Total derivatives notation is exactly what I needed for my problem! thanks :)

I think I got the answer to the original question, but still can't tell what is $z$.. For example $f(x,y)=x+y=x+x^2$, where's $z$?

@J.M. If I understand correctly, you're basically saying that on the left side I used partial derivative instead of total? (meaning that it should have been ($\frac{df}{dx}$ rather than $\frac{\partial f}{\partial x}$)

OK, I do understand that for a string of length N I have Fibonacci(N-1) different symbols in the input alphabet. What I don't understand is why I need to compare these strings to the corresponding unrestricted ones. What I mean is that as far as I'm concerned, I could send Fib(N-1) fruit and vegetable types, which would be decoded into bits on the other side - who cares how many bits we had at the input?
