Comment:
Helloooo Dima,
Here is a first-pass review:
- Where exactly is the 'twograph' module to be found in the documentation?
It
does not belong to the main 'design' page.
- `is_regular_twograph` -- the first sentence of the docstring must be
short
(one line) and describe what the function does.
- doc of `descendant`: a sentence starts with an upper-case letter. Same
with
`complement()`, `twograph_descendant()`
- {{{``self.ground_set()``}}} -- should be a link.
- `is_twograph` -- you should rephrase the first sentence of the doc. An
INPUT
block is missing.
- Construction of chang graphs by switching: define K8 and T8 in the block
that
does that, not in the previous doc which does not use them.
- {{{:meth:`sage.matrix.change_ring`}}} -- broken link (appears twice)
- `seidel_matrix` INPUT for Graph: you must add doctests to test that it
works,
and to test your exceptions.
- {{{is_two_graph_descendant_of_srg}}} - what about those `v0,k0,l0,mu0`
we
already mentionned? `v,k,l,mu` would be easier to read.
