Query: Successive-Cancellation Decoding of Binary Polar Codes Based on
  Symmetric Parametrization   This paper introduces algorithms for the successive-cancellation decoding and
the successive-cancellation list decoding of binary polar source/channel codes.
By using the symmetric parametrization of conditional probability, we reduce
both space and time complexity compared to the original algorithm introduced by
Tal and Vardy.
