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

HALF_2_IN_AA -> HALF_2_IN_AA

R is empty.
Q is empty.
We have to consider all (P,Q,R)-chains.
The head symbols of this DP problem are {HALF_2_IN_AA}.
With regard to the inferred argument filtering the predicates were used in the following modes:
log2₂: (f,b)
log2₃: (f,b,b) (b,b,b)
half₂: (f,f) (b,f)
