Edsger Dijkstraused this problem in 1972 to illustrate the power of what he calledstructured programming. He published a highly detailed description of the development of adepth-firstbacktracking algorithm.2 Below is one solution for 8 or N queen puzzle using C language description,you can define ...
Solving the N-queens problem using the Preempt-RT Raspbian Kernel in multi-thread configuration was 3.43 times faster on the Model B+ than using single-thread configuration. This factor increases slightly on Model B (3.48 times). Model B+ was 14% faster in multi-thread configuration and 16%...
