Seems to work if I change getValue(h)[1:n] (and others) to getValue(h)[:].

You can embed metadata in .ipynb files. I added a "keywords" entry to the DualNumbers notebooks. Is this useful? How can we make the notebooks indexable and searchable?

Develop a policy for licences, what we accept, recommend, etc. Creative commons is applicable to documentation and educational materials, but not applicable if the notebook contains code itself that is meant to be reusable.

Opening this to keep track of notebooks which haven't been updated yet for the big renaming in JuMP 0.13.

It would be nice to have some sort of tests on the notebooks to make sure they produce the expected output and don't suffer from bit rot over time.

This helps making it more accessible for anyone to run the code directly, wherever the notebooks aren't using any solver-specific functionality.

I could send a few PR's for this, but it'd be by editing ipynb files in nano since I don't actually use IJulia myself.

• Berkeley nonlinear
• IAP2015
• NRM example

Don't have a TSP one as a notebook I think, but we should.

Some of the links are broken due to pages being moved or deleted over time. Here are some I have found till now:

• Missing figure in Chiwei Yan - Cutting Stock
• Author website link in notebooks by Shuvomoy Das Gupta

Some of the latex equations of two IJulia notebooks: exploiting sparsity and column generation are not being rendered properly in Nbviewer. In IJulia, they are correctly viewed, in fact when I uploaded them to Github, the rendering on nbviewer was correct.

Can you please suggest how do I fix this?

Credits to original authors can go inside the notebooks.
