This paper proposes a new DNA algorithm for solving N-Queen problem, a complex optimization problem. The algorithm not only shows whether or not a solution exists, but provides all possible solutions by massively parallel computations. The proposed algorithm can be easily extended to solve other ...

Determine whether the current situation is illegal, and return immediately if it is illegal. This step is also called an integrity check (Sanity Check). For example, check whether the current processing situation is out of bounds, and whether there is a situation that does not meet the conditi...

We continue to return to the problem of backtracking. The most classic problem of backtracking is Queen N, which is also the most difficult problem. It is similar to the problem of solving Sudoku, but they are all similar. We will still use Queen N as a representative to understand this ...
