BibTeX, Natbib, and Algorithm2e

Question

I'm trying to prepare a journal submission, and I'm having trouble getting natbib to play nicely.

1. When I include natbib in my document, it gives me the following error:

   ! Undefined control sequence
   \chapter ...ace{10\p@ }}\algocf@original@chapter
   
   l.1 \begin{thebibliography}{17}
   

   This isn't such a huge deal to me -- I'm fine working around it. The bigger problem that I have is...

2. When I disable natbib, the citation keys and references look horrible. For example, if I have the following bibtex entry

   @article{Day06,
       author = {T.E.~Day and J.T.~Napoli and P.C.~Kuo},
       title = {Scheduling the Resident 80-Hour Work Week: An Operations Research Algorithm},
       journal = {Current Surgery},
       volume = {63},
       number = {2},
       month = {Mar.-Apr.},
       year = {2006},
       pages = {136-141}
   }
   

   whenever I use \cite{Day06} it produces [Day et al(2006)Day, Napoli, and Kuo] in my text, which looks awful. Even worse, the entry in the references section looks terrible, too:

   [Day et al(2006)Day, Napoli, and Kuo] Day T, Napoli J, Kuo P (2006) Scheduling the resident 80-hour work week: An operations research algorithm. Current Surgery 63(2):136-141

   I don't know why it's including the (horribly-mangled) key in the citation next to the author list.

Any suggestions? Has anyone else dealt with this before?

Answer 1

Are you using MiKTeX or TeXLive? If you are using TeXLive can you tell me which version? To be frank it looks very similar to the fonts problem I had with natbib due to the outdated (2009) version of TeXLive I used. I updated to 2011 and the problems went a way.
