non-incremental/QF_NRA/20200911-Pine/1599122160216860000.smt2

These benchmarks were generated while developing the tool Pine [1], which uses
CVC4/Z3 to check inductiveness of invariants. The work is described in [2].

[2] A.Izycheva, E.Darulova, H.Seidl, SAS'20, "Counterexample- and Simulation-Guided Floating-Point Loop Invariant Synthesis"

 Loop:
   u' := u + 0.01 * v
   v' := v + 0.01 * (-0.5 * v - 9.81 * u)

 Input ranges:
   u in [0.0,0.0]
   v in [2.0,3.0]

 Invariant:
   -0.78*u + 0.05*v + 1.0*u^2 + -0.13*u*v + 0.05*v^2 <= 0.65
 and
   u in [-0.4,1.4]
   v in [-3.9,3.0]
