Term Rewriting System R:
[x, y, z]
.(.(x, y), z) -> .(x, .(y, z))

Innermost Termination of R to be shown.



   R
Dependency Pair Analysis



R contains the following Dependency Pairs:

.'(.(x, y), z) -> .'(x, .(y, z))
.'(.(x, y), z) -> .'(y, z)

Furthermore, R contains one SCC.

DPs
       →DP Problem 1
Usable Rules (Innermost)


Dependency Pair:

.'(.(x, y), z) -> .'(y, z)


Rule:


.(.(x, y), z) -> .(x, .(y, z))


Strategy:

innermost




As we are in the innermost case, we can delete all 1 non-usable-rules.

Size-Change Principle


Dependency Pair:

.'(.(x, y), z) -> .'(y, z)


Rule:

none


Strategy:

innermost




We number the DPs as follows:
  1. .'(.(x, y), z) -> .'(y, z)
and get the following Size-Change Graph(s):
{1} , {1}
1>1
2=2

which lead(s) to this/these maximal multigraph(s):
{1} , {1}
1>1
2=2

DP: empty set
Oriented Rules: none

We used the order Homeomorphic Embedding Order with Non-Strict Precedence.
trivial

with Argument Filtering System:
.(x1, x2) -> .(x1, x2)

We obtain no new DP problems.
