WORST_CASE(INF,?) ### Pre-processing the ITS problem ### Initial linear ITS problem Start location: __init 0: f1_0_main_New -> f176_0_iter_NULL : arg1'=arg1P_1, [ arg1P_1>3 ], cost: 1 1: f176_0_iter_NULL -> f176_0_iter_NULL : arg1'=arg1P_2, [ 1+arg1P_2<=arg1 && arg1>0 && arg1P_2>-1 ], cost: 1 2: __init -> f1_0_main_New : arg1'=arg1P_3, [], cost: 1 Checking for constant complexity: The following rule is satisfiable with cost >= 1, yielding constant complexity: 2: __init -> f1_0_main_New : arg1'=arg1P_3, [], cost: 1 ### Simplification by acceleration and chaining ### Accelerating simple loops of location 1. Accelerating the following rules: 1: f176_0_iter_NULL -> f176_0_iter_NULL : arg1'=arg1P_2, [ 1+arg1P_2<=arg1 && arg1>0 && arg1P_2>-1 ], cost: 1 During metering: Instantiating temporary variables by {arg1P_2==-1+arg1} Accelerated rule 1 with metering function arg1, yielding the new rule 3. Removing the simple loops: 1. Accelerated all simple loops using metering functions (where possible): Start location: __init 0: f1_0_main_New -> f176_0_iter_NULL : arg1'=arg1P_1, [ arg1P_1>3 ], cost: 1 3: f176_0_iter_NULL -> f176_0_iter_NULL : arg1'=0, [ arg1>0 ], cost: arg1 2: __init -> f1_0_main_New : arg1'=arg1P_3, [], cost: 1 Chained accelerated rules (with incoming rules): Start location: __init 0: f1_0_main_New -> f176_0_iter_NULL : arg1'=arg1P_1, [ arg1P_1>3 ], cost: 1 4: f1_0_main_New -> f176_0_iter_NULL : arg1'=0, [ arg1P_1>3 ], cost: 1+arg1P_1 2: __init -> f1_0_main_New : arg1'=arg1P_3, [], cost: 1 Removed unreachable locations (and leaf rules with constant cost): Start location: __init 4: f1_0_main_New -> f176_0_iter_NULL : arg1'=0, [ arg1P_1>3 ], cost: 1+arg1P_1 2: __init -> f1_0_main_New : arg1'=arg1P_3, [], cost: 1 Eliminated locations (on linear paths): Start location: __init 5: __init -> f176_0_iter_NULL : arg1'=0, [ arg1P_1>3 ], cost: 2+arg1P_1 ### Computing asymptotic complexity ### Fully simplified ITS problem Start location: __init 5: __init -> f176_0_iter_NULL : arg1'=0, [ arg1P_1>3 ], cost: 2+arg1P_1 Computing asymptotic complexity for rule 5 Solved the limit problem by the following transformations: Created initial limit problem: -3+arg1P_1 (+/+!), 2+arg1P_1 (+) [not solved] removing all constraints (solved by SMT) resulting limit problem: [solved] applying transformation rule (C) using substitution {arg1P_1==n} resulting limit problem: [solved] Solution: arg1P_1 / n Resulting cost 2+n has complexity: Unbounded Found new complexity Unbounded.
