Oct 1, 2025October 2025 performance summary for cayleypy/cayleypy. Focused on stabilizing the PyTorch dependency policy and validating cross-version compatibility to improve CI reliability and upgrade safety. Key features delivered established PyTorch as a required dependency with standardized version constraints across build configuration and docs, setting a baseline minimum and iteratively refining toward newer releases; stability and compatibility tests were executed across multiple PyTorch versions to inform upgrade strategy. The month also included targeted analysis of test failures observed with non-baseline versions to reproduce and isolate issues, contributing to a more predictable development and testing environment.

Sep 1, 2025September 2025 (2025-09) - Cayleypy project: Focused on improving repository quality and developer experience. Delivered documentation readability improvements for the PermutationGroups class and repository hygiene enhancements. Introduced .gitattributes to hide .gap files from Linguist, improving language detection and reducing noise in project metrics. Minor formatting fix to line length in documentation (commit c9dd9f1f513b78bffaf472b07eb2cf8402983127); .gitattributes addition (commit 95ebdb6b05a136d1042efba756115031d48b19a7). Major bugs fixed: None reported; primary work centered on quality and readability improvements. Overall impact: clearer documentation, faster onboarding, cleaner repo metrics, and improved maintainability. Technologies/skills demonstrated: Git, Markdown documentation, repository hygiene, .gitattributes, Linguist language detection, documentation formatting.

May 1, 2025May 2025 Monthly Summary – cayleypy/cayleypy Key features delivered: - LRX Growth Data Expansion: Added computed growth data for LRX with n=15, updated the growth data CSV, and refreshed related test configuration. Included a minor newline cleanup in the growth CSV. - BFS defaults and docs improvements: Fixed handling when max_layer_size_to_store is None by defaulting to a very large value to enable exploring all layers; added documentation clarity for the max_layer_size_to_store parameter. Major bugs fixed: - max_layer_size_to_store=None handling: Implemented default large value to ensure BFS can explore all layers and clarified behavior in docs. - BFS layer verification: Reverted an earlier change to max_layer_size_to_explore in _verify_layers_fast to restore the correct BFS layer size verification limit. Overall impact and accomplishments: - Expanded data modeling capabilities for LRX with new growth data and reinforced test coverage, enabling more accurate analyses. - Improved BFS robustness and reliability through sensible defaults and correct verification logic, reducing edge-case failures. - Strengthened code quality with clearer documentation and incremental, well-documented commits, supporting maintainability and faster onboarding. Technologies/skills demonstrated: - Python development, CSV handling, test configuration management, and documentation practices. - Clear commit messaging and traceability across feature and bug fixes.
