The error message says"c0000005 EXCEPTION_ACCESS_VIOLATION", and the error location is unknown. The following is my model. Looking forward to any advice.

Hi
can you try to replace ct4 by
forall(i in trips)
forall(j in trips:j>=i)
forall(k in trips:k>=i&&k<=j)
{ ct4:
1==sum(i in trips,j in trips:j>=i)
((chain[i][j]==1) && (contain[i][j][k]==1)) ;
}
or even
forall(i in trips)
forall(j in trips:j>=i)
forall(k in trips:k>=i&&k<=j)
{ ct4:
1==sum(i in trips,j in trips:j>=i)
((chain[i][j]+contain[i][j][k]==2)) ;
}
?
regards
Thanks to AlexFleischer. The expression as your suggestion is beyond me. But I have modified my model according to your suggestion and tried to run it.It seems to need very long time to obtain the result, since it have been running for more than 40 minute. I will tell you the result when I get it.
I am grateful to see your reply. You have helped me so much.
After more than 2-hour running, the programming turns out a error again with the error message says "not enough memory" . And the error comes from the expression of ct4. I have attached the screenshots for the error message and the ct4. I will keep on looking for the right way to accomplish it .
