(0)
Obligation:
The Runtime Complexity (parallel-innermost) of the given CpxTRS could be proven to be BOUNDS(1, n^1).


The TRS R consists of the following rules:

   a__f(f(a)) -> c(f(g(f(a))))
   mark(f(X)) -> a__f(mark(X))
   mark(a) -> a
   mark(c(X)) -> c(X)
   mark(g(X)) -> g(mark(X))
   a__f(X) -> f(X)

S is empty.
Rewrite Strategy: PARALLEL_INNERMOST

(2)
Obligation:
The Runtime Complexity (parallel-innermost) of the given CpxTRS could be proven to be BOUNDS(1, n^1).


The TRS R consists of the following rules:

   a__f(f(a)) -> c(f(g(f(a))))
   mark(f(X)) -> a__f(mark(X))
   mark(a) -> a
   mark(c(X)) -> c(X)
   mark(g(X)) -> g(mark(X))
   a__f(X) -> f(X)

S is empty.

(3) CpxTrsMatchBoundsProof (FINISHED)
A linear upper bound on the runtime complexity of the TRS R could be shown with a Match Bound [MATCHBOUNDS1,MATCHBOUNDS2] of 2. 
The certificate found is represented by the following graph.

"[7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18]
{(7,8,[a__f_1|0, mark_1|0, f_1|1, a|1, c_1|1]), (7,9,[c_1|1]), (7,13,[a__f_1|1, f_1|2]), (7,14,[g_1|1]), (7,15,[c_1|2]), (8,8,[f_1|0, a|0, c_1|0, g_1|0]), (9,10,[f_1|1]), (10,11,[g_1|1]), (11,12,[f_1|1]), (12,8,[a|1]), (13,8,[mark_1|1, a|1, c_1|1]), (13,13,[a__f_1|1, f_1|2]), (13,14,[g_1|1]), (13,15,[c_1|2]), (14,8,[mark_1|1, a|1, c_1|1]), (14,13,[a__f_1|1, f_1|2]), (14,14,[g_1|1]), (14,15,[c_1|2]), (15,16,[f_1|2]), (16,17,[g_1|2]), (17,18,[f_1|2]), (18,8,[a|2])}"
