Alphabet: !plus : [nat * nat] --> nat 0 : [] --> nat dec : [nat * nat] --> nat grec : [nat * nat * nat * nat -> nat -> nat] --> nat log2 : [nat * nat] --> nat s : [nat] --> nat sumlog : [nat] --> nat Rules: dec(0, x) => 0 dec(x, 0) => x dec(s(x), s(y)) => dec(x, y) grec(0, x, y, f) => y grec(s(x), s(y), z, f) => grec(dec(x, y), s(y), f z x, f) sumlog(x) => grec(x, s(s(0)), 0, /\y./\z.!plus(log2(s(z), 0), y)) !plus(0, x) => x !plus(s(x), y) => s(!plus(x, y)) log2(s(0), 0) => 0 log2(0, s(x)) => s(log2(s(x), 0)) log2(s(0), s(x)) => s(log2(s(x), 0)) log2(s(s(x)), y) => log2(x, s(y)) This AFS is converted to an AFSM simply by replacing all free variables by meta-variables (with arity 0).
