+// Part 2 about finding a single tour for a board using the Warnsdorf Rule

+// !!! Copy any function you need from file knight1.scala !!!
+//
+// If you need any auxiliary function, feel free to 
+// implement it, but do not make any changes to the
+// templates below.

+type Pos = (Int, Int)    // a position on a chessboard 
+type Path = List[Pos]    // a path...a list of positions
+
+
+//(6) Complete the function that calculates a list of onward
+//    moves like in (2) but orders them according to Warnsdorf’s 
+//    rule. That means moves with the fewest legal onward moves 
+//    should come first.
+
+
+//def ordered_moves(dim: Int, path: Path, x: Pos) : List[Pos] = ..
+
+
+//(7) Complete the function that searches for a single *closed* 
+//    tour using the ordered_moves function from (6). This
+//    function will be tested on a 6 x 6 board. 
+
+
+//def first_closed_tour_heuristic(dim: Int, path: Path) : Option[Path] = ...
+
+
+//(8) Same as (7) but searches for *non-closed* tours. This 
+//    version of the function will be called with dimensions of 
+//    up to 30 * 30.
