ah! I fixed it by writing:It's much faster now! Thans for i in range(N-1):     for k in range(i+1, N):         g.addConstr(gu.quicksum((x[i,s,:] @ x[k,s,:].T) for s in range(q)) <= q*(1-C), name = ...

Thank you for the reply. However I am confused - I have N(N-1)/2 1-dim constraint, each constraint resulting from the restriction of minimum distant between any (i,j), 1<=i<j<=N, pair of binary mat...
