Update: Enhanced Randomization Logic with _enable_randomization_type

Overview

This update introduces a more robust and explicit control for parameter randomization using the _enable_randomization_type flag. This addition ensures clear, deliberate activation of advanced randomization types such as symmetric, asymmetric, logarithmic, and exponential.

Previously, randomization could unintentionally apply if _rand flags were enabled and randomization types existed in the configuration. This could cause unintended blending of randomization methods without an explicit on/off control.

Installation

  • Download and replace the simple_kes.py file
  • Download and update/replace the default_config file adding the new configuration options.

Key Changes

  • ✅ Added *_enable_randomization_type flag for each parameter to explicitly control whether randomization types are applied.
  • ✅ Updated get_random_or_default and related randomization methods to enforce the requirement that the randomization type is only active if *_enable_randomization_type is True.
  • ✅ Improved config validation to auto-correct missing randomization keys and ensure base values and randomization percentages are present.
  • ✅ Ensured safer default fallbacks when randomization flags or randomization types are not properly defined.

How It Works Now

Each randomizable parameter now requires:

  • *_rand: Enables min-max randomization.
  • *_enable_randomization_type: Enables type-based randomization (symmetric, asymmetric, logarithmic, exponential).
  • *_randomization_type: Specifies the randomization style.
  • *_randomization_percent: Controls the degree of randomization.

Example:

rho_rand: true
rho_rand_min: 6.0
rho_rand_max: 10.0
rho_enable_randomization_type: true
rho_randomization_type: asymmetric
rho_randomization_percent: 0.2

In this example:

  • Min-max randomization is applied first.
  • Then, an asymmetric randomization layer is applied only because rho_enable_randomization_type is set to true.

Why This Change?

  • 🔒 Explicit Control: Prevents accidental randomization when users may only want min-max behavior.
  • 🛠️ Safer Configs: Forces a deliberate activation of complex randomization methods.
  • 📜 Cleaner Logs: Makes it easier to track which randomization steps were actually applied.
  • ⚙️ Config Flexibility: Allows for fine-tuning of which parameters should have advanced randomization versus simple min-max randomization.

Compatibility

These changes are backward compatible if you add the new _enable_randomization_type keys to your existing configs. If missing, the system safely defaults to treating advanced randomization as disabled. Just ensure you download the new main simple_kes.py file and replace your current version with it.

Recommendation

Review your existing configs and ensure:

  • You add *_enable_randomization_type: true if you want randomization types to be active.
  • You test with the new system to confirm expected behavior.
