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(g(X)) -> g(f(f(X)))
(2) f(h(X)) -> h(g(X))

[2]  Reverse every lhs and rhs of the rule to obtain the following TRS:
(1) g(f(X)) -> f(f(g(X)))
(2) h(f(X)) -> g(h(X))

[3]  All the rules of this TRS can be oriented with RPO with the following precedence:
Precedence:
g > f
h > g
