(0) CpxIntTrs (1) Loat Proof [FINISHED, 11 ms] (2) BOUNDS(INF, INF) ---------------------------------------- (0) Obligation: Complexity Int TRS consisting of the following rules: f10(A, B, C, D, E, F) -> Com_1(f4(4, 0, 0, D, E, F)) :|: TRUE f4(A, B, C, D, E, F) -> Com_1(f9(A, B, C, C, C, F)) :|: TRUE f7(A, B, C, D, E, F) -> Com_1(f4(A, 1 + B, G, H, E, G)) :|: TRUE f4(A, B, C, D, E, F) -> Com_1(f4(A, 1 + B, G, H, E, G)) :|: TRUE f6(A, B, C, D, E, F) -> Com_1(f4(A, 1 + B, G, H, E, G)) :|: TRUE The start-symbols are:[f10_6] ---------------------------------------- (1) Loat Proof (FINISHED) ### Pre-processing the ITS problem ### Initial linear ITS problem Start location: f10 0: f10 -> f4 : A'=4, B'=0, C'=0, [], cost: 1 1: f4 -> f9 : D'=C, E'=C, [], cost: 1 3: f4 -> f4 : B'=1+B, C'=free_2, D'=free_3, F'=free_2, [], cost: 1 2: f7 -> f4 : B'=1+B, C'=free, D'=free_1, F'=free, [], cost: 1 4: f6 -> f4 : B'=1+B, C'=free_4, D'=free_5, F'=free_4, [], cost: 1 Checking for constant complexity: The following rule is satisfiable with cost >= 1, yielding constant complexity: 0: f10 -> f4 : A'=4, B'=0, C'=0, [], cost: 1 Removed unreachable and leaf rules: Start location: f10 0: f10 -> f4 : A'=4, B'=0, C'=0, [], cost: 1 3: f4 -> f4 : B'=1+B, C'=free_2, D'=free_3, F'=free_2, [], cost: 1 ### Simplification by acceleration and chaining ### Accelerating simple loops of location 1. Accelerating the following rules: 3: f4 -> f4 : B'=1+B, C'=free_2, D'=free_3, F'=free_2, [], cost: 1 Accelerated rule 3 with NONTERM, yielding the new rule 5. Removing the simple loops: 3. Accelerated all simple loops using metering functions (where possible): Start location: f10 0: f10 -> f4 : A'=4, B'=0, C'=0, [], cost: 1 5: f4 -> [5] : [], cost: NONTERM Chained accelerated rules (with incoming rules): Start location: f10 0: f10 -> f4 : A'=4, B'=0, C'=0, [], cost: 1 6: f10 -> [5] : A'=4, B'=0, C'=0, [], cost: NONTERM Removed unreachable locations (and leaf rules with constant cost): Start location: f10 6: f10 -> [5] : A'=4, B'=0, C'=0, [], cost: NONTERM ### Computing asymptotic complexity ### Fully simplified ITS problem Start location: f10 6: f10 -> [5] : A'=4, B'=0, C'=0, [], cost: NONTERM Computing asymptotic complexity for rule 6 Guard is satisfiable, yielding nontermination Resulting cost NONTERM has complexity: Nonterm Found new complexity Nonterm.
