Replace integer arithmetic with more complex expressions. For example, the following identities can be used to encode integer addition:
x + y = x  ¬ y  1 = (x ⊕ y) + 2·(x ∧ y) = (x ∨ y) + (x ∧ y) = 2·(x ∨ y)  (x ⊕ y)
For example, Tigress might replace
z = x + y + wwith
z = (((x ^ y) + ((x & y) << 1))  w) + (((x ^ y) + ((x & y) << 1)) & w);
Diversity
For each operator, there are many possible encodings, and at transformation time, these are selected from randomly.
