[gecode-users] Classify the solutions

Please read about branchers in MPG: they are used in the order in which they
are posted.

Hi,

 

How can i branch the "sum" variable over the variable that represent the
vector of solutions ?

 

Thanks.

Hi,

 

What you could do is adding a "sum" variable and branch over the variable so
that values are tried in increasing order. Then the solutions will be found
in that order.

 

Best

Hello, 

i'm building a model , and the solutions are vectors like this "3 5 9 4 7",
i have an constraint that express the sum of the vectors must to be > than
an threshold M. 

My question is can i add an constraint or any parameter to tell to gecode :
the solutions returned must be ordered according to a criterion, for example
from the smallest to the largest sum.

 

Thank you for your help
