    Gurobi stuck in root node.

    Ongoing

    I am trying to get the results for a Unit Commitment problem. I am doing test for various planning horizons i.e. using data for 1 week, 1 month, 2 months, 3months etc. I am able to get a solution f...

    Thanks for all the help Jaromił, it is greatly appreciated. You were right about the symmetry issue, something I myself was unaware off. However, after doing some research last night, I came across...

    Thanks for the feedback Jaromił. Based on the equality constraints mentioned above, I know this is associated with my load demand constraints where the sum of the power generated by each unit in th...

    Hi Jaromil, yes I understand that this problem is quite large, so I have no problem with a MIPGap of 1%. Since my previous comment, I have included PreQLinearize = 1, Method = 0, SimplexPricing ...

    Hi Jaromil, thanks for the response. I believe that the lower bound should be improved. So I am trying the simulation over without turning off Cuts and MIPFocus = 3. I got the mps file, it can be f...

    Answered

    I am working on solving Unit Commitment problem. I am using Gurobi as the solver and Julia to create the model (MIQP model). However, I have been running the solver for a little over 24hours and no...
