Re: [eclipse-clp-users] 7.11 puzzle

Hi,
I added 	A #>= B, B #>= C, C #> D,
to the Puzzle to discard symmetrical solutions and to speed up  :

Eclipse on Mac (Snow Leopard) :
[eclipse 5]: 
		Sum = 711,
		Product = 711,
   		Prices = [A, B, C, D],
   		A #> 0, B #> 0, C #> 0, D #> 0,		
		A #>= B, B #>= C, C #> D, 
		A + B + C + D #= Sum,
   		A * B * C * D #= Product * 1000000,
   		labeling(Prices),
   		writeln(Prices).									
		[316, 150, 125, 120]

		Sum = 711
		Product = 711
		Prices = [316, 150, 125, 120]
		A = 316
		B = 150
		C = 125
		D = 120
	
Yes (10.92s cpu, solution 1, maybe more) ? 

But, without that, I get an answer (then times more !)  : 
	==> Yes (111.26s cpu, solution 1, maybe more) ? 

Cheers

Alex
