% Problem  : Quo vadis 7 - an unreachable state
% Version  : Especial.
% English  : bb is big block (square, size=4 tiles).
%            s1-s4 : 4 small square blocks, size=1 tile
%            v1-v4: 4 vertical blocks, size= 2 tiles
%            b1: horizontal block, size= 2 tiles
%            e1, e2 are the 2 blank tiles
%            It's a 5x4 playing field to move from the start state to
%            the goal state. This is a simple goal for testing.
