simulator

This paper compares three methods for grounding a frozen LLM (Qwen2.5-32B-Instruct) in a wastewater treatment simulator for causal question answering, including live tool-use, structured parameter injection, and a small decoupled retrieval model, achieving high accuracy and cross-plant transfer.

A beginner shares their experience learning to fly FPV drones, using simulators, AI assistance for gear recommendations, and detailing the equipment they purchased.

This article describes a Kelly Criterion simulator that models bankroll evolution across repeated bets, showing how growth, volatility, and drawdowns interact under fixed assumptions. It explains the formula's growth-optimality and its use in betting contexts.

A web version of the Mars MIPS simulator now includes a built-in C compiler, allowing users to write and simulate MIPS assembly and C code in the browser.

Built a hexapod robot simulator using inverse kinematics and gait algorithms written from scratch, with code named Kimi K3.

SPEAR is a Python library that controls Unreal Engine for photorealistic rendering at high speed, providing extensive programmability and unique ground-truth modalities for embodied AI research.

Codex can now be used directly for developing iOS apps, integrating product design, built-in browser prototyping, and simulator preview without needing to open Xcode.

Webernetes is an open-source library from ngrok that simulates Kubernetes clusters in the browser using TypeScript, enabling interactive Kubernetes content without backend infrastructure.

EIBench introduces a simulator-based benchmark for interactive emotion management in LLMs, enabling evaluation and training via per-turn user state feedback. The authors propose CTC-GRPO, a reinforcement learning method that improves emotion management performance across multiple benchmarks.

An interactive web-based simulator of a Nipkow disk mechanical TV, allowing users to experience the full signal chain with real physics controls and a live preview of the Analog TV Simulator app.

An interactive solar-system simulator that models gravitational physics from Newtonian to Einsteinian mechanics.

This paper introduces Mahjax, a fully vectorized Riichi Mahjong simulator implemented in JAX for GPU-accelerated reinforcement learning, achieving high throughput and enabling tabula rasa training.

A token timing simulator widget was added to the LLM Engineer's Almanac, demonstrating the DFlash technique achieving ~1k TPS, to help users viscerally understand benchmark performance numbers.

A web-based system design simulator lets users drag and drop components like API gateways, databases, and caches to simulate real-time traffic and observe latency, bottlenecks, and failures.

An interactive web-based simulator lets users tweak parameters of a fusion power plant and instantly see resulting Q, efficiencies, and power flows.
