The rewrite relation of the following TRS is considered.
a(x1) | → | b(x1) | (1) |
b(b(c(x1))) | → | c(a(c(b(b(x1))))) | (2) |
c(c(x1)) | → | x1 | (3) |
a#(x1) | → | b#(x1) | (4) |
b#(b(c(x1))) | → | c#(a(c(b(b(x1))))) | (5) |
b#(b(c(x1))) | → | a#(c(b(b(x1)))) | (6) |
b#(b(c(x1))) | → | c#(b(b(x1))) | (7) |
b#(b(c(x1))) | → | b#(b(x1)) | (8) |
b#(b(c(x1))) | → | b#(x1) | (9) |
The dependency pairs are split into 1 component.
b#(b(c(x1))) | → | a#(c(b(b(x1)))) | (6) |
a#(x1) | → | b#(x1) | (4) |
b#(b(c(x1))) | → | b#(b(x1)) | (8) |
b#(b(c(x1))) | → | b#(x1) | (9) |
[b#(x1)] | = |

[a(x1)] | = |

a#(x1) | → | b#(x1) | (4) |
The dependency pairs are split into 1 component.
b#(b(c(x1))) | → | b#(x1) | (9) |
b#(b(c(x1))) | → | b#(b(x1)) | (8) |
[b#(x1)] | = |

b#(b(c(x1))) | → | b#(b(x1)) | (8) |
[b(x1)] | = | 1 · x1 |
[c(x1)] | = | 1 · x1 |
[b#(x1)] | = | 1 · x1 |
Using size-change termination in combination with the subterm criterion one obtains the following initial size-change graphs.
b#(b(c(x1))) | → | b#(x1) | (9) |
1 | > | 1 |
As there is no critical graph in the transitive closure, there are no infinite chains.
