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

TOP1(sent1(up1(x))) -> TOP1(check1(rec1(x)))
TOP1(rec1(up1(x))) -> TOP1(check1(rec1(x)))

The TRS R consists of the following rules:

rec1(rec1(x)) -> sent1(rec1(x))
rec1(sent1(x)) -> sent1(rec1(x))
rec1(no1(x)) -> sent1(rec1(x))
rec1(bot) -> up1(sent1(bot))

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
We use the reduction pair processor [13].


The following pairs can be oriented strictly and are deleted.


TOP1(rec1(up1(x))) -> TOP1(check1(rec1(x)))
The remaining pairs can at least be oriented weakly.

TOP1(sent1(up1(x))) -> TOP1(check1(rec1(x)))
Used ordering: Polynomial interpretation [21]:

POL(TOP1(x1)) = x1   
POL(bot) = 0   
POL(check1(x1)) = x1   
POL(no1(x1)) = 2·x1   
POL(rec1(x1)) = 1 + x1   
POL(sent1(x1)) = x1   
POL(up1(x1)) = 1 + x1   

The following usable rules [14] were oriented:

sent1(up1(x)) -> up1(sent1(x))
rec1(no1(x)) -> sent1(rec1(x))
check1(no1(x)) -> no1(x)
check1(rec1(x)) -> rec1(check1(x))
check1(sent1(x)) -> sent1(check1(x))
no1(up1(x)) -> up1(no1(x))
rec1(rec1(x)) -> sent1(rec1(x))
rec1(up1(x)) -> up1(rec1(x))
rec1(bot) -> up1(sent1(bot))
check1(no1(x)) -> no1(check1(x))
rec1(sent1(x)) -> sent1(rec1(x))
check1(up1(x)) -> up1(check1(x))
