WebJul 23, 2014 · Recall that Church encoding can be understood as repeated application of a function to an argument. So to add m + n, we need to apply a function f to an argument x m + n times, or equivalently apply it n times and then apply it m times:. def add_church(m, n): def m_plus_n(f): def f_repeated_m_plus_n_times(x) # f ** (m + n) intermediate_result = … WebMogensen–Scott encoding. In computer science, Scott encoding is a way to represent (recursive) data types in the lambda calculus. Church encoding performs a similar function. The data and operators form a mathematical structure which is embedded in the lambda calculus. Whereas Church encoding starts with representations of the basic data ...
