A C++17 library for automatic differentiation with forward and reverse mode support, enabling efficient derivative computation.
autodiff is a C++ library that implements automatic differentiation algorithms, enabling developers to compute derivatives of mathematical functions efficiently and with minimal code changes. It solves the problem of manually implementing derivative calculations, which is error-prone and time-consuming, especially in fields like machine learning and optimization. The library provides both forward and reverse mode differentiation through simple type replacements in C++ code.
C++ developers working on numerical computing, scientific simulations, machine learning frameworks, or optimization algorithms who need reliable and efficient gradient computations.
Developers choose autodiff for its modern C++17 design, intuitive API that requires minimal code modifications, and support for both forward and reverse mode automatic differentiation, making it a versatile tool for high-performance derivative calculations.

Utilizes advanced C++17 techniques for type-safe and efficient automatic differentiation, ensuring high performance and reliability in numerical computing.
As a header-only library, it can be easily integrated into C++ projects without complex build dependencies, simplifying setup and usage.
Provides both forward and reverse mode automatic differentiation, allowing developers to choose the optimal method based on input-output dimensions, as demonstrated in the README examples.
Minimal code changes are required, such as replacing 'double' with 'dual' or 'var', to enable derivative calculations, maintaining readability and reducing implementation overhead.
Requires a modern C++17 compiler, which may not be available in all development or deployment environments, limiting portability and adoption in legacy systems.
Focuses on differentiable mathematical operations; may not handle arbitrary C++ code, non-differentiable constructs, or complex control flow without manual intervention or extensions.
Reverse mode involves expression tree traversal, which can introduce memory and computational overhead for very simple functions compared to hand-coded derivatives or forward mode.
