deterministic-simulation

A curated list of awesome deterministic simulation testing resources 😎

Completion-based I/O for Rust. No runtime, no hidden tasks.

An illustrated multi-agent village strategy game. Set objectives; residents gather, build, upgrade and recruit. Battle, inspect decisions and test AI agents. No API key required.

A blank-slate, memory-safe, ultra-high-performance property-graph database in Rust — unified MVCC/time-travel/branches/replication over a fountain-coded commit stream, WCO+factorized execution, incremental everything, and deterministic auditable results.

renew engine: an AI-first game engine in Rust, built to be operated. Bit-deterministic fixed-timestep simulation in Q47.16 fixed point, Vulkan rendering through ash, and every capability driven from the CLI with schema-versioned JSON. 29 modular crates, desktop and mobile. Apache-2.0. Early development.

Fork decisions into living simulations with 1,000 personalities. Watch alternate realities diverge and explore second-order effects.

Deterministic GGPO-style rollback netcode for Unreal Engine 5: fixed-step simulation, SaveGame-reflection state capture, UDP transport with input redundancy and reliable ACKs. MIT-licensed.

Deterministic AI simulation and diagnostics lab for Project Nova / HASHKRIEG — branch-independent matches, replays, metrics, movement tests, combat analysis and comparisons.

Plugging into async/await in .NET for the deterministic simulation of the application logic

An experimental artificial life platform for embodied synthetic cognition and procedural morphogenesis, from individual beings to worlds across scales. Combines adaptive minds, computational physics and simulated quantum systems with expressive 3D forms, live inspection and causal experiments.

A modern, open-source reimplementation of the Cultures game series

Echo is a WARP optic runtime for witnessed causal history, Continuum-compatible suffixes, bounded observation, and holographic readings.

Replay-verified Touhou 6 gameplay semantics for zero-knowledge execution

Raft consensus in pure Python with a deterministic fault-injection simulator and a linearizability checker

Universal game server probe, config management, and administration via Gossamer + VeriSimDB

6X strategy board game exploring economic systems, planetary boundaries, and post-scarcity futures

Deterministic background jobs for .NET with simple methods that leverage source generators for no runtime reflection. Includes a dashboard UI for managing jobs, queues, failures, and schedules.

Deterministic simulation-to-telemetry framework in Rust: model systems, orchestrate runs, stream time-series data, and replay reproducible experiments.

Echtzeitstrategiespiel in der Command-&-Conquer-Tradition. Unity 6 + C#, deterministischer Unity-freier Simulationskern, offene Entwicklung. Arbeitstitel in Umstellung: Hashkrieg.

A deterministic simulation and model testing toolkit for MoonBit with virtual time, seeded randomness, trace/replay, metrics, scenarios, and reusable model tests.
