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) g`1(x,g`2(a,b)) -> g`1(b,g`2(b,a))

[2]  All the rules of this TRS can be oriented with RPO with the following precedence:
Status: g`1: Lex-RL, g`2: Lex-LR, 
Precedence:
a > b
