Báo cáo toán học: "Queens on Non-square Tori" pptx

... one can obviously place at most m nonattacking queens and for 4 ≤ m<n,one can just take a solution on the m × m board and extend the board. Moreover, the reader will easily find solutions on ... reader will readily find that there is no solution on the 6 × 3 board, but there are solutions on the 9 × 3 board. It follows that there are solutions on the n × m board for all m<nwith...
