Hi  I need to implement following features for solving a MIP  Main goal here is to generate cuts from integral LP solutions to master problem using integer subproblems throughout the tree. My maste...

Hello, I am running Gurobi to solve a Lagrangian Decomposition algorithm in which I divide the problem into subproblems 1 and 2 named as m1 and m2 in Gurobi. Both are minimization problems. Summati...

Hello, I am trying to implement Branch and Benders Cut algorithm using GurobiPy. I do have the problem separated into master and sub problems. Since it is a mixed integer problem I need to implemen...

Hello, I am using Gurobipy to solve LP and I want to refer to a constraint to call the .pi attribute.  For a single constraint such as  constr = sub.addConstr(y1 - y2 == 0); I can refer to the pi a...

I am trying to code a simple objective function which works fine. I read that quicksum() isn't the best way to model large objective function. I would like to know how I can model my objective func...

Hello,   Please take a look at attached photo. What are the things that I can try to speed up the process. I have everything coded in gurobi-python. Are there things that I can try with Gurobi func...

Hello,    I am trying to work on a model after it is created inside a function and returned   Example: def createmodel(params): m = Model() x = m.addVar(vtype = GRB.BINARY) m.addConstr(con...

Hi, I have a MIP problem coded in python. Following is a code for illustration def problem(): m = Model() add variables : x = {} add constraints: ax <=b add objective: min cTx m.optimize() return ...
