YES
The TRS could be proven terminating. The proof took 20 ms.
The following DP Processors were used
Problem 1 was processed with processor DependencyGraph (8ms).
| – Problem 2 was processed with processor SubtermCriterion (1ms).
Problem 1: DependencyGraph
Dependency Pair Problem
Dependency Pairs
| f#(f(x)) | → | f#(x) | | f#(f(x)) | → | f#(d(f(x))) |
| f#(f(x)) | → | f#(c(f(x))) | | g#(c(0)) | → | g#(d(1)) |
| g#(c(1)) | → | g#(d(0)) |
Rewrite Rules
| f(f(x)) | → | f(c(f(x))) | | f(f(x)) | → | f(d(f(x))) |
| g(c(x)) | → | x | | g(d(x)) | → | x |
| g(c(0)) | → | g(d(1)) | | g(c(1)) | → | g(d(0)) |
Original Signature
Termination of terms over the following signature is verified: f, g, d, 1, 0, c
Strategy
The following SCCs where found

Dependency Pairs
Rewrite Rules
| f(f(x)) | → | f(c(f(x))) | | f(f(x)) | → | f(d(f(x))) |
| g(c(x)) | → | x | | g(d(x)) | → | x |
| g(c(0)) | → | g(d(1)) | | g(c(1)) | → | g(d(0)) |
Original Signature
Termination of terms over the following signature is verified: f, g, d, 1, 0, c
