For the syntax-based decoding algorithms, n-best list extraction is done with 
algorithm 3 from this paper:

  Liang Huang and David Chiang
   "Better k-best parsing"
   In Proceedings of IWPT 2005

For phrase-based SMT, Philipp's textbook has a very readable description of the 
algorithm (section 9.1.3).
