Hi, Jaromił Thanks for your reply! In the above code, we did not fix b or q, but optimized b and q simultaneously. For this code, if we fix b to optimize q, the simulation time will be faster, whil...

Hi, Jaromił, the code is shown as follows. from gurobipy import *import gurobipy as gpfrom numpy import *import numpy as npimport mathimport random#define global variablesglobal KK = 10global MM =...

Hi，Jaromił I want to know why the code runs very slowly when solving variable b with fixed variable q, but solving q with fixed variable b is faster？These two variables have similar forms in the ...

Hi, Jaromił Thanks for your reply! In gurobi, if I want the solver to output the results when the Incumbent remains unchanged for N times and the Incumbent is not infeasible, instead of waiting unt...

Hi, Jaromił, I provide the results of the code interruption obj and the output variables q and b. Set parameter NonConvex to value 2Set parameter ScaleFlag to value 2Set parameter Aggregate to valu...

Hi, Jaromił My original optimization objective is as follows, with optimization variables highlighted in red underline. In order to meet the solving requirements of gurobi, we have introduced many...

Hi, Jaromił The main problem I want to solve is the alternating iteration of the following two problems. The first one is to solve q with fixed b, and the second one is to solve b with fixed q. Opt...

Hi, Maliheh, Connect to the previous post,  Although scaling variables and "multiply both sides of the equation by 1e3" can avoid some warnings, they greatly prolong the simulation time, resulting ...

Hi, Maliheh, My optimization problem is as follows, and optimization variables are underlined in red.    First, because the lower bound of my variables v and t can reach 1e-10, which is smaller th...

Hi, Maliheh, Thank you for your reply! Regarding your comments, I would like to ask a few questions. (1) It is not possible to have strict inequality constraints in Gurobi, if the variable "b>0" no...
