```quote We can use the two examples in the mesa-examples repo: https://github.com/projectmesa/mesa-examples/tree/main/examples/boltzmann_wealth_model_experimental https://github.com/projectmesa/mesa-examples/tree/main/examples/schelling_experimental ``` I think it should be either one of them, and virus on a network or boid...

I have an alternative implementation to this PR, which requires a much smaller code diff. Basically I simply generated emoji_names.py from `emoji-datasource-x`. And so no change is needed for `tools/setup/emoji/build_emoji`...

> All new (new as in not present in the old emoji_names.py) emoji codes that have at least 2 '-'s, e.g. 1f469-200d-1f9af for woman_with_probing_cane are displayed as Ⓒ️. Any new...

! I have managed to display the `:woman_with_probing_cane:`. I earlier applied #19629 to default to Twitter, but didn't realize that my test user on my dev env still uses Google...

You basically just need to use this: https://github.com/scipy/scipy/blob/master/scipy/optimize/lbfgsb_src/lbfgsb.f and recompile.

You can view the licensing requirement of the 2011 version at https://github.com/scipy/scipy/blob/master/scipy/optimize/lbfgsb_src/README. I additionally have noticed 2 changes to the API: - the first argument of setulb, n, is gone...

That 2011 version already includes the modification. I have inspected the source code of http://www.ece.northwestern.edu/~nocedal/lbfgsb.html. It has the required `c-jlm-jn` comments. ``` c=========== L-BFGS-B (version 3.0. April 25, 2011 ===================...

Ah, I see. https://github.com/JuliaPackaging/Yggdrasil/blob/master/L/L_BFGS_B/build_tarballs.jl#L10 already uses the 3.0 version. I have also inspected the comment, also contains c-jlm-jn. But scipy.optimize's, lbfgsb.f is different since it has the extra `maxls` argument....

OK, basically the main differences are - `maxls` becomes a parameter instead of being hardcoded to 20. - `itfile` for iterate.dat is gone. The output is redirected to somewhere else....
