The Runtime Complexity (full) of the given CpxTRS could be proven to be BOUNDS(n^1, n^1).


The TRS R consists of the following rules:

   active(f(X, g(X), Y)) -> mark(f(Y, Y, Y))
   active(g(b)) -> mark(c)
   active(b) -> mark(c)
   active(g(X)) -> g(active(X))
   g(mark(X)) -> mark(g(X))
   proper(f(X1, X2, X3)) -> f(proper(X1), proper(X2), proper(X3))
   proper(g(X)) -> g(proper(X))
   proper(b) -> ok(b)
   proper(c) -> ok(c)
   f(ok(X1), ok(X2), ok(X3)) -> ok(f(X1, X2, X3))
   g(ok(X)) -> ok(g(X))
   top(mark(X)) -> top(proper(X))
   top(ok(X)) -> top(active(X))

S is empty.

(1) NestedDefinedSymbolProof (UPPER BOUND(ID))
The following defined symbols can occur below the 0th argument of top: proper, active
The following defined symbols can occur below the 0th argument of proper: proper, active
The following defined symbols can occur below the 0th argument of active: proper, active

Hence, the left-hand sides of the following rules are not basic-reachable and can be removed:
active(f(X, g(X), Y)) -> mark(f(Y, Y, Y))
active(g(b)) -> mark(c)
active(g(X)) -> g(active(X))
proper(f(X1, X2, X3)) -> f(proper(X1), proper(X2), proper(X3))
proper(g(X)) -> g(proper(X))

(5) CpxTrsMatchBoundsTAProof (FINISHED)
A linear upper bound on the runtime complexity of the TRS R could be shown with a Match-Bound[TAB_LEFTLINEAR,TAB_NONLEFTLINEAR] (for contructor-based start-terms) of 4. 

The compatible tree automaton used to show the Match-Boundedness (for constructor-based start-terms) is represented by: 
final states : [1, 2, 3, 4, 5]

(13) RewriteLemmaProof (LOWER BOUND(ID))
Proved the following rewrite lemma:
g(gen_mark:b:c:ok3_0(+(1, n11_0))) -> *4_0, rt in Omega(n11_0)

Induction Base:
g(gen_mark:b:c:ok3_0(+(1, 0)))

Induction Step:
g(gen_mark:b:c:ok3_0(+(1, +(n11_0, 1)))) ->_R^Omega(1)
mark(g(gen_mark:b:c:ok3_0(+(1, n11_0)))) ->_IH
mark(*4_0)

We have rt in Omega(n^1) and sz in O(n). Thus, we have irc_R in Omega(n).
