quip-solver-core

This repository is the shared Quip solver contract. A solver binary accepts Ising problems and returns spin configurations with their energies.

The contract has two bindings. One is a Rust crate workspace. The other is a Python wheel named quip-solver-core. The wheel carries the consensus primitives and the generated gRPC stubs, not the session loop, so a Python solver written today writes its own state machine. A Rust solver conforms today by supplying a Sampler and calling run.

The full contract is in SPEC.md. CHANGELOG.md lists the 0.0.2-rc1 changes. MIGRATING.md covers the move from quip-miner-core.

Crates

Install

Every binding ships from its own registry. The C library ships as a release artifact, because a C consumer wants the compiled object and the header.

Rust

[dependencies]
quip-solver-core = "0.0.2-rc1"

[dev-dependencies]
quip-solver-conformance = "0.0.2-rc1"

One dependency is enough. quip-solver-core re-exports quip_proto and quip_protocol, so the consensus scorer is at quip_solver_core::quip_protocol::scoring::energy_milli.

Python

pip install quip-solver-core

JavaScript and TypeScript

npm install @quip.network/quip-solver-core@rc

C and C++

Download quip-solver-clib-<tag>-linux-amd64.tar.gz from the release page. It holds libquip_solver_c.so, libquip_solver_c.a, and include/quip_solver.h.

Samples

examples/ holds a conformant mock solver in four languages. Rust, C++, Python, and TypeScript each consume the published artifact and pass quip-solver-drive. Start there rather than from this README.

Conformance

A solver is conformant when quip-solver-drive reports a conformant session.

cargo build -p quip-solver-conformance --bin quip-solver-drive --release
./target/release/quip-solver-drive <solver-binary> unix:///tmp/quip-check.sock

Exit code 0 means conformant. The driver spawns any executable, so this works for a solver in any language.
