Figure out another way. Remember, you could decide to use fewer threads, in which case you'd explore the solution tree in less breadth, but you'd go faster in depth... Or you could start more threads, exploring the tree slower in terms of depth, but faster in terms of breadth... Maybe... :-) |

In order to do so, you will have to measure the timing of your version and compare it to the timing of the class N-Queens for several values of ''N''. | In order to do so, you will have to measure the timing of your version and compare it to the timing of the class N-Queens for several values of ''N''. | ||
