Deterministic Simulation GitHub Repositories

A curated list of awesome deterministic simulation testing resources 😎

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

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

renew engine: a deterministic, code-first game engine in Rust. Fixed-timestep simulation in Q47.16 fixed point, Vulkan rendering through ash, and every capability driven from the CLI with schema-versioned JSON. 27 modular crates. Apache-2.0. Early development.

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.

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.

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

Deterministic non-LLM A-Life cosmos on Tsotchke math. v0.23.0 adds race-safe Big Tree fruit/leaf food, a neutral social sanctuary, bounded ecology visits, and removes Xenomimic tether remnants. WebGL2/Three.js; consciousness/quantum metrics are classical proxies.

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

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

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

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