Implementing FGH efficiently stresses recursion, lazy evaluation, and memory management. Competing to compute ( f_\omega+1(5) ) symbolically is a brutal test for Haskell, Scheme, or Rust.
: Higher levels are created by repeatedly applying the previous level's function times. fast growing hierarchy calculator
Each function in the hierarchy grows significantly faster than the previous one, with the growth rate accelerating rapidly. For instance, F_3(x) grows much faster than F_2(x), which in turn grows much faster than F_1(x). Implementing FGH efficiently stresses recursion
