neuroptimiser 1.0.1

A modular and asynchronous framework for neuromorphic optimisation using spike-driven metaheuristics and heuristic-controlled spiking dynamics.

NeurOptimiser

NeurOptimiser is a neuromorphic optimisation framework in which metaheuristic search emerges from asynchronous spiking dynamics. It defines optimisation as a decentralised process executed by interconnected Neuromorphic Heuristic Units (NHUs), each embedding a spiking neuron model and a spike-triggered heuristic rule.

This framework enables fully event-driven, low-power optimisation by integrating spiking computation with local heuristic adaptation. It supports multiple neuron models, perturbation operators, and network topologies.

✨ Key Features

• Modular and extensible architecture using Intel’s Lava.
• Supports linear and Izhikevich neuron dynamics.
• Implements random, fixed, directional, and Differential Evolution operators as spike-triggered perturbations.
• Includes asynchronous neighbourhood management, tensor contraction layers, and greedy selectors.
• Compatible with BBOB (COCO) suite.
• Designed for scalability, reusability, and future deployment on Loihi-class neuromorphic hardware.

📦 Installation

pip install -e .

Ensure you have Python ≥ 3.10 and the Lava-NC environment configured.

You can also clone the repository and install it. Check the Makefile for additional options.

🚀 Example Usage

from neuroptimiser import NeuroOptimiser

neuropt = NeuroOptimiser(
    problem=my_bbob_function,
    dimension=10,
    num_units=30,
    neuron_model="izhikevich",
    spike_operator="de_rand",
    spike_condition="l2"
)

neuropt.run(max_steps=1000)

📊 Benchmarking

Neuroptimiser has been validated over the BBOB suite, showing:

• Competitive convergence versus Random Search
• Consistent results across function types and dimensions
• Linear runtime scaling with number of units and problem size
