Term Rewriting System R:
[x, y]
f(x, a(b(y))) -> f(c(d(x)), y)
f(c(x), y) -> f(x, a(y))
f(d(x), y) -> f(x, b(y))
Termination of R to be shown.
R
↳Dependency Pair Analysis
R contains the following Dependency Pairs:
F(x, a(b(y))) -> F(c(d(x)), y)
F(c(x), y) -> F(x, a(y))
F(d(x), y) -> F(x, b(y))
Furthermore, R contains one SCC.

↳Remaining Obligation(s)
The following remains to be proven:
Dependency Pairs:
F(d(x), y) -> F(x, b(y))
F(c(x), y) -> F(x, a(y))
F(x, a(b(y))) -> F(c(d(x)), y)
Rules:
f(x, a(b(y))) -> f(c(d(x)), y)
f(c(x), y) -> f(x, a(y))
f(d(x), y) -> f(x, b(y))
Termination of R could not be shown.
