Module inanis::tuning::tuner

Structs

• TunerContext
• TunerParameter
• TunerPosition

Functions

• calculate_error 🔒
  Calculates an error by evaluating all loaded positions with the currently set evaluation parameters. Multithreading is supported by threads_count.
• get_array 🔒
  Gets a Rust representation of the piece values array.
• get_header 🔒
  Gets a generated Rust source file header with timestamp and best_error.
• get_parameter 🔒
  Gets a Rust representation of the parameter with the specified name and value.
• get_piece_square_table 🔒
  Gets a Rust representation of the piece-square tables with the specified values.
• load_positions 🔒
  Loads positions from the epd_filename and parses them into a list of TunerPosition. Returns Err with a proper error message if the file couldn’t be parsed.
• load_values 🔒
  Transforms the current evaluation values into a list of TunerParameter. Use lock_material if the parameters related to piece values should be skipped, and random_values if the parameters should have random values (useful when initializing tuner).
• run
  Runs tuner of evaluation parameters. The input file is specified by epd_filename with a list of positions and their expected results, and the output_directory directory is used to store generated Rust sources with the optimized values. Use lock_material to disable tuner for piece values, and random_values to initialize evaluation parameters with random values. Multithreading is supported by threads_count.
• save_values 🔒
  Transforms values into the evaluation parameters, which can be used during real evaluation. Use lock_material if the parameters related to piece values should be skipped.
• save_values_internal 🔒
  Saves index-th evaluation parameter stored in values in the destination.
• save_values_to_i8_array_internal 🔒
  Saves i8 array starting at the index of values in the array.
• save_values_to_i16_array_internal 🔒
  Saves i16 array starting at the index of values in the array.
• validate
  Tests the correctness of load_values and save_values methods.
• write_evaluation_parameters 🔒
  Generates parameters.rs file with current evaluation parameters, and saves it into the output_directory.
• write_piece_square_table 🔒
  Generates piece-square tables (Rust source file with current evaluation parameters), and saves it into the output_directory.
