non-incremental/FP/20200911-Pine/1599121909161127000.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 + rndu0
   v' := v + 0.01 * (-0.5 * v - 9.81 * (u - (u*u*u)/6.0 + (u*u*u*u*u)/120.0)) + rndv0

 Input ranges:
   u in [0.0,0.0]
   v in [2.0,3.0]
   rndu0 in [-6.4e-08,6.4e-08]
   rndv0 in [-1.8e-07,1.8e-07]

 Invariant:
   -0.14*u + 1.0*u^2 + 0.03*u*v + 0.12*v^2 <= 1.49
 and
   u in [-1.2,1.3]
   v in [-3.6,3.5]
