(0) CpxIntTrs (1) Loat Proof [FINISHED, 843 ms] (2) BOUNDS(INF, INF) ---------------------------------------- (0) Obligation: Complexity Int TRS consisting of the following rules: f0(A, B) -> Com_1(f1(C, 1)) :|: TRUE f1(A, B) -> Com_1(f1(A - 10, B - 1)) :|: B >= 1 && A >= 101 f1(A, B) -> Com_1(f1(A + 11, B + 1)) :|: B >= 1 && 100 >= A The start-symbols are:[f0_2] ---------------------------------------- (1) Loat Proof (FINISHED) ### Pre-processing the ITS problem ### Initial linear ITS problem Start location: f0 0: f0 -> f1 : A'=free, B'=1, [], cost: 1 1: f1 -> f1 : A'=-10+A, B'=-1+B, [ B>=1 && A>=101 ], cost: 1 2: f1 -> f1 : A'=11+A, B'=1+B, [ B>=1 && 100>=A ], cost: 1 ### Simplification by acceleration and chaining ### Accelerating simple loops of location 1. Accelerating the following rules: 1: f1 -> f1 : A'=-10+A, B'=-1+B, [ B>=1 && A>=101 ], cost: 1 2: f1 -> f1 : A'=11+A, B'=1+B, [ B>=1 && 100>=A ], cost: 1 Accelerated rule 1 with metering function meter (where 10*meter==-100+A) (after adding A<=B), yielding the new rule 3. Accelerated rule 1 with backward acceleration, yielding the new rule 4. Accelerated rule 2 with metering function meter_1 (where 11*meter_1==100-A), yielding the new rule 5. During metering: Instantiating temporary variables by {meter==1} Nested simple loops 2 (outer loop) and 3 (inner loop) with metering function 89+10*meter-A, resulting in the new rules: 6. During metering: Instantiating temporary variables by {k==-1+B} During metering: Instantiating temporary variables by {k==1} Removing the simple loops: 1 2. Accelerated all simple loops using metering functions (where possible): Start location: f0 0: f0 -> f1 : A'=free, B'=1, [], cost: 1 3: f1 -> f1 : A'=-10*meter+A, B'=-meter+B, [ B>=1 && A>=101 && A<=B && 10*meter==-100+A && meter>=1 ], cost: meter 4: f1 -> f1 : A'=A-10*k, B'=-k+B, [ B>=1 && A>=101 && k>0 && 1-k+B>=1 && 10+A-10*k>=101 ], cost: k 5: f1 -> f1 : A'=11*meter_1+A, B'=meter_1+B, [ B>=1 && 100>=A && 11*meter_1==100-A && meter_1>=1 ], cost: meter_1 6: f1 -> f1 : A'=979-10*(89+10*meter-A)*meter+110*meter-10*A, B'=89-(89+10*meter-A)*meter+10*meter-A+B, [ B>=1 && 100>=A && 11+A>=101 && 11+A<=1+B && 10*meter==-89+A && meter>=1 && 89+10*meter-A>=1 ], cost: 89+(89+10*meter-A)*meter+10*meter-A Chained accelerated rules (with incoming rules):
