if you want a nitpick, my personal preference is one line of dashes "-" to a line of "= and/or +". either way thanks for doing this

I tried - first, it looked a bit weak. At least for me, = acts better up to its name as divider 😄

[YigitElma]

This looks so much better!

I think the line breaks \n are excessive since we already separate the sections with the diving line ====, but I'm fine with it if everyone else prefers having the line breaks

It is again up to the general vote, but I feel like, especially when you run something like solve_continuation_automatic, our stdouts get too long and I would like to make them modularized.

requested changes were made

I am going to be annoying but could we have a line break btwn objectives so you can tell them apart? otherwise it is just like 100 numbers and they are far from the objective names that say what each are...

[dpanici]

Nevermind, the units help distinguish

run black and flake8 on repo then we will commit
