Hi Xin Yu, Thank you for sharing the model! This looks a hard model. From the following code snippet:  m.setObjective(r[0] * t, gp.GRB.MAXIMIZE) m.addConstr(t * r[3] == 1) the objective function ca...

Hi, Bounds are now computed. It's the first step!Then, the value of the Incumbent solution(=12.48982) and the value of Bounds are far apart. Which value is assumed to be closer to objective functio...

Hi, The warning is shown in your log: Warning: Model contains variables with very large bounds participating in product terms. Presolve was not able to compute smaller bounds for ...

In addition, when H=23, cap=12.500125 is obtained, at which time the objective function is 309.77262. Here, as we restrict the value of cap to smaller values, the objective value worsens to 310.319...

Hi, On my side, the cap value is 12.50012500 when H=4, and it will be 12.159504406436357 after I set H = 24.(Not sure if this is the correct way to set this up. And for H greater than 25, the probl...

Hi, Thank you for sharing random data! It took some code modifications(resolving SyntaxError), but it worked here too. Since you have the condition "soc[i] <= 0.9 * cap", the position of the eps se...

Hi, Thank you for sharing the code! Unfortunately, I cannot run the code on my side, because of the lack of some input data. If it is difficult to share reproducible code (code with data) here, cou...

Hi, That's a little strange. Could you please share the full code? Note that uploading files directly in the Community Forum is not possible but we discuss an alternative in Posting to the Communit...

Hi Maximilian, The error: unsupported operand types for TempConstr and tupledict/int or tupledict and int means that the object type does not correspond to the method, as the sentence refers to. In...

Hi, This article might help: How do I diagnose a wrong result? Also, I suggest you start by sorting out what the current situation is. For example: What constraints are you trying to write? What v...
