non-incremental/QF_NRA/20200911-Pine/1599121863820026000.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:
x1' := x1 + 0.01 * x2
x2' := -0.01 * x1 + 0.99 * x2
Input ranges:
x1 in [0.0,1.0]
x2 in [0.0,1.0]
Invariant:
-1.0*x1 + -0.55*x2 + 0.9*x1^2 + 0.45*x1*x2 + 0.98*x2^2 <= 0.9
and
x1 in [-0.6,1.7]
x2 in [-1.0,1.0]
