non-incremental/QF_NRA/20200911-Pine/1599121861204394000.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 + -0.32*x2 + 0.87*x1^2 + 0.08*x1*x2 + 0.72*x2^2 <= 0.4
 and
   x1 in [-0.3,1.4]
   x2 in [-0.8,1.0]
