non-incremental/FP/20200911-Pine/1599121889466982000.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].

Loop:
x' := x + 0.01 * (-x + 2*x*x + y*y) + rndx0
y' := y + 0.01 * (-y + y*y) + rndy0
Input ranges:
x in [-0.4,0.3]
y in [-0.4,0.3]
rndx0 in [-1.7e-08,1.7e-08]
rndy0 in [-1.6e-08,1.6e-08]
Invariant:
0.1*x + 0.1*y + 0.98*x^2 + 0.01*x*y + 1.0*y^2 <= 0.24
and
x in [-0.4,0.4]
y in [-0.4,0.3]
