Sleipnir is a reverse mode autodiff library, interior-point method, and NLP solver DSL for C++23 and Python. The DSL automatically chooses the best solver based on the problem structure.

```cpp
#include <print>

#include <sleipnir/optimization/problem.hpp>

int main() {
  // Find the x, y pair with the largest product for which x + 3y = 36
  slp::Problem<double> problem;

auto x = problem.decision_variable();
  auto y = problem.decision_variable();

problem.maximize(x * y);
  problem.subject_to(x + 3 * y == 36);
  problem.solve();

// x = 18.0, y = 6.0
  std::println("x = {}, y = {}", x.value(), y.value());
}
```

```python
#!/usr/bin/env python

from sleipnir.optimization import Problem

def main():
    # Find the x, y pair with the largest product for which x + 3y = 36
    problem = Problem()

x, y = problem.decision_variable(2)

problem.maximize(x * y)
    problem.subject_to(x + 3 * y == 36)
    problem.solve()

# x = 18.0, y = 6.0
    print(f"x = {x.value()}, y = {y.value()}")

if __name__ == "__main__":
    main()
```

Sleipnir supports easy cross-compilation via CMake toolchain files, provides good performance by default, and contains clean [reference implementations](https://github.com/SleipnirGroup/Sleipnir/tree/main/include/sleipnir/optimization/solver) of various solvers with links to explanatory material.

The C++ API also supports arbitrary scalar types, so users can specify higher precision floating-point types at the cost of speed.

## Install

The following platforms are supported:

* Windows
  * OS: Windows 11
  * Runtime: [Microsoft Visual C++ 2022 redistributable](https://learn.microsoft.com/en-us/cpp/windows/latest-supported-vc-redist?view=msvc-170) from Visual Studio 2022 17.13
* Linux
  * OS: Ubuntu 24.04
  * Runtime: GCC 14 libstdc++ (run `sudo apt install g++-14`)
* macOS
  * OS: macOS 14.5
  * Runtime: Apple Clang 16.0.0 libc++ from Xcode 16.2 (run `xcode-select --install`)

To use Sleipnir within a CMake project, add the following to CMakeLists.txt:
```cmake
include(FetchContent)

FetchContent_Declare(
    Sleipnir
    GIT_REPOSITORY https://github.com/SleipnirGroup/Sleipnir.git
    GIT_TAG main
    EXCLUDE_FROM_ALL
    SYSTEM
)
FetchContent_MakeAvailable(Sleipnir)

target_link_libraries(MyApp PUBLIC Sleipnir::Sleipnir)
```

To use Sleipnir in Python, install `sleipnirgroup-jormungandr` from PyPI:
```bash
pip install sleipnirgroup-jormungandr
```
