ParMOO: A Python library for multiobjective simulation optimization (w/ @SciWild) is published in JOSS!
Our 2nd release (v 0.2.0) is on GitHub: github.com/parmoo/parmoo
At Argonne, we use this for expensive design optimization problems, such as material engineering
Just published in JOSS: 'ParMOO: A Python library for parallel multiobjective simulation optimization' doi.org/10.21105/joss.04468

Given the pervasiveness of sensors and #data, derivative-free #optimization is becoming necessary in more and more domains. In SIAM News, @SciWild explores the techniques involved in such problems as well a #materials discovery application. Check it out! sinews.siam.org/Details-Page…
ALT A schematic of an online optimization process for a materials engineering laboratory that involves an optimization solver called ParMOO.

If you aren't familiar with name Sophie Chang, you might be seeing it in record books soon.
The 25yo American scores an impressive upset over Ana Konjuh, 7-6 (5), 3-6, 7-6 (7).
And, if the serve gun is to be believed, ties the fastest ever serve on the WTA tour at 136mph!

@kkimopt and I have a new #postdoc opening at @argonne to develop randomized algorithms for massive discrete optimization problems, see: tinyurl.com/4vspvuzr (US citizenship or residency NOT required)

More than two years later, the last chapter of my dissertation is finally published! 😍 dl.acm.org/doi/10.1145/35701… As far as I know, this is now the state-of-the-art for monotonicity preserving spline interpolation software (1D). Fast, reliable, and twice differentiable.😎

The quantum group at the Global Technology Applied Research center at JPMorgan Chase is hiring (summer internship and full time positions available)! We do a lot of exciting fundamental and applied research into quantum algorithms and their applications to financial use cases.

I just finished helping my former PhD advisor, Layne Watson, upload all of his all numerical software packages to GitHub: github.com/vtopt
These are all published ACM TOMS algorithms, written in modern #Fortran
My dissertation code VTMOP is also available here.
In general, you will find codes for #interpolation, #optimization, and #homotopy methods for solving #nonlinear systems of equations
Is there a way to tell my MacBook to never use clang for any reason ever again, including building Python packages, makefiles, etc? I have the compilers and libraries that I want from brew, and I really don’t want to use the clang version of anything

Was recently asked what are some important theoretical research questions that can be addressed in ML right now, "fundamental" / generally applicable ones. I'll focus in on differentiable compute graphs & optimizers here (neural network training) here are 6 directions:

By chance, I just found these beautiful cheatsheets for Matplotlib with Python: matplotlib.org/cheatsheets/
Might be useful for those of us who struggle remembering how to get Matplotlib to do what we want...
A week late, but wanted to announce the initial release for ParMOO: Python library for parallel multiobjective simulation optimization
