay gaaraan xal la aqbali karo wax ku ool ah.

Qoondaynta oo ah moodooyinka xisaabeed

Waxaa jira xeerar kala duwan oo loogu talagalay kala qeybinta lagu daydo xisaabeed ee kooxda. Sidaas darteed, nooca dhibaatooyinka laga hadlayo horyaalka heerka wax soo saarka galay model dhismaha iyo functional. Marka ay tani ifafaale ama shay sifeeyay tiro yihiin tiro ka muujiyay.

model xisaabeed Dhismayaasha waxaa wakiil sida nidaamka ah noocyada kala duwan ee isla'egyada (aljabrada, kala duwan), taas oo adkayn dhexeeya doorsoomayaasha bartay xidhiidhada taranta. Marka tan la eego sida doorsoomayaal sida doorsoomayaal madax bannaan, iyo hawlaha ka soo jeeda, kuwaas oo.

daydo Functional tilmaami shay adag oo ka kooban xubno ka shaqsi dhowr, oo u dhexeeya qaar ka mid ah kuwaas oo xiriir. Sida caadiga ah xidhiidhka xogta waa adag ama aan la tiradeeda. Waayo, waxbarasho la adeegsanayo aragtida ah ee garaafyada of walxaha xisaabeed u taagan set oo ah dhibcood ee meel ama diyaarad.

By dabiiciga ah ee natiijooyinka saadaalinta iyo model xogta asalka ah waxaa loo qaybiyaa probabilistic ma guurto ah iyo deterministic. Nooca ugu horeeya waxa lagu saleeyay xogta tirakoobka la ururiyey, la heli saadaasha kuwanu waa probabilistic.

Waayo, tusaalayaal lagu daydo xisaabeed ayaa loo saarin karaa in dhibaatada of diyaarad laga gano ah, gaadiid, iyo hawlo kale.
