Akreon Convex

Typed convex modeling, conic canonicalization, and primal-dual optimization in C++26.

Start here

• Build, install, and examples
• Architecture: source organization and design.
• Support and roadmap: implemented capabilities and limitations.
• API reference: types and functions.

Workflow

Area	Purpose
Model	Compose fixed-dimension variables, DCP expressions, sets, objectives, and constraints.
Canonicalize	Convert supported compositions into affine constraints and product cones.
Solve	Inspect solver status, primal/dual iterates, numerical events, and diagnostics.

C++ integration

#include <akreon/convex/convex.hpp>

Link the Akreon::Convex CMake target. The library is header-only; dimensions and mathematical contracts are represented in C++ types.

LP, SOCP, and SDP are supported; QP/QCQP support depends on available conic reformulations. Exponential/power cone solving is incomplete.
