Inference procedure has parameters:
Ice fuel: 200
Timeout: 60s
Convolution: right


Learning problem is:

env: {
nat -> {s, z}
}
definition:
{

}

properties:
{() -> eq_nat([x, s(x)])}


over-approximation: {}
under-approximation: {}

Clause system for inference is:

{
() -> eq_nat([x, s(x)]) -> 0
}

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