hello, experts.
I am a student. and recently, I read a paper about *Actor Model of
Computation:Scalable Robust Information System*. In the paper I am trying
to understand it's concept. But with the following sentence makes me
confusing.
# Messages are the unit of communication *1*
Reference to *1*
All physically computable functions can be implemented using the lambda
calculus. It is a consequence of the Actor Model that* there are some
computations that cannot be implemented in the lambda calculus*.
*My question*, What are there computations that cannot be implemented in
Lambda calculus ?
thanks.
Minglei.
