Izi zidzatipatsa chitsanzo chomwe chimayenda mofulumira pamene chikupangabe zotsatira zomwe zimagwirizana ndi zotsatira za kuyerekezera mwatsatanetsatane.
Tinayamba ntchito yachitukuko ndi zitsanzo zamagulu ang'onoang'ono. Tsopano popeza tili ndi zitsanzo zatsatanetsatane, tikufuna kuwonetsetsa kuti zitsanzo zamtunduwu zimatulutsa zotsatira zofanana.
Chobiriwira chikuwonetsa zofunikira zomwe tidalandira. Tikufuna kuti zotsatira zachitsanzo chosamveka, chosonyezedwa apa mu buluu, kuti zikhale pafupi ndi zotsatira kuchokera ku chitsanzo chatsatanetsatane cha chitsanzo, chosonyezedwa mofiira.
Kuti tichite izi, tidzafotokozera mphamvu zomwe zimagwira ntchito komanso zowonongeka zachitsanzo chosamveka pogwiritsa ntchito chizindikiro cholowetsa. M'malo mogwiritsa ntchito zikhalidwe zosiyana zamphamvu yogwira ntchito komanso yotakataka, tipanga choyimira chokhazikika ndikusintha magawowa kuti ma curve amphamvu komanso osunthika kuchokera pazotsatira zofananira zachitsanzocho zigwirizane ndi mtundu watsatanetsatane.
Kenako, tiwona momwe fanizo losamveka lingasinthidwe kuti lifanane ndi zotsatira zatsatanetsatane watsatanetsatane.
Iyi ndi ntchito yathu. Tili ndi chitsanzo chodziwika bwino cha gawo mu netiweki yamagetsi. Tikayika chizindikiro chowongolera chotere kwa icho, zotsatira zake ndizotsatira zamphamvu yogwira komanso yogwira ntchito.
Tikayika chizindikiro chomwechi pakuyika kwachitsanzo chatsatanetsatane, timapeza zotsatira ngati izi.
Timafunikira zotsatira zofananira zachitsanzo chosamveka komanso chatsatanetsatane kuti chikhale chofanana kuti tithe kugwiritsa ntchito fanizo lachidziwitso kuti tibwereze mwachangu pachitsanzo chadongosolo. Kuti tichite izi, tidzasintha zokha magawo amtundu wa abstract mpaka zotsatira zigwirizane.
Kuti tichite izi, tidzagwiritsa ntchito SDO, yomwe imatha kusintha magawo mpaka zotsatira zamitundu yodziwika bwino komanso yatsatanetsatane igwirizane.
Kuti tikonze zoikamo izi, tidzatsatira njira zotsatirazi.
- Choyamba, timalowetsa zotulutsa zofananira zachitsanzo chatsatanetsatane ndikusankha deta iyi kuti tiyesere.
- Tidzafotokozeranso magawo omwe akuyenera kukhazikitsidwa ndikuyika magawo a parameter.
- Kenaka, tidzayesa magawo, ndi SDO kusintha magawo mpaka zotsatira zigwirizane.
- Pomaliza, titha kugwiritsa ntchito zolowetsa zina kuti titsimikizire zotsatira za kuyerekezera kwa parameter.
Mutha kufulumizitsa kwambiri ntchito yachitukuko pogawa zofananira pogwiritsa ntchito computing yofananira.
Mutha kuyendetsa zofananira pamitundu yosiyanasiyana ya purosesa yamitundu yambiri kapena pamagulu owerengera. Ngati muli ndi ntchito yomwe imafuna kuti muzitha kuyerekezera kangapo - mwachitsanzo, kusanthula kwa Monte Carlo, kuyika magawo, kapena kuyendetsa maulendo angapo apaulendo apaulendo - mutha kugawa zofananirazi poziyendetsa pamakina apakati kapena pagulu la makompyuta.
Nthawi zambiri, izi sizikhala zovuta kuposa kusinthira kwa loop mu script ndi kufanana kwa loop, parfor. Izi zitha kupangitsa kuti pakhale kuthamanga kwambiri pakuthamanga koyerekeza.
Tili ndi chitsanzo cha netiweki yamagetsi ya ndege. Tikufuna kuyesa netiwekiyi m'njira zosiyanasiyana - kuphatikiza maulendo apandege, kusokoneza komanso nyengo. Tidzagwiritsa ntchito PCT kufulumizitsa mayesowa, MATLAB kuti tiyike chitsanzo pamayeso aliwonse omwe tikufuna kuchita. Kenako tidzagawa zofananirazo pamagawo osiyanasiyana apakompyuta yanga. Tiwona kuti mayeso ofananira amamaliza mwachangu kwambiri kuposa otsatizana.
Nazi njira zomwe tifunika kutsatira.
- Choyamba, tidzapanga njira zambiri za ogwira ntchito, kapena otchedwa antchito a MATLAB, pogwiritsa ntchito lamulo la parpool.
- Kenako, tidzapanga ma seti a parameter pamayeso aliwonse omwe tikufuna kuyesa.
- Tidzayendetsa zofananira poyamba motsatizana, chimodzi pambuyo pa chimzake.
- Ndiyeno yerekezerani izi ndi kuthamanga kayeseleledwe mu kufanana.
Malinga ndi zotsatira, nthawi yonse yoyesera mumayendedwe ofanana ndi pafupifupi 4 nthawi zochepa kuposa momwe zimayendera. Tidawona m'magrafu kuti kugwiritsa ntchito mphamvu nthawi zambiri kumakhala pamlingo woyembekezeredwa. Mawonekedwe apamwamba amakhudzana ndi zochitika zosiyanasiyana zapaintaneti pamene ogula amazimitsa ndi kuzimitsa.
Zoyesererazo zidaphatikizanso mayeso ambiri omwe tidatha kuthamanga mwachangu pogawa zofananira pamakompyuta osiyanasiyana. Izi zinatithandiza kuwunika momwe ndege zimayendera.
Tsopano popeza tatsiriza gawo ili lachitukuko, tiwona momwe tingapangire zolemba pa sitepe iliyonse, momwe tingayendetsere mayeso ndikulemba zotsatira.
Kupanga dongosolo nthawi zonse kumakhala kobwerezabwereza. Timapanga kusintha kwa polojekiti, kuyesa kusintha, kuyesa zotsatira, kenaka kupanga kusintha kwatsopano. Njira yolembera zotsatira ndi zifukwa zosinthira zimatenga nthawi yayitali. Mutha kusintha izi pogwiritsa ntchito SLRG.
Pogwiritsa ntchito SLRG, mutha kusintha mayesedwewo ndikutengera zotsatira za mayesowo ngati lipoti. Lipotilo lingaphatikizepo kuwunika kwa zotsatira zoyesa, zithunzi zamitundu ndi ma graph, C ndi MATLAB code.
Ndimaliza ndi kukumbukira mfundo zazikulu za ulalikiwu.
- Tinawona mipata yambiri yosinthira chitsanzocho kuti tipeze kulinganiza pakati pa kukhulupirika kwachitsanzo ndi liwiro la kayeseleledwe—kuphatikiza mitundu yofananira ndi milingo yotengera machitsanzo.
- Tidawona momwe tingafulumizitsire zoyeserera pogwiritsa ntchito ma aligorivimu okhathamiritsa komanso ma computing ofanana.
- Pomaliza, tidawona momwe tingafulumizitsire ntchito zachitukuko pongogwiritsa ntchito zoyeserera ndi zowunikira mu MATLAB.
