non-incremental/QF_NRA/20200911-Pine/1599121901058720000.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 - (u*u*u)/6.0 + (u*u*u*u*u)/120.0))
Input ranges:
u in [0.0,0.0]
v in [2.0,3.0]
Invariant:
-0.17*u + -0.02*v + 1.0*u^2 + 0.03*u*v + 0.1*v^2 <= 0.93
and
u in [-0.9,1.1]
v in [-3.0,3.1]
Query: Loop and Invariant and not Invariant'
