package:osqp

Dart bindings for the OSQP (Operator Splitting Quadratic Program) solver.

OSQP is a numerical optimization package for solving convex quadratic programs. Quadratic programming is a superset of linear programming, so this solver can also handle linear programming problems.

Loads of real world optimisation problems can be formulated as linear or quadratic programming problems. For example, I wrote this package so that I could use OSQP to optimise my home solar panel and battery.

Features

• High-level Dart API: Idiomatic wrappers around OSQP's C API. For example, the C OSQPSolver is wrapped by the Dart Solver, and OSQPCscMatrix is wrapped by Matrix.
• Automatic Memory Management: Memory is freed automatically via NativeFinalizers.
• Cross-Platform Build Hooks: Automated native compilation using Dart build hooks on Linux, MacOS, and Windows (probably works on iOS and Android too, but I haven't tested it).
• Raw FFI Access: You can also use the FFI bindings directly if you need low level access.

Usage

See example/osqp_example.dart for a complete working example. For more information, check out the OSQP documentation.

Building

This package uses Dart build hooks to build the native OSQP C library using CMake. This works automatically, provided you have installed:

• CMake (version 3.18 or newer)
• A C/C++ compiler toolchain (e.g., GCC, Clang, or MSVC)
