Rewrite Strategy: PARALLEL_INNERMOST ---------------------------------------- (3) 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 2. The compatible tree automaton used to show the Match-Boundedness (for constructor-based start-terms) is represented by: final states : [1, 2, 3] transitions: Leaf0(0) -> 0 cons_x0(0) -> 0 Node0(0, 0) -> 0 comp_f_g0(0, 0) -> 0 Cons0(0, 0) -> 0 Nil0() -> 0 walk#10(0) -> 1 comp_f_g#10(0, 0, 0) -> 2 main0(0) -> 3 cons_x1(0) -> 1 walk#11(0) -> 4 walk#11(0) -> 5 comp_f_g1(4, 5) -> 1 comp_f_g#11(0, 0, 0) -> 6 comp_f_g#11(0, 0, 6) -> 2 Cons1(0, 0) -> 7 comp_f_g#11(0, 0, 7) -> 2 comp_f_g#11(0, 0, 0) -> 8 Cons1(0, 8) -> 2 Cons1(0, 0) -> 9 Cons1(0, 9) -> 2 Nil1() -> 10 Cons1(0, 10) -> 3 walk#11(0) -> 11 walk#11(0) -> 12 Nil1() -> 13 comp_f_g#11(11, 12, 13) -> 3 cons_x1(0) -> 4 cons_x1(0) -> 5 cons_x1(0) -> 11 cons_x1(0) -> 12 comp_f_g1(4, 5) -> 4 comp_f_g1(4, 5) -> 5 comp_f_g1(4, 5) -> 11 comp_f_g1(4, 5) -> 12 comp_f_g#11(0, 0, 6) -> 6 comp_f_g#11(0, 0, 7) -> 6 comp_f_g#11(0, 0, 6) -> 8 Cons1(0, 6) -> 7 Cons1(0, 7) -> 7 comp_f_g#11(0, 0, 7) -> 8 Cons1(0, 8) -> 6 Cons1(0, 8) -> 8 Cons1(0, 6) -> 9 Cons1(0, 7) -> 9 Cons1(0, 9) -> 6 Cons1(0, 9) -> 8 comp_f_g#12(4, 5, 13) -> 14 comp_f_g#12(4, 5, 14) -> 3 Cons2(0, 13) -> 15 comp_f_g#12(4, 5, 15) -> 3 comp_f_g#12(4, 5, 13) -> 16 Cons2(0, 16) -> 3 Cons2(0, 13) -> 17 Cons2(0, 17) -> 3 comp_f_g#12(4, 5, 14) -> 14 comp_f_g#12(4, 5, 15) -> 14 comp_f_g#12(4, 5, 14) -> 16 Cons2(0, 14) -> 15 Cons2(0, 15) -> 15 comp_f_g#12(4, 5, 15) -> 16 Cons2(0, 16) -> 14 Cons2(0, 16) -> 16 Cons2(0, 14) -> 17 Cons2(0, 15) -> 17 Cons2(0, 17) -> 14 Cons2(0, 17) -> 16 ---------------------------------------- (4) BOUNDS(1, n^1)
