BUILDING

To build queens, run:

    make

This will construct the executable and ensure that runTrials.sh has the correct permissions.

USAGE

The default behavior will perform a hill-climbing search of the N-queens problem and output the resultant board and the number of attacking queens. Full usage instructions for queens are as below. You can also get usage instructions by running queens -?.

    queens [-rcq?] [-d N]
        -r      Use random restarts to find solution
        -q      Suppress printing the board and number of
                attacking queens
        -d N	Sets the board dimension and number of
                queens to N (Default = 8)
        -?	    Print this usage message

Note that queens is fairly stupid in its options checking, so please only feed it integers when using the -d option. Also note that board sizes over ~20 tend to have rather long running times.
