<prompt> Fingqa isihloko: Kudinga ukuprakthiza ukuze ube nekhono lokushanela amakhadi ngendlela esheshayo nenhle. Kodwa isazi sezibalo siye saphawula ukuthi ukugibela ngezindiza okwenziwa ngamakhadi akuqinisekisi ukuthi kuyoba neqoqo lezinhlamvu elihlelwe ngendlela engahleliwe. I-Peri Diaconis yaqhathanisa amasu ahlukahlukene okuxuba futhi kubonakala sengathi i-riffle shuffle, okuhilela ukusika idokodo libe yizicucu bese uxuba izingxenye zibe yizicucu, iyona esebenza kahle kakhulu - uma yenziwe kahle. Skrolela phansi ukuze ubone ividiyo. UPeri Diaconis waqhathanisa amasu ahlukahlukene okuxuba futhi wathi ukuxuba ukuhlanekezela okufanekiselwe, okuhilela ukusika idokodo phakathi bese uxuba izingxenye komunye nomunye, kuyindlela ephumelela kakhulu futhi engahleliwe uma yenziwe kahle. Kwi-video ye-YouTube ye-Numberphile, isazi sezibalo saseStanford University sathi uma umthengisi esebenzisa i-riffle shuffle, kudingeka aphinde inqubo izikhathi eziyisikhombisa kuphela ukuze athole inhlanganisela enhle. Uma benekhono lokudlala amakhadi, lokhu kungathatha imizuzwana engaphansi kwengu - 30. Kodwa uma besebenzisa i - overhand shuffle, okuhilela ukufaka ngokushesha izingcezu zamakhadi ezivela esandleni esisodwa zibe ingxenye enkulu yamakhadi aphethwe kwesinye, kuyodingeka bakwenze izikhathi ezingu - 10 000 ukuze bathole imiphumela efanayo. Lokhu kusengashesha ezandleni zochwepheshe, kodwa kusehamba kancane kunendlela ye-rifle. Kukhona indlela yesithathu yokuxuba amakhadi - esetshenziswa emincintiswaneni ye-poker naseMonte Carlo - engiyibiza ngokuthi yi-smooshing, kusho uDkt Diaconis. Kwi-video ye-Numberphile, uDkt Diaconis waqhathanisa izitayela zokuxuba ukuze achaze ukusebenza kwazo okufanekisiwe Uma umthengisi esebenzisa ukuxuba okuphezulu okufanekisiwe, okubandakanya ukufaka ngokushesha izingcezu zamakhadi ezingahleliwe ezivela esandleni esisodwa kuningi lamakhadi aphethwe kwesinye, kuzodingeka bakwenze izikhathi eziyi-10,000 ukufeza imiphumela efanayo ne-riffle shuffle. INDLELA YESIFOFELO. Inqubo: Ukusika iphakethe lamakhadi phakathi bese uwaxuba ngokushesha. Ukusebenza kahle: Umdayisi udinga ukuphinda inqubo izikhathi eziyisikhombisa ukuze akhulule iphakethe futhi lokhu kungenziwa ngemizuzwana engaphansi kwengu-30. INDLELA YOKUPHATHEKA. Inqubo: Ukufaka ngokushesha izingcezu zamakhadi...  <response>: Isazi sezibalo saseNyuvesi yaseStanford saqhathanisa izindlela zokuxuba. Abadayisi abasebenzisa i-riffle shuffle kudingeka baphinde inqubo izikhathi eziyisikhombisa ukuze bathole iphakethe lamakhadi elizenzakalelayo, kusho uPeri Diaconis. Le nqubo ihilela ukusika i-deck nokuxuba izingxenye ndawonye. Nakuba i-overhandkudingeka iphindwe izikhathi ezingu-10 000 ukuze ithole imiphumela efanayo. Indlelayokushanelanoma yokuwasha ithatha umzuzu owodwa ukukhetha amakhadi ngokungahleliwe.
