 %arg syntax

 parameters:

 numStaff := 30;
 numDayInCycle := 21;

 S := 1..numStaff;
 D := 1..numDayInCycle;

 variables:
 n[S]: binary;
 z[S,D]: binary;

 objectives:
 numstaff: sum{s in S: n[s]} -> min;


 constraints:
 {s in S: sum{d in D: z[s,d]} <= n[s]*1 ;} #this is ok
 {s in S: sum{d in D: z[s,d]} <= n[s] / 1 ;} #error
