Converting to forward existential form...Done !
original formula: (AG((SpA<=Si)) * (!(EG((Si<=Cb))) + AG((MwU>=2))))
=> equivalent forward existential formula: ([(FwdU(Init,TRUE) * !((SpA<=Si)))] = FALSE * [(FwdU((Init * !(!(EG((Si<=Cb))))),TRUE) * !((MwU>=2)))] = FALSE)
Reverse transition relation is NOT exact ! Due to transitions t13, Intersection with reachable at each step enabled. (destroyed/reverse/intersect/total) :0/17/1/18
