Is it possible to intersect a set with an array of sets in CPLEX opl? I've posted some of the code above.

Hi,

could

range course=1..j;
range conflict=1..p;

int CourseIDs[i in course]=i;
{int} CourseConflict[c in conflict]={c,c+1,c+2} ;
 
{int} ConflictSetIntersection[c in conflict]=
union (i in course ) {CourseIDs[i] }inter CourseConflict[c];

execute
{
writeln(ConflictSetIntersection);
}

help ?

regards
