Generate random MIN and MAX value from a range of values

bharathwajan

Hi All,

 I would like to know if there is any efficient way to generate a random min and max value from a range of  values?

i have a range VAL1 to VAL2... I need to generate a min_val and max_value within this range such that min_val >=VAL1 and max_val>min_val and max_val<=VAL2 

I am not able to use a variable in the keep constraint.

keep MIN_VAL  in [VAL1.. VAL2]

keep MAX_VAL in [MIN_VAL  .. VAL2] -- NOT POSSIBLE

 So is there any work around without using 'gen' inside while? 

 

Thank you !!!

 

Cheers,

Bharath.

    Why not just tell the solver what you just told us?

    keep min_val >= VAL1;

    keep min_val < max_val;

    keep max_val <= VAL2;

    You don't gain any efficiency from using "in" or reducing the number of constraints here. VAL1 and VAL2 can be variables or constants.
