Term Rewriting System R:
[x, y, z]
g(f(x, y), z) -> f(x, g(y, z))
g(h(x, y), z) -> g(x, f(y, z))
g(x, h(y, z)) -> h(g(x, y), z)

Innermost Termination of R to be shown.

Removing Redundant Rules



Removing the following rules from R which fullfill a polynomial ordering:

g(f(x, y), z) -> f(x, g(y, z))
g(h(x, y), z) -> g(x, f(y, z))

where the Polynomial interpretation:
  POL(g(x1, x2))=  2·x1 + x2  
  POL(h(x1, x2))=  1 + x1 + x2  
  POL(f(x1, x2))=  1 + x1 + x2  
was used.

Not all Rules of R can be deleted, so we still have to regard a part of R.

Dependency Pair Analysis



R contains no Dependency Pairs and therefore no SCCs.
