"WHITE CROSS - YELLOW CROSS" METHOD

1) YELLOW CENTER AT TOP, DRAW A WHITE CROSS
   PREPARE THE 4 WHITE EDGES:
   . MOVE THE 4 WHITE EDGES AROUND THE YELLOW CENTER
     >>> ALGO #1 FLIPS THE FRONT TOP EDGE
     
   . FOR EACH EDGE:
     - ROTATE THE TOP LAYER IN ORDER TO GET A COLORED SIDE JUST ABOVE
       THE CENTER IN THE SAME COLOR, AND ROTATE 180 DEGREES THE LAYER OF THIS CENTER
       (WHITE EDGE IS NOW DOWWARDS)
       
   . WHEN THE 4 WHITE EDGES ARE DOWNWARDS, TURN THE CUBE 180 DEGREES :
     - WE HAVE NOW A WHITE CROSS (CENTER AND 4 EDGES) UPWARDS WITH ITS ADJUSTED EDGES

2) CUBE, WHITE CENTER AT TOP, ADJUST THE 4 CORNERS
   . IF RIGHT UPPER CORNER OF FRONT LAYER IS NOT ADJUSTED, DETERMINE ITS COLORS:
     THESE OF THE 3 CONTIGNOUS CENTERS
     - LOOK FOR THIS CORNER IN THE CUBE
     - 1 TO 3 SUBTLE ROTATIONS SHOULD MOVE THIS CORNER UNDER ITS TOP RIGHT TARGET POSITION
   . ALGO #2 AS MANY TIMES AS NECESSARY TO GET THIS CORNER ADJUSTED AT TOP RIGHT POSITION
       
AT THIS STAGE THE WHITE UP LAYER IS TUNED

3) YELLOW CENTER AT TOP, FRONT LAYERS: ADJUST THE EQUATORIAL EDGES
   . ROTATE UPPER LAYER LOOKING FOR AN UPPER EDGE TO BE MOVED WETHER TO THE EQUATORIAL RIGHT OR LEFT SIDE
     OF THE FRONT LAYER
     - ALGO #3 TO MOVE THIS EDGE TOWARDS THE EQUATORIAL RIGHT SIDE (INCLUDES A 90 DEGREES RIGHT ROTATION)
     - ALGO #4 TO MOVE THIS EDGE TOWARDS THE EQUATORIAL LEFT SIDE (INCLUDES A 90 DEGREES LEFT ROTATION)
     
AT THIS STAGE, THE EQUATORIAL LAYER IS TUNED

4) YELLOW CENTER AT TOP, DRAW A YELLOW CROSS
   . VISUAL APPEARANCE OF THE YELLOW TOP LAYER:
     - THE CENTER ONLY IS YELLOW
       OR A REVERSED YELLOW 'L' : ALGO #5.1
     - AN HORIZONTAL YELLOW BAR IN THE MIDDLE (3 PIECES) : ALGO #5.2

AT THIS STAGE, WE HAVE A YELLOW CROSS WHOSE EDGES AND CORNERS NEED TO BE ADJUSTED

5) YELLOW CENTER AT TOP, ADJUST EDGES
	 AS LONG AS THE 4 EDGES OF THE TOP LAYER ARE NOT ADJUSTED :
   . ORIENT THE CUBE SO THAT THE ONLY REAR EDGE MUST REMAIN FIXED
     - ALGO #6.1 TOP LAYER, LEFT EDGE PIECE, FRONT AND RIGHT FOR A CLOCKWISE MOVE
     - ALGO #6.2 TOP LAYER, LEFT EDGE PIECE, FRONT AND RIGHT FOR A COUNTER-CLOCKWISE MOVE
     
6) YELLOW CENTER AT TOP, SET CORNERS AT RIGHT PLACE
	 AS LONG AS THE 4 CORNERS OF THE TOP LAYER ARE NOT AT RIGHT PLACE :
	 . WHILE RUNNING ALGORITHM MAINTAINS THE ONLY UPPER RIGHT FRONT CORNER PIECE AT SAME POSITION
	 	 SO, YOU MUST ORIENT THE CUBE TO THE SUITABLE POSITION, BEFORE IT MOVES THE 3 OTHER CORNERS PIECES
     - ALGO #7.1 FOR A CLOCKWISE MOVE
     - ALGO #7.2 FOR A COUNTER-CLOCKWISE MOVE

AT THIS STAGE, IF CUBE IS NOT ADJUSTED, LET'S TUNE IT

7) YELLOW CENTER AT TOP,
   . UPPER LAYER, LOOK FOR A FIRST NOT ADJUSTED CORNER :
     BY ROTATING CUBE, MOVE THIS CORNER IN RIGHT TOP POSITION OF FRONT LAYER
     - ALGO #8 UNTIL ITS YELLOW SIDE IS UPWARDS
       IF CUBE IS NOT ADJUSTED YET THEN ROTATE TOP LAYER (U) IN ORDER TO GET
       A NOT ADJUSTED CORNER PIECE AT TOP POSITION OF FRONT LAYER, AND TRY ALGO #8 AGAIN

END.
