Hi Sai,

This is nice. A little more background in the notebooks about how the optimization problem is obtained would be nice.

Combustion instabilities are an interesting topic:

It may be of interest to find out if there are any models for Soyuz:

Hey all,

Looks like the notebook has really caught some attention. I wanted to post some updates here (more on the blog coming soon).

You can find the merged notebook here <https://github.com/mlpack/examples/tree/master/rocket_injector_design>. It will be much easier to run it on a binder <http://lab.mlpack.org/> instance. I've detailed the story behind its motivation and how Multi-objective optimizers help solve it. There's also reference youtube videos, research papers and Github repository in the notebook.

*TODO:*
    1. Since the Pareto Front is 3D we want, zoomable, rotatable, interactive graphs. Library: Bokeh <https://docs.bokeh.org/en/latest/index.html>. (Thanks to Marcus's effort for the SoS kernel).
     2.  The magnum opus, to have a rocket injector simulator. \
                         * Design part is working.
                        * Simulating the mixing displays strange behaviour, going for particle simulation might need GPU.
    3. Blogging about it.

Best
Sai

    This is super cool!  I'm looking forward to seeing the finished
    notebook. :)
