• FIX #282: Fixes a memory leak in the neighborhood generation of integer hyperparameters.

v0.6.0

• ADD #255: An easy interface of Float, Integer, Categorical for creating search spaces. Update documentation
• ADD #243: Add forbidden relations between two hyperparamters
• MAINT #243: Change branch master to main
• FIX #259: Numpy runtime error when rounding
• FIX #247: No longer errors when serliazing spaces with an InCondition
• FIX #219: Hyperparamters correctly active with diamond-or conditions

• Fix #231: Links to the pcs formats.
• Fix #230: Allow Forbidden Clauses with non-numeric values.
• Fix #232: Equality == between hyperparameters now considers default values.
• Fix #221: Normal Hyperparameters should now properly sample from correct distribution in log space
• Fix #221: Fixed boundary problems with integer hyperparameters due to numerical rounding after sampling.
• Maint #221: Categorical Hyperparameters now always have associated probabilities, remaining uniform if non are provided. (Same behaviour)
• Add #222: BetaFloat and BetaInteger hyperparamters, hyperparameters distributed according to a beta distribution.
• Add #241: Implements support for PiBo, you can now embed some prior distribution knowledge into ConfigSpace hyperparameters.
  • See the example here.
  • Hyperparameters now have a pdf(vector: np.ndarray) -> np.ndarray to get the probability density values for the input
  • Hyperparameters now have a get_max_density() -> float to get the greatest value in it's probability distribution function, the probability of the mode of the distriubtion.
  • ConfigurationSpace objects now have a remove_parameter_priors() -> ConfigurationSpace to remove any priors

• Fix #212: Equality (==) on CategoricalHyperparameter objects are now invariant to ordering.
• Add #208: ConfigurationSpace::estimate_size() to get the size of a configuration space without considering constraints.
• Add #210: print(config) is now produces a string representation of a valid python dictionary that is suitable for copy and paste.
• Fix #203: Parser for pcs files now correctly coverts types for forbidden clauses, checking for the validaty as well.
