    Thank you very much. I think this solution (the code) is very helpful and I can learn a lot from these codes.

    I noticed three are several posts discussing how to model conditional constraints with Gurobi. But there currently is not a particular example or demonstration how to model three conditions (and ev...

    Thank you for your professional input. I will continue to work on this problem. I currently have one more issue, for which I made a new post in this platform. Thanks again for your kind help.

    Hi Towle, I set the MIPGap parameter to see whether I can obtain a proper solution, instead of the time limit. Here is the updated code.  def OptimalTrajectory1(timesteps=20, initialSpeed=15, final...

    Three conditions in the objective function

    回答済み

    I am trying to model three conditions in the objective function, which is shown as below. In this function, alpha, beta1, beta2 and m are all constants and the rest of symbols represent variables t...

    This is the output of the model. It takes hours to obtain a proper solution. The arguments I passed to the OptimalTrajectory1 is the default values defined in the definition of the function, i.e., ...

    Thank you very much Mr. Towle, I have revised the bounds of power variable. And, according to the code warning, I set the mode.Param.NonCovex=2. Now, the model does not give me the model infeasible...
