Thanks for reporting!

It is because source block evaluation is disabled on server side when
generating WORG website from org sources.

You basically need to evaluate the code block manually to have it
present in the original file without a need to evaluate during export.

I do not have maxima on my system. It would be welcome if you evaluate
the code blocks with missing results manually and submit a patch with.

No, the source block in the Solver section is different. It just has
the same name. Name duplicate should be fixed indeed.

Makes sense. Can you please report this inconsistency in more details in
a separate email? It looks like something is not right with ob-maxima
code in the treatment of :results graphics.

Using graphics together with file does not make sense.
We should probably fix ob-maxima with :results file first.
Ideally, the code here should be simply
,#+header: :results file

This will break WORG page. We are exporting to HTML, not latex and the
results wrapped into #+begin_export latex will not be exported to the
website. What's wrong with raw?
