Ising Model Python Packages

abess

Fast Best-Subset Selection Library

smol

Statistical Mechanics on Lattices

ferrotherm

Thermodynamic computing in pure Rust: energy-based models, block-Gibbs, parallel tempering, thermodynamic linear algebra, stochastic differentiable programs, a variational compiler onto device topologies, and a joules ledger. Zero deps, wasm-clean, verified against exact physics — and it reaches real Ising silicon through the same trait as a CPU.

annealbridge

Optimization middleware for AI agents — describe the problem as JSON, get verified, ranked solutions over MCP, CLI or Python.

qqa

Quasi-Quantum Annealing (QQA): a GPU solver for combinatorial & spin-glass optimisation — PyTorch library + live Streamlit dashboard. ICLR 2025.

isingenerator

A library for creating a database that allows analyzing the energy, magnetization, the number of topological domains and the mean size of the topological domains in a square lattice of spins for a Ising Model of two dimensions using Monte Carlo simulation and Metropolis algorithm.

grins

Gene Regulatory Interaction Network Simulator - GRiNS

qugrid

Quantum computing for power system research — from a MATPOWER case to a quantum algorithm in three lines

sawatabi

Sawatabi is an application framework to develop and run stream-data-oriented Ising applications with quantum annealing.

bqpjson

Utilities for working with bqpjson data

ising-animate

Monte Carlo simulation of the Ising Model using the Metropolis Algorithm

neighbormodels

A tool for building crystal lattice models with distance-dependent neighbor interactions.
