If source produces symbol 'a' 25% of times symbol 'b' 25% of times symbol 'c' 50% of times THEN after eg 1,000 symbols sequences generated ( total N # of symbols within these 1,000 sequences ) THEN can with very high confidence level says the # of 'a' will be around N/4 the # of 'b' will be around N/4 the # of 'c' will be around N/2 > > > 2. compresses these eg 1,000 generated sequences using your .exe , & must decode back to the same 1,000 sequences > > Does the decompressor know, in advance, the exact number of bits in > the > sequence?

Right? Good luck! :-) > > I'll leave my bet on Shannon, Kraft, and the pigeons. SO WOULD I should these 1,000 sequences being 'random' structureless .... here the structure is within each sequence the # of 'c' is EXACT = the # of 'b' + 2 IN FACT ... all sequence MUST END with a 'c' , immediate before this 'c' ONLY an 'a' OR a 'c' can occur [ NEVER a 'b' ! ] .... if you look more careful, there are many more restrictions on possible permutations 'ordered'arrangements between the # of 'a's & 'b' & 'c' within a sequence , eg if there are 6 symbols in a sequence 1st 2 symbols cant be both 'a's & last 3 symbols cant be ALL 'b's .... etc so forth .... IT IS THESE THAT MAY MAKE YOUR SOUGHT FOR 1.420bits/token p[ossible achievable ( ? ) > > James Dow Allen
