# Isicwangciso esiphumeleleyo sokuwina xa uqikelela amanani0417

UThomas M. Cover wabuza lo mbuzo ulandelayo omangalisayo ngo-1987 ku "Vula Iingxaki Kwezonxibelelwano Nokubala": Umdlali $$X$$ ubhala amanani amabini ahlukeneyo kunye nalawo akhethwe ngokungakhethiyo $$A$$ kunye $$B$$ kwimibini emibini eyahlukeneyo Ingcezu yephepha wayibeka phantsi etafileni. Umdlali $$Y$$ ngoku ukhetha ngokungacwangciswanga elinye lala maqhekeza ephepheni, alibone inani kwaye ngoku kufuneka athathe isigqibo sokuba ingaba eli nani lincinci okanye likhulu kunelinye inani elifihliweyo etafileni.

Umdlali $$Y$$ akanokujika ikhadi elijonge ezantsi. Kuqala ukuvumela ukuba uthathe isigqibo sengqekembe kwaye unesicwangciso esiphumeleleyo sepesenti $$50\%$$ ifunyenwe. Ngaba sikhona esinye isicwangciso esinokubakho okuphezulu?

Phambi kokuba umdlali $$Y$$ akhethe ngokungakhethiyo kula maphepha mabini, umisela inani lendalo elingenakuphikiswa $$C$$ . Emva koko ujika elinye kula maphepha mabini ngokungacwangciswanga. Ngoku uthatha isigqibo ngolu hlobo lulandelayo: Ukuba inombolo eguqulweyo $$\leq C$$ , ukhetha inani elikwelinye uluhlu njengelona likhulu; ukuba inani eliguqulweyo ngu $$> C$$ , ukhetha inani elisandula ukuguqulwa njengowona mkhulu. Ngelishwa, ithuba lokuphumelela ngoku $$> 50\%$$ .

Siqala ukuseta ukutyunjwa kwamanani amabini ku $$A < B$$ . Ke ngoku elinye lamatyala amathathu alandelayo lenzeka kwangoko emva kokukhethwa kwe $$C$$:

• Ityala lokuqala: $$C \leq A < B$$ : Ke amathuba okuphumelela ngu $$50\%$$ , kuba akukho lwazi malunga $$A$$ kunye $$B$$ .
• Ityala lesi-2: $$A < B \leq C$$ : Ke amathuba okuphumelela ngu $$50\%$$ , kuba akukho lwazi malunga $$A$$ kunye $$B$$ .
• Ityala lesithathu: $$A < C < B$$ : Ke amathuba okuphumelela ngu $$100\%$$ , kuba ukuba $$B$$ ijikwe kuqala, umntu uhlala no $$B$$ kwaye ukuba $$A$$ ijikwe kuqala, utshintshela ku $$B$$ , ke uhlala ukhetha inani elikhulu.

Okumangalisayo kukuba, esi sicwangciso sikwasetyenziswa kubomi bemihla ngemihla: Umzekelo, ukuba kuya kufuneka uthathe isigqibo kwangoko okanye ngokuchasene nokuthenga imveliso ngaphandle kokufumana isithembiso sokuthelekisa, uzibekela umda wemali kwangaphambili. Ukuba lo mda wexabiso lokwenyani ufezekisiwe, kuthengiwe kwenziwa-kungenjalo akunjalo.
