Hi, Sorry that is not possible and I cannot see how to model it easily. Best Christian

Subject: [gecode-users] probability to apply constraint

 

Hello,

Is it possible to apply a constraint with a probability associated?

For example I have an array of 10 integers which has two constraint :

1) The sum should be equal to 100;

2) The numbers of even array index should be equal to 0.

 

To the 2) constraint, I would like to add a probability saying that the constraint apply in 80% of the cases.

I know that what could work would be for each even array index to pick a number between 0 and 100 and apply the rule dynamically depending on the number picked (<80 -> apply, otherwise doesn'y apply).

However, I would like to know if there would be a more elegant way.

 

Cheers

 

Richard
