Result: TRS is terminating

Default interpretations for symbols are not printed. For polynomial interpretations
and semantic labelling over N\{0,1} defaults are 2 for constants, identity for unary
symbols and x+y-2 for binary symbols. For semantic labelling over {0,1} (booleans)
defaults are 0 for constants, identity for unary symbols and disjunction for binary symbols.

[1]  TRS loaded from input file:
(1) f(f(X)) -> f(g(f(g(f(X)))))
(2) f(g(f(X))) -> f(g(X))

[2]  Label this TRS using following interpretation over N\{0,1}:
[f(x)] = 3
[g(x)] = 2
rest default

  This interpretation is a model and yields following TRS:
(1) f{3}(f{i}(X)) -> f{2}(g{3}(f{2}(g{3}(f{i}(X)))))
(2) f{2}(g{3}(f{i}(X))) -> f{2}(g{i}(X))

[3]  All the rules of this TRS can be oriented with RPO with the following precedence:
Precedence:
f{i} > f{k} for i > k
f{i} > g{k} for all i, k
g{i} = g{k} for all i, k
