Inference procedure has parameters:
Ice fuel: 200
Timeout: 60s
Convolution: right
Learning problem is:
env: {
nat -> {s, z}
}
definition:
{
}
properties:
{() -> eq_nat([i, j])}
over-approximation: {}
under-approximation: {}
Clause system for inference is:
{
() -> eq_nat([i, j]) -> 0
}
Solving took 0.020144 seconds.

Teacher's answer:
New clause system:
{
() -> eq_nat([i, j]) -> 3
}
Sat witness: Found: (() -> eq_nat([i, j]), {
i -> z ; j -> s(z)
})
