Q DP problem:
The TRS P consists of the following rules:

1024_11(x) → IF(lt(x, s(s(s(s(s(s(s(s(s(s(double(double(0))))))))))))), x)
IF(true, x) → 1024_11(s(x))

The TRS R consists of the following rules:

double(s(x)) → s(s(double(x)))
lt(0, s(y)) → true
lt(x, 0) → false
lt(s(x), s(y)) → lt(x, y)
double(0) → 0

The set Q consists of the following terms:

lt(0, s(x0))
lt(x0, 0)
lt(s(x0), s(x1))
double(0)
double(s(x0))

We have to consider all minimal (P,Q,R)-chains.
By rewriting [15] the rule 1024_11(x) → IF(lt(x, s(s(s(s(s(s(s(s(s(s(double(double(0))))))))))))), x) at position [0,1,0,0,0,0,0,0,0,0,0,0,0] we obtained the following new rules:

1024_11(x) → IF(lt(x, s(s(s(s(s(s(s(s(s(s(double(0)))))))))))), x)

Q DP problem:
The TRS P consists of the following rules:

IF(true, x) → 1024_11(s(x))
1024_11(x) → IF(lt(x, s(s(s(s(s(s(s(s(s(s(double(0)))))))))))), x)

The TRS R consists of the following rules:

double(s(x)) → s(s(double(x)))
lt(0, s(y)) → true

The set Q consists of the following terms:

lt(0, s(x0))
lt(x0, 0)
lt(s(x0), s(x1))
double(0)
double(s(x0))

We have to consider all minimal (P,Q,R)-chains.
As all Q-normal forms are R-normal forms we are in the innermost case. Hence, by the usable rules processor [15] we can delete all non-usable rules [17] from R.

Q DP problem:
The TRS P consists of the following rules:

IF(true, x) → 1024_11(s(x))
1024_11(x) → IF(lt(x, s(s(s(s(s(s(s(s(s(s(0))))))))))), x)

The TRS R consists of the following rules:

lt(0, s(y)) → true

lt(x, 0) → false

The set Q consists of the following terms:

lt(0, s(x0))
lt(x0, 0)
lt(s(x0), s(x1))

We have to consider all minimal (P,Q,R)-chains.
In the following pairs the term without variables s(s(s(s(s(s(s(s(s(s(0)))))))))) is replaced by the fresh variable x_removed.
Pair: 1024_11(x) → IF(lt(x, s(s(s(s(s(s(s(s(s(s(0))))))))))), x)
Positions in right side of the pair: The new variable was added to all pairs as a new argument[13].

Q DP problem:
The TRS P consists of the following rules:

1024_11(x, x_removed) → IF(lt(x, x_removed), x, x_removed)
IF(true, x, x_removed) → 1024_11(s(x), x_removed)

The TRS R consists of the following rules:

lt(0, s(y)) → true
lt(s(x), s(y)) → lt(x, y)
lt(x, 0) → false

The set Q consists of the following terms:

lt(0, s(x0))
lt(x0, 0)
lt(s(x0), s(x1))

We have to consider all minimal (P,Q,R)-chains.
The DP Problem is simplified using the Induction Calculus [18] with the following steps:
Note that final constraints are written in bold face.


For Pair IF(true, x, x_removed) → 1024_11(s(x), x_removed) the following chains were created:




For Pair 1024_11(x, x_removed) → IF(lt(x, x_removed), x, x_removed) the following chains were created:




To summarize, we get the following constraints P for the following pairs.



The constraints for P> respective Pbound are constructed from P where we just replace every occurence of "t ≥ s" in P by "t > s" respective "t ≥ c". Here c stands for the fresh constant used for Pbound.
Using the following integer polynomial ordering the resulting constraints can be solved
Polynomial interpretation [18]:

POL(0) = 0   
POL(1024_11(x1, x2)) = -1 - x1 + x2   
POL(IF(x1, x2, x3)) = -1 - x2 + x3   
POL(c) = -2   
POL(false) = 0   
POL(lt(x1, x2)) = 0   
POL(s(x1)) = 1 + x1   
POL(true) = 1   

The following pairs are in P>:

IF(true, x, x_removed) → 1024_11(s(x), x_removed)
The following pairs are in Pbound:

IF(true, x, x_removed) → 1024_11(s(x), x_removed)
There are no usable rules
