non-incremental/FP/20200911-Pine/1599120907623486000.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:
-0.02*x + -0.13*y + 0.54*x^2 + 1.0*x*y + 0.93*y^2 <= 0.02
and
x in [-0.4,0.2]
y in [-0.2,0.4]
