Comment (by mkoeppe):
Thanks for taking a look.
Replying to [comment:2 novoselt]:
> As I have said before - `ELLUL` is not necessarily the best name in the
first place and for revised dictionaries it just does not make sense.
Agreed that ELLUL is not a good name. But there's value in a routine that
does "one pivot + output" as a subroutine of the simplex method with
output.
> So how about:
> - do not add new stupidly named methods (I am allowed to call `ELLUL`
stupid since I've invented it ;-))
> - add `run_simplex_method` and `run_dual_simplex_method` to abstract
dictionaries with implementation relying on abstract methods only [...]
Yes.
> - simplify `run_simplex_method` etc in the problems that will now build
a bigger HTMLFragment based on the stuff returned from dictionaries.
Agreed.
> In 6.9 it is possible to create `HTMLFragments` [....]
This sounds like a good direction.
> How does this sound? I am happy to implement the above for current
dictionaries and leave you the dual ones.
Sounds good.
