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?

from the ask-hn dept.

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...

Ask HN: Getting into Energy Industry with Math Background

Posted by samuel2 on Tuesday January 30, 2024 @02:17PM
from the ask-hn dept.

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!

Re:Ask HN: Math books that made you significantly better at math? on Thursday January 19, 2023 @10:47AM (#34441556)
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.

Would Rust be worth learning for implementing (numerical) optimization algorithms?

Ask HN: Literature for mathematical optimization?

Posted by samuel2 on Saturday July 03, 2021 @03:16AM
from the ask-hn dept.

Hi! Do you know any books on math optimization that are essential for anybody getting into this field? Is there any classical literature for optimization related to ML? Thanks!My current list includes:1. Numerical Optimization by Jorge Nocedal Stephen J. Wright2. Algorithms for Optimization - introduction to optimization with a focus on practical algorithms3. Algorithms for Decision Making ...

Re:Ask HN: Any suggestions for math projects? (Math Ventures Club) on Monday June 28, 2021 @07:48AM (#27660609)
This stuff seems to be very powerful!

Many applications stem from a simple observation: if two activities must be performed consecutively then the time required to complete both is the sum of the individual times, but if they may be performed concurrently then the time required is the maximum of the individual times.
