- Created ThreadPool class for parallel processing - Added DBSCANOptimized class with spatial grid indexing - Implemented UnionFind for connected components - Added grid-based neighbor lookup optimization - Framework ready for parallel core point detection and union-find operations Note: ThreadPool implementation needs refinement for C++ compatibility
- Added ankerl::nanobench for high-precision benchmarking - Created benchmark executable for performance comparison - Benchmarks different data sizes (1k, 10k, 50k, 100k points) - Compares original vs optimized DBSCAN implementations - Tests parameter sensitivity (eps, min_pts) - Includes detailed performance analysis with timing - Measures speedup and cluster count accuracy Note: Some template syntax issues need resolution for full functionality
- build: Build the project with CMake - test: Run unit tests - clean: Clean build artifacts - benchmark: Run performance benchmarks - compile_commands: Generate compile_commands.json for IDEs - format: Format code with clang-format - install: Install the library - docs: Generate documentation - debug/release: Build in different configurations - ci: Full CI pipeline simulation - deps: Check system dependencies - stats: Show project statistics - package: Create release package - help: Show available targets Provides convenient development workflow with proper dependency management
- Switch from Make to Ninja build system for faster builds - Remove unused ThreadPool implementation (not currently used in optimized DBSCAN) - Update CMakeLists.txt with build system notes - Keep optimized DBSCAN framework for future parallel enhancements
