The classical form of Reed-Muller logic is based on sum-of-products-style representations, in which XOR gates replace OR gates. You can also implement functions using only XOR and XNOR gates, which I ...

Various logic gates—AND, OR, XOR, NAND, NOT, CNOT, and a half adder—could be put together using different combinations of robots. The DNA gates all take two inputs in the form of other molecules.
