non-incremental/QF_NRA/20200911-Pine/1599121978725162000.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:
-0.04*u + 0.03*v + 1.0*u^2 + 0.04*u*v + 0.12*v^2 <= 1.41
and
u in [-1.2,1.2]
v in [-3.5,3.3]
