Enum Or 

pub enum Or {
    Max,
    Probsum,
    Bounded,
}

How OR joins two degrees, in a rule and between rules with the same then.

Variants

Max

The larger: the strongest reason decides, and repeating one doesn’t raise it.

Probsum

a + b − ab: reasons reinforce each other. A reason written twice counts twice (0.6 becomes 0.84), so it suits distinct pieces of evidence, not restatements of one.

Bounded

min(1, a + b): reasons add up, to at most 1. For levels or options of one question, which exclude each other, this is their probabilities’ sum: the chance that one of them holds.
