Dogelog Player is a Prolog system that is 100% written
in Prolog itself. It is avsailable for the JavaScript,
Python and Java platform. We show how the stable
ordering of Prolog variables in Dogelog Player allows
highly efficient constraint solving approaches.

We convert the undirected graph into a directed graph
and create adjacency lists. This inequality graph doesn’t
have the same delayed evaluation overhead than
(#=)/2 and dif/2. We demonstrate map coloring and
sudoku solving. Further improvements in a
subsequent article.
