Starting structural reductions in SI_LTL mode, iteration 0 : 1000/1000 places, 4300/4300 transitions.
Drop transitions (Trivial Post-Agglo cleanup.) removed 10 transitions
Trivial Post-agglo rules discarded 10 transitions
Performed 10 trivial Post agglomeration. Transition count delta: 10
Iterating post reduction 0 with 10 rules applied. Total rules applied 10 place count 1000 transition count 4290
Reduce places removed 10 places and 0 transitions.
Iterating post reduction 1 with 10 rules applied. Total rules applied 20 place count 990 transition count 4290
Performed 309 Pre agglomeration using Quasi-Persistent + Divergent Free condition..
Pre-agglomeration after 2 with 309 Pre rules applied. Total rules applied 20 place count 990 transition count 3981
Deduced a syphon composed of 309 places in 6 ms
Reduce places removed 309 places and 0 transitions.
Iterating global reduction 2 with 618 rules applied. Total rules applied 638 place count 681 transition count 3981
Performed 90 Post agglomeration using F-continuation condition.Transition count delta: 90
Deduced a syphon composed of 90 places in 6 ms
Reduce places removed 90 places and 0 transitions.
Iterating global reduction 2 with 180 rules applied. Total rules applied 818 place count 591 transition count 3891
Applied a total of 818 rules in 334 ms. Remains 591 /1000 variables (removed 409) and now considering 3891/4300 (removed 409) transitions.

Support contains 1 out of 1000 places. Attempting structural reductions.
Starting structural reductions in SI_LTL mode, iteration 0 : 1000/1000 places, 4300/4300 transitions.
Drop transitions (Trivial Post-Agglo cleanup.) removed 10 transitions
Trivial Post-agglo rules discarded 10 transitions
Performed 10 trivial Post agglomeration. Transition count delta: 10
Iterating post reduction 0 with 10 rules applied. Total rules applied 10 place count 1000 transition count 4290
Reduce places removed 10 places and 0 transitions.
Iterating post reduction 1 with 10 rules applied. Total rules applied 20 place count 990 transition count 4290
Performed 309 Pre agglomeration using Quasi-Persistent + Divergent Free condition..
Pre-agglomeration after 2 with 309 Pre rules applied. Total rules applied 20 place count 990 transition count 3981
Deduced a syphon composed of 309 places in 4 ms
Reduce places removed 309 places and 0 transitions.
Iterating global reduction 2 with 618 rules applied. Total rules applied 638 place count 681 transition count 3981
Performed 90 Post agglomeration using F-continuation condition.Transition count delta: 90
Deduced a syphon composed of 90 places in 3 ms
Reduce places removed 90 places and 0 transitions.
Iterating global reduction 2 with 180 rules applied. Total rules applied 818 place count 591 transition count 3891
Applied a total of 818 rules in 330 ms. Remains 591 /1000 variables (removed 409) and now considering 3891/4300 (removed 409) transitions.
