non-incremental/QF_NRA/20200911-Pine/1599121684188100000.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:
x' := x + 0.01 * (-2*x - 3*y + x*x)
y' := y + 0.01 * (x + y)
Input ranges:
x in [0.0,0.1]
y in [0.0,0.1]
Invariant:
-0.03*x + -0.11*y + 0.33*x^2 + 0.72*x*y + 1.0*y^2 <= 0.01
and
x in [-0.2,0.1]
y in [-0.1,0.2]
