Overview
Description: Core engine utility functions providing sorting algorithms, error handling, memory management, and miscellaneous math operations.
Context: MuJoCo's engine utilities form the foundational infrastructure layer upon which all other engine subsystems are built. These utilities provide consistent error reporting, safe memory allocation, efficient sorting, and commonly needed mathematical helpers.
Theoretical Basis
Engine utilities follow the principle of separation of concerns by isolating cross-cutting infrastructure from domain-specific physics code. Error handling uses a callback mechanism that allows the host application to intercept and process warnings and errors. Memory management includes both standard heap allocation with error checking and arena-based allocation for temporary per-step buffers. Sorting utilities provide optimized implementations for common patterns such as sorting indices by value, which is used extensively in collision detection and constraint ordering.
