Help Information

dennis@dennis-laptop:~$ fmps --help
  fmps {OPTIONS} [rules...]

    solves the new funky math problem found in uWaterloo mathNEWS publication.
    Pass the program the size (defaults to 6) and the set of rules/restrictions,
    if there is a valid solution, it will be printed out.
    Rules are in the following format:
    <x1>:<y1>:<x2>:<y2>:<rule>
    Where:
    <x1> - The horizontal index of the first box affected by the rule.
    <y1> - The vertical index of the first box affected by the rule.
    <x2> - The horizontal index of the second box affected by the rule.
    <y2> - The vertical index of the second box affected by the rule.
    <rule> - The rule, either "<", ">" or a number for the absolute difference
    Note: Boxes are zero indexed, beggining with the upper left box.
    Example:
    0:1:0:2:3 - The first two boxes of the first column must have a difference
    of 3

      -s[size], --size=[size]           Set the size of the grid
      -a, --all                         Find all solutions, not just the first
      -c, --count                       Only count the solutions, do not print
                                        them
      -m, --metrics                     Output some metrics about the
                                        solution(s)
      rules...                          The list of constraints/rules
      "--" can be used to terminate flag options and force all following
      arguments to be treated as positional options

Example

Here is an example run:
