(0) CpxIntTrs (1) Loat Proof [FINISHED, 135 ms] (2) BOUNDS(INF, INF) ---------------------------------------- (0) Obligation: Complexity Int TRS consisting of the following rules: f0(A, B, C) -> Com_1(f1(A, B, C)) :|: TRUE f1(A, B, C) -> Com_1(f1(E, F, B)) :|: A >= 1 && D >= 1 && B >= 0 && B <= 0 The start-symbols are:[f0_3] ---------------------------------------- (1) Loat Proof (FINISHED) ### Pre-processing the ITS problem ### Initial linear ITS problem Start location: f0 0: f0 -> f1 : [], cost: 1 1: f1 -> f1 : A'=free_2, B'=free, C'=B, [ A>=1 && free_1>=1 && B==0 ], cost: 1 Simplified all rules, resulting in: Start location: f0 0: f0 -> f1 : [], cost: 1 1: f1 -> f1 : A'=free_2, B'=free, C'=B, [ A>=1 && B==0 ], cost: 1 ### Simplification by acceleration and chaining ### Accelerating simple loops of location 1. Accelerating the following rules: 1: f1 -> f1 : A'=free_2, B'=free, C'=B, [ A>=1 && B==0 ], cost: 1 Accelerated rule 1 with NONTERM (after strengthening guard), yielding the new rule 2. Removing the simple loops:. Accelerated all simple loops using metering functions (where possible): Start location: f0 0: f0 -> f1 : [], cost: 1 1: f1 -> f1 : A'=free_2, B'=free, C'=B, [ A>=1 && B==0 ], cost: 1 2: f1 -> [2] : [ A>=1 && B==0 && free_2>=1 && free==0 ], cost: INF Chained accelerated rules (with incoming rules): Start location: f0 0: f0 -> f1 : [], cost: 1 3: f0 -> f1 : A'=free_2, B'=free, C'=B, [ A>=1 && B==0 ], cost: 2 4: f0 -> [2] : [ A>=1 && B==0 ], cost: INF Removed unreachable locations (and leaf rules with constant cost): Start location: f0 4: f0 -> [2] : [ A>=1 && B==0 ], cost: INF ### Computing asymptotic complexity ### Fully simplified ITS problem Start location: f0 4: f0 -> [2] : [ A>=1 && B==0 ], cost: INF Computing asymptotic complexity for rule 4 Resulting cost INF has complexity: Nonterm Found new complexity Nonterm. Obtained the following overall complexity (w.r.t. the length of the input n): Complexity: Nonterm Cpx degree: Nonterm Solved cost: INF Rule cost: INF Rule guard: [ A>=1 && B==0 ] NO ---------------------------------------- (2) BOUNDS(INF, INF)
