Expand description

Metrics computed for a match

Fields§

§error: f64

Absolute error from target

§is_exact: bool

Whether this is an exact match (error < 1e-14)

§complexity: u32

Total complexity score

§ugliness: f64

“Ugliness” penalty (deep nesting, many ops)

§novelty: f64

Novelty score (rarer operators/constants)

§stability: f64

Stability score (Newton conditioning)

§diversity: f64

Operator diversity score

Implementations§

Source §

impl MatchMetrics

Source

pub fn from_match(m: &Match, freq_map: Option<&OperatorFrequency>) -> Self

Compute metrics for a match

Source

pub fn elegant_score(&self) -> f64

Elegant score: lower is better Optimizes for simplicity and cleanliness

Source

pub fn interesting_score(&self, error_cap: f64) -> f64

Interesting score: higher is better Optimizes for novelty while maintaining reasonable error

Source

pub fn stable_score(&self) -> f64

Stable score: higher is better
