Accelerating the following rules: 1: f61_0_main_GE -> f61_0_main_GE : arg1'=arg1P_2, arg2'=arg2+x7_1, [ x7_1>-1 && arg3>arg2 && arg2>-1 && arg1P_2<=arg1 && arg1>0 && arg1P_2>0 ], cost: 1 Found no metering function for rule 1. Removing the simple loops:. Accelerated all simple loops using metering functions (where possible): Start location: __init 0: f1_0_main_ConstantStackPush -> f61_0_main_GE : arg1'=arg1P_1, arg2'=0, arg3'=arg2, [ arg1P_1<=arg1 && arg2>-1 && arg1>0 && arg1P_1>0 ], cost: 1 1: f61_0_main_GE -> f61_0_main_GE : arg1'=arg1P_2, arg2'=arg2+x7_1, [ x7_1>-1 && arg3>arg2 && arg2>-1 && arg1P_2<=arg1 && arg1>0 && arg1P_2>0 ], cost: 1 2: __init -> f1_0_main_ConstantStackPush : arg1'=arg1P_3, arg2'=arg2P_3, arg3'=arg3P_3, [], cost: 1 Chained accelerated rules (with incoming rules): Start location: __init 0: f1_0_main_ConstantStackPush -> f61_0_main_GE : arg1'=arg1P_1, arg2'=0, arg3'=arg2, [ arg1P_1<=arg1 && arg2>-1 && arg1>0 && arg1P_1>0 ], cost: 1 3: f1_0_main_ConstantStackPush -> f61_0_main_GE : arg1'=arg1P_2, arg2'=x7_1, arg3'=arg2, [ arg1>0 && x7_1>-1 && arg2>0 && arg1P_2>0 && arg1P_2<=arg1 ], cost: 2 2: __init -> f1_0_main_ConstantStackPush : arg1'=arg1P_3, arg2'=arg2P_3, arg3'=arg3P_3, [], cost: 1 Removed unreachable locations (and leaf rules with constant cost): Start location: __init ### Computing asymptotic complexity ### Fully simplified ITS problem Start location: __init Obtained the following overall complexity (w.r.t. the length of the input n): Complexity: Constant Cpx degree: 0 Solved cost: 1 Rule cost: 1 Rule guard: [] WORST_CASE(Omega(1),?)
