Crate optimal_pbil

Population-based incremental learning (PBIL).

Examples

use optimal_pbil::*;

println!(
    "{:?}",
    UntilProbabilitiesConvergedConfig::default()
        .start(Config::start_default_for(16, |point| point.iter().filter(|x| **x).count()))
        .argmin()
);

Structs

• AdjustRate
  Degree to adjust probabilities towards best point during steps.
• AdjustRateFromStrError
  Error returned when failing to convert from a string or into ‘AdjustRate’.
• Config
  PBIL configuration parameters.
• InvalidNumSamplesError
  Error returned when ‘NumSamples’ is given a value below lower bound.
• MismatchedLengthError
  Error returned when problem length does not match state length.
• MutationAdjustRate
  Degree to adjust probability towards random value when mutating.
• MutationAdjustRateFromStrError
  Error returned when failing to convert from a string or into ‘MutationAdjustRate’.
• MutationChance
  Probability for each probability to mutate, independently.
• MutationChanceFromStrError
  Error returned when failing to convert from a string or into ‘MutationChance’.
• NumSamples
  Number of samples generated during steps.
• NumSamplesFromStrError
  Error returned when failing to convert from a string or into ‘NumSamples’.
• Pbil
