Suppressor Logic Toolkit and Quasi-Hash Function

Suppressor Logic Toolkit and Quasi-Hash Function

The following slides describe the basic toolkit design and a specific experiment that would result in a quasi-hash function

Basic Toolkit Design

The AND gate was designed by Anderson using termination suppressors, while the new design would use frame shift suppressors.

Toolkit with Specific Inputs and Outputs

PprpB/propionate and luxO/pluxT are new communication players that would need to be looked into further to verify their usefulness.
