Inombolo Yonkulunkulu ku-Magic Cube
Sanibonani nonke, namuhla sizokhuluma ngenani lonkulunkulu ku- I-Magic Cube:
I-Magic Cube iyiphazili ethandwayo Ithoyizi lokho bekulokhu kuthandwa kusukela ngawo-1980. Ngaphambilini, sikhulume ngohlelo lombala olujwayelekile lwe-Magic Cube kanye nokuhlanganiswa kwamaqembu e-Magic Cube. Sifunde ukuthi ukubuyisela i-Magic Cube kuyikhono elidinga abadlali ukuthi bafunde amakhono afanele okudlala ukuze bayibuyisele.
Kodwa-ke, isikhathi esidingekayo ukubuyisela i-Magic Cube siyahlukahluka phakathi kwama-Magic Cubes ahlukene. Abanye abangani bangabuyisela i-Magic Cube ngesikhathi esifushane, okusho ukuthi uma nje bekwazi kahle amasu okubuyisela, inani lokujikeleza elidingekayo ukubuyisela i-Magic Cube lingancishiswa.
Kukangaki sidinga ukujikeleza ukuze sibuyisele i-Magic Cube? Lo mbuzo wenze abathandi be-Magic Cube abaningi bazibuza kusukela ekuqaleni, futhi waze wakhanga isithakazelo sabanye ososayensi bezibalo, ngoba kuyinkinga enzima kakhulu yezibalo. Izazi zezibalo zaze zanikeza leli nani elincane lokujikeleza igama elikhulu, elibizwa ngokuthi "iNombolo KaNkulunkulu."
Kusukela ngawo-1990, izazi zezibalo bezilokhu zifuna leli "nani lonkulunkulu" eliyimfihlakalo. Indlela eqondile kakhulu yokuthola "inani lonkulunkulu" ukubala inani elincane lokujikeleza kwenhlanganisela ngayinye yombala, futhi enkulu ngokusobala inani elincane lokujikeleza elingaqinisekisa ukuthi noma yikuphi ukuhlanganiswa kombala kuyabuyiselwa, okungukuthi, "inani lonkulunkulu". Ngeshwa, izibalo ezinjalo azikwazi ngisho nokwenziwa yikhompyutha, njengoba kunezinhlanganisela eziningi kakhulu zemibala ku-Magic Cube.
Kuze kube ngu-1992, isazi sezibalo saseJalimane okuthiwa uKosenba saphakamisa indlela entsha enezinyathelo ezimbili. Iwukuqala ngokuguqula noma yimuphi umbala ube yinhlanganisela yemibala ekhethekile ekhethwe nguye ngezindlela zezibalo, bese uyibuyisela. Inzuzo yalokhu ukuthi izindleko zokubala zesinyathelo ngasinye zincane kakhulu kunokubala ngokuqondile inani lonkulunkulu.
Kusetshenziswa le ndlela entsha, kwafakazelwa ngo-2007 ukuthi inani lonkulunkulu alikwazi ukudlula u-26. Lokhu kusho ukuthi ngokujikeleza okungu-26 kuphela, noma iyiphi inhlanganisela yombala we-Magic Cube ingabuyiselwa. Kodwa leli nani alikabi "inani lonkulunkulu". Nakuba indlela entsha kaCosimba yehlisa ukubalwa kwezinombolo ezimbili, indlela yokubuyisela etholakele kungenzeka ingabi nenani elincane kakhulu lokujikeleza.
Ngo-2008, uchwepheshe wekhompyutha uRocky wasebenzisa isivumelwano ukuze anciphise isilinganiso sakhe senani lonkulunkulu sibe ngu-22. Kodwa inombolo engu-22 ayisona "inani lonkulunkulu", futhi uphawu olusobala lwalokhu ukuthi abantu abakaze bathole ukuthi noma yikuphi ukuhlanganiswa kombala kudinga ukujikeleziswa okungaphezu kuka-20 ukuze kubuyiselwe, okuholela abantu ekuqageleni ukuthi "inani lonkulunkulu" kufanele libe ngu-20. NgoJulayi 2010, lokhu kuqagela kwagcina kufakazelwe nguCosimba ngokwakhe kanye nabalingani bakhe abaningana.
