Y combinator in scheme blows up using Church numbers, but works on regular numbers

QUESTION

Y combinator in scheme blows up using Church numbers, but works on regular numbers

Asked 2021-Apr-23 at 09:54

I've just read "A Tutorial Introduction to the Lambda Calculus1" by Raul Rojas. I put the lambda expressions into Scheme (TinyScheme) to try them out. Everything worked except the recursive function to calculate the sum of the Church numbers 0,1,...,N using the Y-combinator which runs out of memory. Bizarrely, the Y-combinator works if I calculate the sum using regular numbers.

Here is my Y-combinator,

The lambda calculus only works with normal order reduction (i.e. arguments are only evaluated when their values are needed), and Scheme uses applicative order reduction (arguments are evaluated first), except in "special forms".

Your code works with regular numbers not because of the numbers, but because of cond, which will evaluate at most one of its clauses.

If you replace the cond in your sum1 with a regular function, your computation will not terminate with regular numbers either.

Vulnerabilities

No vulnerabilities reported

Install tinyscheme

Install "Visual C++ 2010" or later.
I compiled using "Visual C++ 2010 Express Edition SP1", but "2008" or earlier maybe OK.
Open the Visual Studio command prompt, or open Normal command prompt then run. and change directory to unpacking source files.
To build an executable, just run.
To build as a static library, run with "static" option.
