The algebraic structures of the genetic code are most important to obtain additional information about the semantic code and its applications. In this paper we define two dual Boolean codon lattices of the genetic code using hydrogen bond numbers and the chemical types of bases: purines and pyrimidines. The Boolean lattices reflect the role of hydrophobicity in the distribution of codon assignm...

Evolution and the diversification of organisms are made possible by codes, or arbitrary assignments of “meaning,” in multiple ways. Many are not widely appreciated. Codes allow the same system of components to be used for multiple purposes. These can be open-ended, the way the alphabet and vocabulary make this column possible, but the flexibility of a code can become constrained once a system w...

One method for compacting executable computer code is to replace commonly repeated sequences of instructions with macro instructions from a decoding dictionary. The size of the decoding dictionary is often small in comparison to the number of all possible macros. Choosing the macros that yield the best compaction is a di cult subset selection problem because multiple, but colliding, macros may ...
