Term Rewriting System R:
[x, y, z]
+(-(x, y), z) -> -(+(x, z), y)
-(+(x, y), y) -> x
Innermost Termination of R to be shown.
R
↳Dependency Pair Analysis
R contains the following Dependency Pairs:
+'(-(x, y), z) -> -'(+(x, z), y)
+'(-(x, y), z) -> +'(x, z)
Furthermore, R contains one SCC.

↳Usable Rules (Innermost)
Dependency Pair:
+'(-(x, y), z) -> +'(x, z)
Rules:
+(-(x, y), z) -> -(+(x, z), y)
-(+(x, y), y) -> x
Strategy:
innermost
As we are in the innermost case, we can delete all 2 non-usable-rules.

↳Size-Change Principle
Dependency Pair:
+'(-(x, y), z) -> +'(x, z)
Rule:
none
Strategy:
innermost
We number the DPs as follows:
- +'(-(x, y), z) -> +'(x, z)
and get the following Size-Change Graph(s):
which lead(s) to this/these maximal multigraph(s):
D_{P}: empty set
Oriented Rules: none
We used the order Homeomorphic Embedding Order with Non-Strict Precedence.
trivial
with Argument Filtering System:
-(x_{1}, x_{2}) -> -(x_{1}, x_{2})
We obtain no new DP problems.
