Does anyone know where I could find research papers on lossless compression methods that aren't based on the old standby concepts (namely, Lempel-Ziv and Huffman), aside from Burrows-Wheeler? I'd be particularly interested in knowing if there are any compression schemes based on something like Godel numbers, i.e. something that heavily suggests bytecode embedded in the compressed stream (I'm not sure what to call this... operational compression?)...
