Isibali sokuphinda-phinda
Ukuphinda-phinda kwahlula iinxalenye zakho zibe ziindidi zonke ezincinci zokuphinda-phinda ngobukhulu obukhethayo. Ngeenxalenye ezi-4 kunye nokuphinda-phinda kweenxalenye ezi-2, kukho 6 ukuphinda-phinda; ngeenxalenye ezi-6 kunye nokuphinda-phinda kweenxalenye ezi-3, 20. Faka amathuba aseMelika okanye amathuba e-desimali kunye nesiphumo ngasinye.

Indlela esebenza ngayo
- Inani lokuphinda-phinda = inani leendlela zokukhetha iinxalenye eziyi-k kwiinxalenye eziyi-n: C(n, k). Umngcipheko opheleleyo = elo nani × isabelo ngokuphinda-phinda ngakunye.
- Ukuphinda-phinda ngakunye kuhlawula imveliso yamathuba e-desimali eenxalenye zawo ukuba zonke iinxalenye ziyaphumelela; ukulingana kubalwa njengamathuba ali-1, ukuphulukana kuthoba kuphela oko kuphinda-phinda.
- I-round robin isasaza umngcipheko kwiinkqubo ezininzi zokuphinda-phinda ezincinci, kodwa inxalenye nganye isaphatha umkhono wombhuki, kwaye ukuphinda-phinda ngakunye kuphinda-phinda lo mkhono: bona into ekwaziyo ukuphinda-phinda.
