I have a non-linear optimization problem that I can formulate in excel or python but I have a difficult time solving it since my optimization skills are rusty. The problem has roughly 200 integer variables that are bounded [-6, 6]. The objective function is non-convex. I need someone to help me solve the problem in python. I suspect it might be possible using this package: [login to view URL] In fact, I wrote the problem is so that this package can use it but I seem to get stuck in at local minimums that are clearly not correct. Please message me with any questions.

I've some quick questions for you: 1) Have you tried any meta heuristics way like GA, let's say (they tend to take their own sweet time,. it usually give you a global optimum) 2) Have you tried linearization of the function, and then solving it using any out of the shelf solver I guess matrix operations can be done with numpy itself. The objective is important here. Thanks! About me: Being a research student in robotics and machine learning, I deal with a lot of non-convex optimization problems everyday. Sometimes, it is easy as choosing a kernel trick and sometimes it's bit lengthy...and sometimes we are happy with the local minima itself as it is much better than any other we know.

I can solve the problem with some metaheuristic method (e.g. genetic algorithm or simulated annealing). They can help avoiding local optima. I'll solve it in Python even if it is formulated in Excel. Relevant Skills and Experience PhD in optimization (of energy supply systems) using various methods. Good knowledge of Python and Excel and their optimization tools. Proposed Milestones $160 USD - Solving the optimization problem. Additional Services Offered $200 USD - Consulting related to applied optimization. Since your problem is non-convex, integer and relatively large, I suggest attempting to use metaheuristic methods. They **don't guarantee** obtaining global optima, but in practice they usually find either the **optimal solution or some good near-optimal solution**. After such solution is obtained one might try to further improve it with local search. There are several more tricks. These methods are very popular in both scientific and practical applications. Additionally, they let us be more flexible when formulating problems and choosing optimization tools. Whether the problem is formulated in Excel or Python, I'd solve it with the Python solver. If it is in Excel, I can also try solving it inside Excel, without additional apps (this depends on the problem, Excel version, etc.). Please, have in mind that I'm not going to use Python 2 (since I'm not comfortable with it), only Python 3!
