Enum ConstructionType 

pub enum ConstructionType {
    FirstFit,
    BestFit,
}

Type of construction heuristic to use.

Construction heuristics build an initial solution by assigning values to uninitialized planning variables. The type determines how values are selected:

• FirstFit: Fast, takes first valid value
• BestFit: Slower, evaluates all options to find best

Examples

use solverforge_solver::manager::ConstructionType;

// First fit - faster but may produce lower quality initial solution
let fast = ConstructionType::FirstFit;
assert_eq!(fast, ConstructionType::default());

// Best fit - slower but produces better initial solution
let best = ConstructionType::BestFit;

Variants

FirstFit

First fit: accept first valid assignment.

Assigns the first value that produces a feasible solution. Fast but may not produce an optimal initial solution.

Example

use solverforge_solver::manager::ConstructionType;

let construction = ConstructionType::FirstFit;

BestFit

Best fit: evaluate all options, pick best score.

Evaluates all possible values and selects the one that produces the best score. Slower but produces a higher quality initial solution.

Example

use solverforge_solver::manager::ConstructionType;

let construction = ConstructionType::BestFit;

Trait Implementations

impl Clone for ConstructionType

fn clone(&self) -> ConstructionType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ConstructionType

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

Formats the value using the given formatter.

impl Default for ConstructionType

fn default() -> ConstructionType

Returns the “default value” for a type.

impl PartialEq for ConstructionType

fn eq(&self, other: &ConstructionType) -> 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.
