(0) CpxIntTrs (1) Loat Proof [FINISHED, 205 ms] (2) BOUNDS(1, INF) ---------------------------------------- (0) Obligation: Complexity Int TRS consisting of the following rules: eval(A, B, C) -> Com_1(eval(A + B, B - 2, C + 1)) :|: A >= 0 eval(A, B, C) -> Com_1(eval(A + C, B, C - 2)) :|: A >= 0 start(A, B, C) -> Com_1(eval(A, B, C)) :|: TRUE The start-symbols are:[start_3] ---------------------------------------- (1) Loat Proof (FINISHED) ### Pre-processing the ITS problem ### Initial linear ITS problem Start location: start 0: eval -> eval : A'=A+B, B'=-2+B, C'=1+C, [ A>=0 ], cost: 1 1: eval -> eval : A'=C+A, C'=-2+C, [ A>=0 ], cost: 1 2: start -> eval : [], cost: 1 ### Simplification by acceleration and chaining ### Accelerating simple loops of location 0. Accelerating the following rules: 0: eval -> eval : A'=A+B, B'=-2+B, C'=1+C, [ A>=0 ], cost: 1 1: eval -> eval : A'=C+A, C'=-2+C, [ A>=0 ], cost: 1 Found no metering function for rule 0. Found no metering function for rule 1. Removing the simple loops:. Accelerated all simple loops using metering functions (where possible): Start location: start 0: eval -> eval : A'=A+B, B'=-2+B, C'=1+C, [ A>=0 ], cost: 1 1: eval -> eval : A'=C+A, C'=-2+C, [ A>=0 ], cost: 1 2: start -> eval : [], cost: 1 Chained accelerated rules (with incoming rules): Start location: start 2: start -> eval : [], cost: 1 3: start -> eval : A'=A+B, B'=-2+B, C'=1+C, [ A>=0 ], cost: 2 4: start -> eval : A'=C+A, C'=-2+C, [ A>=0 ], cost: 2 Removed unreachable locations (and leaf rules with constant cost): Start location: start popout
