Short version Given the $N$ code lengths of an optimal prefix-free code $L[1..N]$ for $N$ unknown weights $W[1..N]$ of known sum $S$, and $N'$ new weights $W'[1..N']$ all larger than the weights ...
An affix code is a code that is simultaneously a prefix and suffix code. That is, no codeword is neither the prefix nor the suffix of any other codeword. Affix codes can be instantaneously decoded in ...
A prefix-free function is one whose domain is prefix-free. Similarly, a prefix-free (Turing) machine is one whose domain is prefix-free. It is usual to consider such a machine as being ...
What is the best upper bound known for the complexity of computing an optimal prefix free code in the RAM model?
In the algebraic decision tree, the result is clear: Elmasry and Belal (Verification Of Minimum Redundancy Prefix Codes)'s lower bound shows that the worst case complexity of computing an optimal ...
