Q DP problem:
The TRS P consists of the following rules:
new_mapFM(vy3, Branch(vy40, vy41, vy42, vy43, vy44), h, ba, bb) → new_mapFM(vy3, vy43, h, ba, bb)
new_mapFM(vy3, Branch(vy40, vy41, vy42, vy43, vy44), h, ba, bb) → new_mapFM(vy3, vy44, h, ba, bb)
R is empty.
Q is empty.
We have to consider all minimal (P,Q,R)-chains.
By using the subterm criterion [20] together with the size-change analysis [32] we have proven that there are no infinite chains for this DP problem. From the DPs we obtained the following set of size-change graphs:
- new_mapFM(vy3, Branch(vy40, vy41, vy42, vy43, vy44), h, ba, bb) → new_mapFM(vy3, vy44, h, ba, bb)
The graph contains the following edges 1 >= 1, 2 > 2, 3 >= 3, 4 >= 4, 5 >= 5
- new_mapFM(vy3, Branch(vy40, vy41, vy42, vy43, vy44), h, ba, bb) → new_mapFM(vy3, vy43, h, ba, bb)
The graph contains the following edges 1 >= 1, 2 > 2, 3 >= 3, 4 >= 4, 5 >= 5
