@dima: could you check that variable logLnr is always assigned a value in methods bliss_graph_from_labelled_edges and bliss_digraph_from_labelled_edges. I seems that it might be used uninitialized...

Dima, see comment:1.

David, Micro-optimization, but since you know cdef list done = [False] * n will be a length n array of bint's, you are better to directly allocate such an array (Cython generates better C code and you do not have the overhead of list).

  • Status changed from needs_review to needs_work

I will do that. I also did a mistake in initializations. I will fix that.

Ready for review.

comment:6 Changed 5 months ago by dimpase

It seems to be a good idea to declare logLnr as 

cdef int logLnr = 0

(in two places in src/sage/graphs/bliss.pyx)
