Trying variety of Solvers

[mayar]

hello there,

I have been looking for some solver to try with my problem ( non convex NLP)
After finishing the modelling stage, I was really impressed by the easiness of using a solver like Ipopt with JuMP, but now to look for a global optimum point, I am interested to try other solvers like COUENNE or BARON for example… but I have had problem linking Julia with these solvers and the license issue…I need some help or guide.

Thank you in advance

I think this request might be a bit too broad to get meaningful help - it’s probably best to start specific threads for specific issues with specific solvers (including code that reproduces your errors where applicable) so that people can help you.

Latest recommendations for global optimization

What are people’s recommendations for a global optimizer? I’m trying to do simulated method of moments (choosing a set of parameters for an economic model to minimise the distance between model predictions and data) and have so far been using blackboxoptim. I find it somewhat unreliable: running exactly the same code on the same data I find sometimes the optimizer gives me a parameter choice that provides a close fit to the data, but sometimes it just seems to get stuck without converging). Any …

… but, as nilshg pointed out: the question is a bit broad. Much depends on the optimization problem you are trying to solve.
