YES

The TRS could be proven terminating. The proof took 36 ms.

The following DP Processors were used


Problem 1 was processed with processor DependencyGraph (3ms).
 | – Problem 2 was processed with processor SubtermCriterion (1ms).
 | – Problem 3 was processed with processor SubtermCriterion (0ms).

Problem 1: DependencyGraph



Dependency Pair Problem

Dependency Pairs

sum#(s(x))sum#(x)sum1#(s(x))sum1#(x)

Rewrite Rules

sum(0)0sum(s(x))+(sum(x), s(x))
sum1(0)0sum1(s(x))s(+(sum1(x), +(x, x)))

Original Signature

Termination of terms over the following signature is verified: 0, s, sum1, sum, +

Strategy


The following SCCs where found

sum#(s(x)) → sum#(x)

sum1#(s(x)) → sum1#(x)

Problem 2: SubtermCriterion



Dependency Pair Problem

Dependency Pairs

sum#(s(x))sum#(x)

Rewrite Rules

sum(0)0sum(s(x))+(sum(x), s(x))
sum1(0)0sum1(s(x))s(+(sum1(x), +(x, x)))

Original Signature

Termination of terms over the following signature is verified: 0, s, sum1, sum, +

Strategy


Projection

The following projection was used:

Thus, the following dependency pairs are removed:

sum#(s(x))sum#(x)

Problem 3: SubtermCriterion



Dependency Pair Problem

Dependency Pairs

sum1#(s(x))sum1#(x)

Rewrite Rules

sum(0)0sum(s(x))+(sum(x), s(x))
sum1(0)0sum1(s(x))s(+(sum1(x), +(x, x)))

Original Signature

Termination of terms over the following signature is verified: 0, s, sum1, sum, +

Strategy


Projection

The following projection was used:

Thus, the following dependency pairs are removed:

sum1#(s(x))sum1#(x)
