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) from(X) -> cons(X,n__from(s(X)))
(2) sel(0,cons(X,Y)) -> X
(3) sel(s(X),cons(Y,Z)) -> sel(X,activate(Z))
(4) from(X) -> n__from(X)
(5) activate(n__from(X)) -> from(X)
(6) activate(X) -> X

[2]  All the rules of this TRS can be oriented with RPO with the following precedence:
Status: sel: Lex-LR, 
Precedence:
from > cons
from > n__from
from > s
activate > from
sel > activate
