It doesn't have to be completely random but deviates from the optimal solution, if I have an objective function. In the above case, the model picks "n best solutions", which is too biased. Is it po...

What is the most efficient way to generate a random solution from all possible solutions that comply with some constraints in a MIP?
Awaiting user inputHello, I am not very familiar with MIP and LP. I want to have a random sample from all possible solutions that satisfy some linear constraints. There is an example code using JuMP from Julia: using...

Hi Simranjit Kaur, I tried your suggestion and found that my model works similarly to a "PoolSearchMode" of 2, which get n best solutions. Is it possible for the model to get random extra solutions...

How does 'PoolSearchMode=1' works in a MIP problem? (using JuMP from Julia)
AnsweredAs mentioned, I want to find all possible solutions that satisfy some linear constraints. More specifically, I want to get a random choice in all these solutions. I then found that setting a `PoolS...
