I would like to add this instruction constraint: if a=b then c<d  else c>d when a=b → k =1  a !=b → k =0 I know how to handle such situations if a<b then c<d else c>d But I'm confused about how...

Hi，I want to take the remainder of the variable.     for k in orders:      m.addConstr(t[k.no] % 7 + 1 == k.rk % 7) t is the decision variable. But it returns the following error TypeError: unsup...

I want to set the following objective function： and it contains the condition that where is the decision variable. My code is as follows dep_1 = gp.quicksum((k.hk * h[k.no, t] for k in orders...

HiWhen I add the following constraint and execute it, an error occurs：  for k in orders:       for t in range(1, 60):            if t <= k.rk:                m.addConstr((t <= tao[k.no]) * (h[k.no...
