Q DP problem:
P is empty.
The TRS R consists of the following rules:

active1(f2(g1(X), Y)) -> mark1(f2(X, f2(g1(X), Y)))
active1(f2(X1, X2)) -> f2(active1(X1), X2)
active1(g1(X)) -> g1(active1(X))
f2(mark1(X1), X2) -> mark1(f2(X1, X2))
g1(mark1(X)) -> mark1(g1(X))
proper1(f2(X1, X2)) -> f2(proper1(X1), proper1(X2))
proper1(g1(X)) -> g1(proper1(X))
f2(ok1(X1), ok1(X2)) -> ok1(f2(X1, X2))
g1(ok1(X)) -> ok1(g1(X))
top1(mark1(X)) -> top1(proper1(X))
top1(ok1(X)) -> top1(active1(X))

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
The TRS P is empty. Hence, there is no (P,Q,R) chain.
