Graph reduction machine

In computer science, graph reduction implements an efficient version of non-strict evaluation, an evaluation strategy where the arguments to a function are not immediately evaluated. This form of non-strict evaluation is also known as lazy evaluation and used in functional programming languages. The … See more A simple example of evaluating an arithmetic expression follows: The above reduction sequence employs a strategy known as outermost tree reduction.
