Enum VariableSelectionType

pub enum VariableSelectionType {
    Vsids,
    VsidsHeap,
    FixedOrder,
    RandomOrder,
    JeroslowWangOneSided,
    JeroslowWangTwoSided,
}

Enum representing different variable selection strategies.

Variants

Vsids

VSIDS (Variable State Independent Decaying Sum) selection strategy.

VsidsHeap

VSIDS with a binary heap for efficient selection.

FixedOrder

Fixed order selection strategy, iterating through variables in a fixed order.

RandomOrder

Random order selection strategy, picking variables in a random order.

JeroslowWangOneSided

Jeroslow-Wang one-sided selection strategy, scoring literals based on clause lengths.

JeroslowWangTwoSided

Jeroslow-Wang two-sided selection strategy, scoring variables based on both polarities.

Implementations

impl VariableSelectionType

pub fn to_impl<L: Literal>( self, num_vars: usize, lits: &[L], clauses: &[impl AsRef<[L]>], ) -> VariableSelectionImpls

Converts the VariableSelectionType into a concrete implementation of VariableSelection.

Trait Implementations

impl Clone for VariableSelectionType

fn clone(&self) -> VariableSelectionType

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for VariableSelectionType

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for VariableSelectionType

fn default() -> VariableSelectionType

Returns the “default value” for a type.

impl Display for VariableSelectionType

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for VariableSelectionType

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for VariableSelectionType

fn cmp(&self, other: &VariableSelectionType) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for VariableSelectionType

fn eq(&self, other: &VariableSelectionType) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for VariableSelectionType

fn partial_cmp(&self, other: &VariableSelectionType) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl ValueEnum for VariableSelectionType

fn value_variants<'a>() -> &'a [Self]

All possible argument values, in display order.

fn to_possible_value<'a>(&self) -> Option<PossibleValue>

The canonical argument value.

fn from_str(input: &str, ignore_case: bool) -> Result<Self, String>

Parse an argument into Self.
