Hi Xiao, Can you try using the latest version (v11.0.1) and setting the parameter FuncNonlinear=1 (instead of the ones you are setting) Cheers, David

Hi Liu, You can parse and plot the log using gurobi-logtools. import gurobi_logtools as gltresults = glt.parse("yourlog.log")glt.plot(results.progress("nodelog")) See the full example in the gurobi...

Hi Moisés, I don't think this is possible from Python.This can be from C, methods discussed in Advanced simplex routines Cheers, David

Hi Peilin, In that case you can use user cuts (instead of lazy cuts), however these will not remain for the next solve.One way to keep these would be to save them in a separate container and add th...

Hi Peilin, You can add some lazy cuts to achieve this.See our TSP example: modeling-examples/traveling_salesman/tsp.ipynb at master · Gurobi/modeling-examples or, tsp.py Cheers, David

Hi Zhao, You can use the matrix API: Model.addMVar() Example: matrix1.py Cheers, David

Hi Yifeng, Do you mean something like this: In Python: import gurobipy as gpeducation = list(range(5))gender = list(range(5))idx = list(range(5))with gp.Model() as m:    x = m.addVars(education, ge...

See a similar post in the Julia discourse. In your case, you can use the GRBaddgenconstrLog which is documented here: GRBaddgenconstrLog - C API. Cheers, David

Thanks for reporting this. We will track this in an internal ticket. Cheers, David

You can try and model your logic using binary variables. What are you trying to model with the tuple? This is not clear, as \(\texttt{q_gtw}\) is a continuous variable, you need to add an expressio...
