Struct CgpConfig 

pub struct CgpConfig {
    pub lambda: usize,
    pub n_inputs: usize,
    pub rows: usize,
    pub cols: usize,
    pub mutation_rate: Probability,
    pub levels_back: usize,
}

Static configuration for a CartesianGeneticProgramming run.

Fields

lambda: usize

Number of offspring per generation (λ in (1 + λ)).

n_inputs: usize

Number of inputs (independent variables) the program sees.

rows: usize

Number of grid rows.

cols: usize

Number of grid columns.

mutation_rate: Probability

Mutation rate applied to each gene of the integer genome. Valid by construction ([0, 1]).

levels_back: usize

Levels-back parameter: how many previous columns a node can connect to. usize::MAX means “any previous column”.

Implementations

impl CgpConfig

pub const GENES_PER_NODE: usize = 3

Genes per node in the genotype layout: (function_id, input_0, input_1).

pub const OUTPUT_GENES: usize = 1

Number of output genes per program (one index pointing to the node whose value is taken as the program output).

pub fn default_for(n_inputs: usize) -> Self

Sensible defaults: 1-output, 1-row, 30-column grid, mutation rate tuned to flip ~3 genes per genome.

pub fn genome_len(&self) -> usize

Total genome length (nodes × 3 + outputs).

Trait Implementations

impl Clone for CgpConfig

fn clone(&self) -> CgpConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CgpConfig

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

Formats the value using the given formatter.

impl Validate for CgpConfig

fn validate(&self) -> Result<(), ConfigError>

Returns Ok(()) when every invariant holds, or the first ConfigError otherwise.

fn validate_all(&self) -> Result<(), Vec<ConfigError>>

Returns every violated invariant rather than just the first.
