Accelerating the following rules: 0: f2 -> f2 : A'=1+A, B'=1+B, C'=-1+C, [], cost: 1 Accelerated rule 0 with NONTERM, yielding the new rule 5. Removing the simple loops: 0. Accelerated all simple loops using metering functions (where possible): Start location: f1 5: f2 -> [3] : [], cost: INF 1: f1 -> f2 : [ A>=C && B>=A && C>=B ], cost: 1 Chained accelerated rules (with incoming rules): Start location: f1 1: f1 -> f2 : [ A>=C && B>=A && C>=B ], cost: 1 6: f1 -> [3] : [ A>=C && B>=A && C>=B ], cost: INF Removed unreachable locations (and leaf rules with constant cost): Start location: f1 6: f1 -> [3] : [ A>=C && B>=A && C>=B ], cost: INF ### Computing asymptotic complexity ### Fully simplified ITS problem Start location: f1 6: f1 -> [3] : [ A>=C && B>=A && C>=B ], cost: INF Computing asymptotic complexity for rule 6 Resulting cost INF has complexity: Nonterm Found new complexity Nonterm.
