Termination of the following Term Rewriting System could be proven:

Context-sensitive rewrite system:
The TRS R consists of the following rules:

f(b, X, c) → f(X, c, X)
cb

The replacement map contains the following entries:

f: {2}
b: empty set
c: empty set

Context-sensitive rewrite system:
The TRS R consists of the following rules:

f(b, X, c) → f(X, c, X)
cb

The replacement map contains the following entries:

f: {2}
b: empty set
c: empty set

Using Improved CS-DPs we result in the following initial Q-CSDP problem.

Q-restricted context-sensitive dependency pair problem:
For all symbols f in {f, F} we have µ(f) = {2}.

The ordinary context-sensitive dependency pairs DPo are:

F(b, X, c) → F(X, c, X)
F(b, X, c) → C

The TRS R consists of the following rules:

f(b, X, c) → f(X, c, X)
cb

Q is empty.

The approximation of the Context-Sensitive Dependency Graph contains 0 SCCs.
The rules F(b, z0, c) → F(z0, c, z0) and F(b, x0, c) → F(x0, c, x0) form no chain, because ECapµ(F(z0, c, z0)) = F(z0, x_1, z0) does not unify with F(b, x0, c). The rules F(b, z0, c) → F(z0, c, z0) and F(b, x0, c) → C form no chain, because ECapµ(F(z0, c, z0)) = F(z0, x_1, z0) does not unify with F(b, x0, c).
