Stochas

stochas: Smart Data Orchestration

PyPI version Python versions Tests & Release Status Coverage Ruff Pydantic v2 License Documentation GitHub Discussions PyPI Downloads

stochas is a Python framework built to handle the complexity of Monte Carlo simulations, parametric studies, and probabilistic modeling.

It provides a robust bridge between abstract statistical rules and concrete simulation data, ensuring your experiments are repeatable, traceable, and easy to manage.


Installation

Install the package via your preferred manager:

uv add stochas

or with pip:

pip install stochas

Core Features

  • Salted Seeding: Combines Global Seeds, Parameter Names, and Trial Numbers for unique but deterministic draws.
  • Numeric Mixins: Use your data containers directly in math operations (container * 5.0) without manually extracting values.
  • Nominal Support: Easily toggle between "Perfect World" (Trial 0) and "Probabilistic World" (Monte Carlo) results.
  • Pydantic Foundation: Every component is a Pydantic model, providing out-of-the-box validation and effortless JSON serialization.
  • Unit System: Declare SI, IPS, FPS, or a custom unit system once and tag distributions with unit=u.inch, sampling paths convert values automatically so your input data stays in familiar units while the simulation receives physically consistent numbers.

Why use stochas?

Managing hundreds of simulation trials can quickly become a mess of manual seeds and inconsistent data. stochas solves this by providing:

  • Repeatable Randomness: Our "Salted Seed" logic ensures that any specific trial can be perfectly recreated, even years later, by tying randomness to simple to set and store values.
  • Smart Containers: NamedValue objects behave like numbers or arrays but protect your data from accidental overwrites using a state-machine logic.
  • Physics-Ready Distributions: A wide range of built-in distributions (Normal, Truncated Normal, Log-Normal, etc.) that handle their own random number generators internally.
  • Automatic Unit Conversion: Attach a UnitDescriptor to any distribution or design variable and let StochasBase multiply the conversion factor at sampling time (without manual scaling in generator code).
  • Serialized Registries: Automatically track exactly which "rules" (Distributions) and "results" (NamedValues) were used in every trial for easy export to JSON or databases.
