Indlela ukuba bahlanganise i Rubik kaThixo Cube 2x2. Algorithm ibandla Rubik kaThixo Cube 2x2

Rubik kaThixo Cube - ukuba omnye ethandwa kakhulu futhi kuthandwa ngabantu abaninzi puzzle.

A bit of amanqaku ngembali

Toy ebizwa "Cube Rubik kaThixo" lwasungulwa 1974 ngu nomkroli Hungarian njingalwazi izakhiwo Erno Rubik. Kukho kwinguqulo ekuqaleni le puzzle yaphuhliswa njengesixhobo lemfundo apho abantwana kuba lula ukuqonda ingcamango iqela zemathematika.
Ekuqaleni izilingo 27 ityhubhu yamaplanga kunye imida imibala eyahlukileyo. Kamva, ngaphezu kwakanye zatshintsha de ufumene ifomu yayo yokugqibela. Kwaye kakade ngo-1975, umbhekisi phambili wesi yokudlala laqala lomenzi fyabo, emva koko cube-Rubik (ngoko bawabize efanayo) waya imveliso mass. Yena kuqala baya kwintengiso njengoko yokudlala Unyaka Omtsha ngo-1978 phantsi kwegama "Magic Cube"
Emva koko kwakukho ukunyuka okukhulu ukuthandwa puzzle, kwaye ukuhla kwemfuno phakathi abathengi. Kwaye ngexesha lethu, umdla cube ye Rubik baqalisa kwakhona ukukhula ngenkuthalo.

Ukuqhuba lonke Rubik cube 2x2

Ngokuthenga le puzzle, abaninzi bachithe iintsuku okanye iiveki ukuba iphazili ngaphezulu, ukuqokelela njani. Yaye yonke kuphumelela. Ukuze ufunde ukuqokelela indlela Rubik kaThixo Cube 2x2, akazekeleli ukuba yingqondi. Kwanele ukuhlola kwizikim esele kanye ubuchule ezizodwa, apho ungenza ngokukhawuleza nangokulula bahlanganisane kuyo. Kuba ibandla ecacileyo Rubik kaThixo Cube 2x2 yemizobo kuya kukunceda ngokulula ukumelana nendlela yokwenza oko.

Namhlanje ezivenkileni uyakwazi ukufumana iintlobo ezahlukeneyo abanokukhetha kuzo Cube the Rubik esithi: Cube kunye iiseli 2 ngomhla we-2, 3 3, 4 4, 5 5, njalo njalo Makhe bemiyo phezu ulwazi iluncedo kwabasaqalayo Kubera ezizezi .. indlela bahlanganise i Rubik kaThixo cube 2x2. Kukho algorithm ethile le ndibano puzzle, ngaphandle ulwazi ongayi kuba elide kakhulu yaye ngokungeyompumelelo ezama ukuyisombulula ngayo. Kubalulekile ukuqaphela ukuba inani elikhulu labantu ehlabathini lonke kwakhiwe Cube a Rubik yaba mxholo wokhuphiswano. Ngokomzekelo, omnye cuber baqeqeshwe kakuhle ukuqokelela cube Rubik, imizuzwana mathathu, ngelixa ntshatsheli - ubuninzi ezisibhozo. Ukuze ufumane kufutshane kancinci ukuya iziphumo ezinjalo, cinga iinketho ukuba bahlanganisane indlela Rubik kaThixo Cube 2x2. Le yokudlala i mini-uguqulelo iqulathe imibala ezintandathu macala ezintandathu, nganye eneyazo idayisi ezine. Le cube akukho lula ukuba phinda njengoko kusenokubonakala xa efika kuqala. Nokuba kukho inani elincinane lwendibaniso kuthelekiswa ngomgangatho 3x3 Cube Rubik kaThixo, lo mfundi Kubera kufuneka achithe ixesha elininzi ukwakha 2x2 ngempumelelo Cube Rubik baba yokwenene.

Driving 2x2 ibandla Rubik

Cube ibandla Driving sokuLwa Rubik kaThixo (ngamanye amaxesha ibizwa ngokuba 2x2 cube-Rubik) kuyinto snap. Emva eli cebo, kunokwenzeka ukuba bahlanganise i Rubik kaThixo Cube 2x2 ubuninzi lemizuzu engama-20. Ngaphambi kokuqhubeka ngqo inkqubo ibandla, kuyimfuneko ukufunda incwadi maphupha, kwaye imiqathango ezichazwe kulo.

lwesigama

Xa inkcazo cube scheme ibandla Rubik, kunokwenzeka ngokuqhelekileyo ukufumana isigama ekhethekileyo osetyenziswayo ukubonisa ulandelelwano moya uzijukelezo ityhubhu.

Okokuqala yaye okubaluleke kakhulu, oko kufuneka uqonde - iisimboli zamaqela (iinqwelomoya) cube. Ukuze wenze oku, thatha le 2x2 cube-Rubik esandleni ukuze enye moya yalo kumgangatho wamehlo. Yiyo le icala ibizwa ngokuba phambi idayisi, kwaye luchazwa yileta F (F). Elinye icala alathelwe ngolu hlobo lulandelayo:
• H (D) - yasezantsi;
• B (U) nguye ephezulu,
• P (R) - ekunene,
• L (L) - ekhohlo,
• T (B) - angasemva.
Kulo mzekelo, umbala macala cube awungeni ndawo.

Indlela ukuba bahlanganise amagaqa 2x2 Rubik kaThixo, elandela le nkqubo?

Yinto elula kakhulu - kubalulekile ukuba balandele ngqo le emacaleni indawo cube ekhethiweyo ekuqaleni indibanisela.
Kunye nokuzimisela kunye nolwabiwo iinqwelomoya cube kubonakala uku bana phandle ukuzenza ngazo ngoku? Kukho iindidi ezimbini kumadayisi ejika moya: lokuqala - ukuvula 90 ° ngku kunye yesibini - 90 ° kwicala elahlukileyo - ebalwa.
Kukho imiqondiso emininzi esetyenziswayo kwinkqubo ibandla, cube Rubik:
• uphawu " '" - osetyenziswa ukujikeleza kwi kwicala langasekunene malunga kubonisiwe ngaphambili ecaleni;
• Kungenzeka kwakhona ukusebenzisa nobhalo "2", into ethetha ukuba icala izidanga kabini-turn 90 (ewonke - 180 degrees).
Ngoko ke, cinga 2x2 ibandla cube algorithm Rubik kaThixo.

Inyathelo № 1. Ukubeka umaleko wokuqala (ngaphantsi)

Into yokuqala ukuyenza - aqokelele umaleko ephantsi ukuze bonke abane dice ezantsi baba umbala omnye, yaye imidlalo ezimbini ezishiyekileyo iityhubhu umbala ibekwe ebumelwaneni. Emva kwendibano, umaleko okungenzimanga dlulelani kwinyathelo elilandelayo ikuvumela ukuba uqonde indlela yokwenza a Rubik kaThixo Cube 2x2 (okanye mandithi, ukuqokelela kuyo).

Inyathelo № 2. Ukubeka dice topsheet

Kweli nqanaba, indibano kufuneka zibekwe iibhloko, ibekwe indawo yayo ephezulu, endaweni yayo, akukho mfuneko yokuba utshatise imibala zabo. Le yokugqibela kungenziwa kamva.

Okokuqala, kufuneka amisele umbala moya eliphezulu. Yenza ita ilula: umbala kumphezulu eliphezulu cube - umbala, apho akakho kule nwebu asezantsi. Ngaphezu koko kuyimfuneko ukuzitshintsha inxalenye ephezulu de cube okhethiweyo akanalo akuthathi indawo ephezulu, betha engile yonqumlo zontathu imibala i element. Kulo mzekelo, akukho mfuneko kweli nqanaba i element ekhethiweyo utshatise imibala.

Emva enye ezimbombeni zone cube Iqinisekile, kuyimfuneko ukuba endaweni ngokuchanekileyo inxalenye saso ezimbombeni zaso eseleyo. Oku kunokwenziwa ngokukhetha enye imixube ezimbini ekhoyo. Indibaniselwano lokuqala ikuvumela ukuba ukutshintsha iibhloko oxwesileyo, owesibini - okufuphi. Ngenxa yoko, ukuze lokubeka ngokuchanekileyo zonke iityhubhu yembombo, kufuneka kuphela khetha indibaniselwano ekunene. Oku kudityaniswa ngolu hlobo lulandelayo: VFPVP'V'F '(1) FVF'V'L'V'L (2).

Action № 3. Jikelezisa iityhubhu topsheet

Zonke imixube eyenziwe ngeli nqanaba indibano Cube the Rubik kaThixo, kufuneka nesithandwa sakhe. Ekuqaleni, omnye umele uvule angle (umz, ebalwa), ngoko ke wesibini, kodwa kwelinye icala ngokungqinelana indibanisela yesibini (ngku). La manyathelo efanayo zingenziwa iimbombo amathathu ukuba kufuneka babuyele kwicala efanayo (kulo mzekelo izihlandlo ezithathu, enye yezi ezihamba).

Kweli nqanaba, kusenokubonakala ngathi ukuba cube kuye kwayinto ezinobunzima ifomu, kodwa musa ukukhathazeka. Ukuze ukubuyela kwakhona imboniselo ityhubhu ndawonye, kuyimfuneko ukutshintsha imo yekona eyahlukileyo kwelinye icala nje ukuba nje oku akwenzeki. Ngelo xesha phakathi lwemisebenzi eqhubekayo, jikeleza nje ubuso phezulu logama nje engile ethile iya kuba kwikona ephezulu ngasekunene. Kolimo: P'N2PFN2F '(3) FN2F'P'N2P (4).
Kuba zintathu ekufuneka ajikeleziswe kwicala elinye, ungasebenzisa kwakhona ezinye iindlela ezihamba kunye. Umzekelo, a cube nga ibekwe ukuze engile ekhethiweyo ubuyeleyo kude ephezulu ekhohlo.

Ukwenza ithuba lwezinye ezimbombeni ezintathu kwelinye icala ukuya kwicala langasekunene, ngokusebenzisa imixube zilandelayo: (VFPVP'V'F ') 2 (5) - intlanganisela (1) wenza kabini; V2FV2F'V'FV'F 'okanye (6); okanye FVF2LFL2VLV2 (7);
Ukujikeleza kwinkalo enye, kodwa kufuneka wenziwe kwicala langasekunene ngokwenza intlanganisela enjalo: (FVPV'P'F'V ') 2 (8) - intlanganisela (2) eyenziwa kabini; FVF'VFV2F'V2 okanye (9); okanye V2L'V'L2F'L'F2V'F '(10).

Enyanisweni, Cube ibandla 2x2 Rubik kunokuba yinto elula kwaye fun. Eyona nto ibalulekileyo kukuba ukuba balandele ngqo le algorithm echazwe ngentla-yezenzo, kwaye ke konke kuya kuphumelela. Kwaye ke ungavele ukuthatha iiphazili ezinobunzima!
