Dear All, 

 

How can I get controlled seeds in a expression like this?

 

 (let ((r-lis nil))
         (dotimes (i 4)
           (push (rnd-unique 5 '(1 2 3 4 5)) r-lis))
         r-lis)

 

This will result four different seeds (one for each loop iteration), like this:

 

rnd-unique :seed 361914
rnd-unique :seed 275956
rnd-unique :seed 883737
rnd-unique :seed 46981
((3 1 4 5 2) (4 2 1 5 3) (2 5 4 1 3) (1 3 5 4 2))

 

And this will result the same seed for all four iterations:

 

 (let ((r-lis nil))
         (dotimes (i 4)
           (push (rnd-unique 5 '(1 2 3 4 5):seed 1) r-lis))
         r-lis)

 Like this:

 

rnd-unique :seed 1
rnd-unique :seed 1
rnd-unique :seed 1
rnd-unique :seed 1
((3 1 5 4 2) (3 1 5 4 2) (3 1 5 4 2) (3 1 5 4 2))

 

How to make it with a specific seed chosen for each loop iteration?

 

THIS WON´T WORK...

 

 (let ((r-lis nil))
         (dotimes (i 4)
           (push (rnd-unique 5 '(1 2 3 4 5):seed '(1 23 467 11)) r-lis))
         r-lis)

 

All the best !

Thank you !

Julio

 

(let ((seed '(1 23 467 11)))
  (loop for i in seed
    collect (rnd-unique 5 '(1 2 3 4 5) :seed i))
  )

 

Thanks, Janusz !

Best,

Julio
