non-incremental/QF_NRA/20200911-Pine/1599121982750472000.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) + 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 [-2.8e-07,2.8e-07]
Invariant:
-0.11*u + 1.0*u^2 + 0.04*u*v + 0.1*v^2 <= 1.64
and
u in [-1.3,1.4]
v in [-4.1,4.1]
Query: Loop and Invariant and not Invariant'
