Johnson decoder

Here is a model of a parameterized /V-bit Johnson decoder with an enable control.

Synthesized netlist for a 3-bit Johnson decoder is // shown in Figure 3-22. 

In the held of protein similarity May and Johnson have devised a GA for protein structure comparison.Their binary string GA encodes three translations and three rigid body rotations. On decoding an individual a transformation is generated to superimpose one protein on top of another. The htness function uses a dynamic programming technique to determine topological equivalences.
