Reminds me of Julia's Pkg manager and the way Julia packages are managed (also with a .toml file). That's the way to go!

Cool idea! Thanks for the hint, I would have not thought of that.

yes, geospatial could be interesting. The tools depend on what the university / lecturer prefers, for me it was Julia for programming in math courses, JuMP.jl for optimization modeling, Python for ML courses.

I think cross-specializing with physics of energy might be quite cool. Then I could work on problems such as, e.g.,

- optimizing the placement of wind turbines to maximize energy capture

- determining the optimal size and type of solar panels for a given area.

Ask HN: Is Operations Research still a thing?

samuel2 — Wed, 29 Jan 2025 13:20:49 +0000

Hi HN,

I am currently looking for internships / junior positions in OR but there is almost nothing, even though the technology (e.g. integer linear solvers) had huge improvements over the last decade. There are open source implementations (e.g. HiGHS) and modeling languages (JuMP.jl) making it possible to solve complex decision problems at almost no cost.

- Why is the interest in optimization models not exploding in the industry?

- Is OR a promising field to specialize in?

- What is the best strategy to connect with OR practitioners?

Thanks for your insights!

Ask HN: Getting into Energy Industry with Math Background

samuel2 — Tue, 30 Jan 2024 19:17:26 +0000

Hi! I have academic background in math - optimization, stats, machine learning & have programming skills. I am considering to specialize in optimization for energy industry. What resources could you recommend to get started? Are there any solid textbooks on physics / engineering that you would recommend?

Thanks!

Probably the most elegant math book I have ever seen is Probabilty theory a graduate course by Achim Klenke. A very nice exposition into the abstract, measure theoretic prob. thoery (but it assumes some prior knowledge).

If you are into numerical optimization, a nice source of intersting problems and examples (that e.g. contradict the intuition) can be found in

Mathematical Tapas: Volume 1 and Vol. 2.

Intersting comment, but I think there might be fluctuations around a growing overall demand.
