Problem 1: 

(VAR x)
(RULES
f(a,f(x,a)) -> f(f(a,f(f(a,a),x)),a)
)

Problem 1: 

Innermost Equivalent Processor:
-> Rules:
 f(a,f(x,a)) -> f(f(a,f(f(a,a),x)),a)
-> The term rewriting system is non-overlaping or locally confluent overlay system. Therefore, innermost termination implies termination.
 

Problem 1: 

Dependency Pairs Processor:
-> Pairs:
 F(a,f(x,a)) -> F(f(a,f(f(a,a),x)),a)
 F(a,f(x,a)) -> F(a,f(f(a,a),x))
-> Rules:
 f(a,f(x,a)) -> f(f(a,f(f(a,a),x)),a)

Problem 1: 

SCC Processor:
-> Pairs:
 F(a,f(x,a)) -> F(f(a,f(f(a,a),x)),a)
 F(a,f(x,a)) -> F(a,f(f(a,a),x))
-> Rules:
 f(a,f(x,a)) -> f(f(a,f(f(a,a),x)),a)
->Strongly Connected Components:
->->Cycle:

Problem 1: 

Reduction Pairs Processor:

 F(a,f(x,a)) -> F(a,f(f(a,a),x))
-> Rules:
 f(a,f(x,a)) -> f(f(a,f(f(a,a),x)),a)
-> Usable rules:
 f(a,f(x,a)) -> f(f(a,f(f(a,a),x)),a)
->Interpretation type:
 Linear
->Coefficients:
 All rationals
->Dimension:
 1
->Bound:

->Interpretation:
 
[f](X1,X2) = 1/3.X1 + 1/4.X2
[a] = 2/3
[F](X1,X2) = 1/2.X2

Problem 1: 

SCC Processor:
-> Pairs:

 f(a,f(x,a)) -> f(f(a,f(f(a,a),x)),a)
->Strongly Connected Components:
 There is no strongly connected component
