Problems implementing the power function
ユーザーの入力を待っています。Hello, I am currently trying to model the following context in Gurobi. \(App_{pd}=0.5+0.5(1-S_{pd}^{-p})\) The code of the constraints looks something like this. help = Model.addVars(P, D, lb=...

Implementation of sub-problem aggregation makes the problem unfeasible
ユーザーの入力を待っています。I am facing a weird problem. I am currently implementing a column generation heuristic with aggregated sub-problems (for those that are identical). I use this model decomposition and this aggregati...

How to implement a linear approximation?
回答済みHello, I have the following question. I would like to implement a non-linear relationship in my model as a linear approximation. I want to approximate this function linearly. \(c_{i} = \exp^{-0.5\t...

Separate access to the dual values of various constraints
回答済みHello, I have the following model. from gurobipy import *model = Model()I = [1,2,3]J = [1,2,3]D = [1,2,3]# Variablesx = model.addVars(I, J, D, vtype=GRB.BINARY, name="x")y = model.addVars(J, D, vt...
