(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:

   f(a) -> f(c(a))
   f(c(X)) -> X
   f(c(a)) -> f(d(b))
   f(a) -> f(d(a))
   f(d(X)) -> X
   f(c(b)) -> f(d(a))
   e(g(X)) -> e(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:

   f(a) -> f(c(a))
   f(c(X)) -> X
   f(c(a)) -> f(d(b))
   f(a) -> f(d(a))
   f(d(X)) -> X
   f(c(b)) -> f(d(a))
   e(g(X)) -> e(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 3. 
The certificate found is represented by the following graph.

"[8, 9, 10, 11, 12, 13, 14, 15, 16, 17]
{(8,9,[f_1|0, e_1|0, a|1, c_1|1, d_1|1, b|1, g_1|1, e_1|1, a|2, b|2, b|3]), (8,10,[f_1|1]), (8,12,[f_1|1]), (8,14,[f_1|1]), (8,16,[f_1|2]), (9,9,[a|0, c_1|0, d_1|0, b|0, g_1|0]), (10,11,[c_1|1]), (11,9,[a|1]), (12,13,[d_1|1]), (13,9,[a|1]), (14,15,[d_1|1]), (15,9,[b|1]), (16,17,[d_1|2]), (17,9,[b|2])}"
