Here is an interesting scenario. I’m playing around with how copy works in JuMP.
#make dummy model m=Model(); @variable(m,x); c1=@constraint(m,x<=10); c2=@constraint(m,x<=100); delete(m,c1) delete(m,c2) #readd constraints c1=@constraint(m,x<=10); c2=@constraint(m,x<=100); m2=copy(m);
The constraint indices for
m are 3 and 4. On the other hand the constraint indices on
m2 (copy) get reset to 1 and 2. Is this the expected behavior in JuMP? Why not keep the indices from one copy to the other? I’m sure there are good reasons for this, I’m just curious.
