Chalcogenide Memristor Reservoir

Physical reservoir computing substrate for tardigrade_agent

Overview

A chalcogenide memristor array used as a physical reservoir computing substrate, feeding into the tardigrade_agent PPO + Clifford geometric-algebra control stack. The reservoir supplies nonlinear temporal dynamics in hardware rather than simulating them, reducing the compute load carried by the software side of the agent.

Architecture

• Chalcogenide memristor crossbar array as the physical reservoir
• Read/write interface exposing reservoir state to the PPO training loop
• Clifford geometric-algebra layer sitting between reservoir output and the policy network
• Integration point with tardigrade_agent for BOUT++ plasma control tasks

Open questions

• Device-to-device variability characterization across the array
• Long-term drift compensation for the memristor states
• Formal comparison of reservoir-in-hardware vs. simulated-reservoir performance
