fix: Ensure correct order of uniform distribution limits

[benjaminhuth]

Pulled out of #3759

Summary by CodeRabbit

• Bug Fixes

  • Enhanced validation for direction generation parameters to ensure they are within acceptable ranges.
  • Adjusted calculations for cosine and eta values to align with the properties of the cosine function.

• Tests

  • Modified random distribution ranges in unit tests for the CylinderVolumeBuilder to improve test coverage and accuracy.

Walkthrough

Changes made to GenerateParameters.hpp enhance the generateBoundDirection function by adding assertions for thetaMin and thetaMax, ensuring they are within valid ranges. The calculations for cosThetaMin, cosThetaMax, etaMin, and etaMax have been reversed to align with the properties of the cosine function. In CylinderVolumeBuilderTests.cpp, adjustments to random distribution ranges in unit tests were made, preserving the overall test structure while altering specific parameters.

Changes

File Path	Change Summary
Core/include/Acts/EventData/detail/GenerateParameters.hpp	Added assertions for thetaMin and thetaMax; reversed calculations for cosThetaMin, cosThetaMax, etaMin, and etaMax.
Tests/UnitTests/Core/Geometry/CylinderVolumeBuilderTests.cpp	Altered ranges of random distributions in several unit tests, maintaining overall test structure.

Possibly related PRs

• refactor: FPE safe eta/theta conversion #3788: The changes in this PR involve modifications to the etaFromTheta and thetaFromEta functions, which are directly related to the adjustments made in the generateBoundDirection function in the main PR, as both involve the handling of theta and eta parameters.

Suggested labels

Component - Core, automerge

In the depths of code, a change was made,
Bound directions refined, no need to be afraid.
With assertions in place, and logic anew,
The tests now dance with distributions true.
A journey of parameters, in harmony they flow,
In the realm of coding, watch the brilliance grow! 🌟

Core/include/Acts/EventData/detail/GenerateParameters.hpp (2)

105-118: Correct, the order of cosine bounds is, hmm!

Wise changes these are! For monotonically decreasing cosine function between [0,π], reversed the bounds we have. Prevent incorrect sampling from uniform distribution, this does. Strong with the Force, these assertions are!

---

121-122: Balanced, the eta calculations now are!

Reversed the eta bounds we have, maintaining harmony with theta they do. Inverse relationship between eta and theta, respected it is!

Tests/UnitTests/Core/Geometry/CylinderVolumeBuilderTests.cpp (1)

25-25: Fixed, the order of distribution bounds is!

In all test cases, corrected the uniform distribution ranges we have. From (-11., -15.) to (-15., -11.) they changed, ensuring valid sampling they do. Follows the ways of mathematics, this does, where lower bound must precede upper bound.

Also applies to: 117-117, 288-288

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>, please review it.
  • Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
  • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.
