The Most Likely Optimal Symmetric RVLC
Sayed Jalal Zahabi, Mohammadali Khosravifard · IEEE Transactions on Communications · 2015
For each alphabet size up to 30, a symmetric reversible variable length code (RVLC) is determined which is most likely to be optimal in average codeword length. It is shown that these codes are optimal for more than half of all the possible sources.
