Yes, I did worked. Thankyou.

From some suggestions, I made all variables as Continuous and then I checked it. It works for minimization objective but not for maximization.

How to find absolute difference of list and use those values in maximization optimization model guobipy?
Answered#Following is my code where I try absolute operations of two lists based on some conditions and then maximize the summation of those.m=[5,3,2]cm=[sum(m[0:x:1]) for x in range(1, len(m)+1)]P=len(m)p...

How to acheive cumulative sum of cumulative 3D arrays in gurobi python
Awaiting user inputSay I have X1 and X2 which is based on some operations between variables and parameters of the model and so X1 and X2 will be variables. x1=[[[1, 6], [2, 7], [3, 8], [4, 9], [5, 10]], [[1, 6], [2, ...

Hi Alison, I missed an important point in the previous query, i have changed two constraints according to my model which elapsed the solver time, its been more than 2 hours, I'm waiting for the sol...

Thank you Alison. Yes, i corrected that blunder mistake, now its feasible and now the issue is when the input of d=[11,1,1,1,1,1,1,1,1,1] and s=[12,9,6,6] as I commented in the code, the solver tak...

Why the following model showing infeasible in gurobipy when the same is solved optimally by MIP python open source solver? What am I missing ? Is it the operation between arrays and guobi variables the issue? How to find out?
