Pseudo-Boolean function 𝔹ⁿ → ℝ

Required Associated Types§

Source

type Number: NumberBase

The number type used for the functions’ target set.

Required Methods§

Source

fn new_var<'id>(manager: &mut Self::Manager<'id>) -> AllocResult<Self>

Get a fresh variable, i.e. a function that is 1 if the variable is true and 0 otherwise. This adds a new level to a decision diagram.

Source

fn constant_edge<'id>( manager: &Self::Manager<'id>, value: Self::Number, ) -> AllocResult<EdgeOfFunc<'id, Self>>

Get the constant value, edge version

Source

fn add_edge<'id>( manager: &Self::Manager<'id>, lhs: &EdgeOfFunc<'id, Self>, rhs: &EdgeOfFunc<'id, Self>, ) -> AllocResult<EdgeOfFunc<'id, Self>>

Point-wise addition self + rhs, edge version

Source

fn sub_edge<'id>( manager: &Self::Manager<'id>, lhs: &EdgeOfFunc<'id, Self>, rhs: &EdgeOfFunc<'id, Self>, ) -> AllocResult<EdgeOfFunc<'id, Self>>

Point-wise subtraction self - rhs, edge version

Source

fn mul_edge<'id>( manager: &Self::Manager<'id>, lhs: &EdgeOfFunc<'id, Self>, rhs: &EdgeOfFunc<'id, Self>, ) -> AllocResult<EdgeOfFunc<'id, Self>>

Point-wise multiplication self * rhs, edge version

Source

fn div_edge<'id>( manager: &Self::Manager<'id>, lhs: &EdgeOfFunc<'id, Self>, rhs: &EdgeOfFunc<'id, Self>, ) -> AllocResult<EdgeOfFunc<'id, Self>>

Point-wise division self / rhs, edge version

Source

fn min_edge<'id>( manager: &Self::Manager<'id>, lhs: &EdgeOfFunc<'id, Self>, rhs: &EdgeOfFunc<'id, Self>, ) -> AllocResult<EdgeOfFunc<'id, Self>>

Point-wise minimum min(self, rhs), edge version

Source

fn max_edge<'id>( manager: &Self::Manager<'id>, lhs: &EdgeOfFunc<'id, Self>, rhs: &EdgeOfFunc<'id, Self>, ) -> AllocResult<EdgeOfFunc<'id, Self>>

Point-wise maximum max(self, rhs), edge version

Provided Methods§

Source

fn constant<'id>( manager: &Self::Manager<'id>, value: Self::Number, ) -> AllocResult<Self>

Get the constant value
