[gecode-users] element constraint

[frank lemoine]

hi gecode users,

 

thank you christian for tips about the element constraint i run it, it's a very usefull but still i had some difficulties i don't know if gecode provide a solution for representing two intvar by a single intvar.

 

let this constaint element (home, a,b,c)

 

i have two integer variables represented by Intvar, i want to use a variable Intvar in c that can represent the link between this two varaibles (an edge for example)  

the goal is to check if this pair is in a the set of all pairs in a

have some one an idea  ?
