AlphaEvolve: How our Gemini-powered coding agent is scaling impact across fields
DeepMind published a blog post detailing the real-world impact of AlphaEvolve, a Gemini-powered coding agent designed to discover and optimize algorithms. The post covers applications spanning business operations, infrastructure, and scientific research. AlphaEvolve represents a deployment of LLM-driven evolutionary algorithm search at scale across multiple domains.
AlphaEvolve: A Gemini-powered coding agent for designing advanced algorithms
DeepMind has announced AlphaEvolve, a coding agent powered by Gemini that autonomously evolves algorithms for mathematical and practical computing applications. The system combines large language model creativity with automated evaluators to iteratively improve algorithmic solutions. It represents a significant step in AI-driven algorithm discovery, extending DeepMind's prior work in this space (e.g., AlphaTensor, FunSearch). The announcement comes from DeepMind's official blog, indicating a substantive capability release rather than a research preview.
Researchers at UT-Austin and Google Model Human Decision-Making in Rock-Paper-Scissors
Researchers from UT-Austin and Google used AlphaEvolve, an evolutionary code-optimization method, to synthesize interpretable Python programs that predict move-by-move decisions of LLMs and humans playing rock-paper-scissors against bots. They found that Gemini 2.5 Pro, Gemini 2.5 Flash, and GPT-4.1 share similar sequential-pattern-tracking strategies that are more systematic than typical human play, while GPT-OSS 120B and humans relied on simpler opponent-move-frequency heuristics. The study demonstrates that code synthesis from behavioral data can serve as an interpretability tool for LLM decision-making, revealing that LLMs do not simply mimic human strategies.
Persona Generators: Evolutionary LLM Method for Diverse Synthetic Human Personas
Google researchers Davide Paglieri, Logan Cross, and colleagues propose Persona Generators, a system that uses the AlphaEvolve evolutionary algorithm to generate code that produces 25 diverse persona prompts covering a broad range of attitudes and opinions. The method iteratively optimizes persona prompt diversity using six metrics, outperforming Nemotron Personas (82% vs 76% coverage of possible responses) and a Concordia memory-based baseline (46%). The system uses Gemini 2.5 Pro for questionnaire generation and Gemma 3-27B-IT for persona simulation via the Concordia agent library. The approach reframes persona generation as a coverage optimization problem rather than a data-matching one, enabling more representative synthetic user populations for product research.
Vector Policy Optimization: Training for Diversity Improves Test-Time Search
Vector Policy Optimization (VPO) is a new RL post-training algorithm for LLMs that replaces the scalar reward paradigm with vector-valued rewards, explicitly training models to produce diverse solution sets that specialize across different reward trade-offs. VPO is designed as a near-drop-in replacement for the GRPO advantage estimator and targets inference-scaling search procedures like AlphaEvolve. Across four tasks, VPO matches or outperforms scalar RL baselines on pass@k and best@k metrics, with advantages growing as search budget increases, and unlocks evolutionary search problems that GRPO-trained models cannot solve. The paper argues that diversity-optimized post-training may need to become the default as inference-time search becomes standard.
MLEvolve: Self-evolving multi-agent framework for automated ML algorithm discovery
MLEvolve is a new LLM-based multi-agent framework for end-to-end machine learning algorithm discovery, addressing limitations of existing MLE agents including information isolation and memoryless search. The system introduces Progressive MCGS (a graph-extended tree search), Retrospective Memory for experience accumulation, and decoupled strategic planning from code generation. Evaluated on MLE-Bench, it achieves state-of-the-art medal and valid submission rates within a 12-hour budget, and also outperforms AlphaEvolve on mathematical algorithm optimization tasks.
Google's Aletheia agent uses Gemini 3 Deep Think to generate novel solutions to unsolved Erdős problems
Google researchers introduced Aletheia, an agentic workflow using Gemini 3 Deep Think that generates, verifies, and revises solutions to previously unsolved mathematical problems. Applied to Erdős problems, Aletheia produced 13 correct solutions out of 200 evaluated, with 4 being genuinely novel contributions not found in existing literature. The announcement also reveals Gemini 3 Deep Think's benchmark performance: 48.4% on HLE, 84.6% on ARC-AGI-2, and 93.8% on GPQA Diamond. The system demonstrates both the promise and current limitations of AI-assisted mathematical research, with a 6.5% correct-under-intended-interpretation rate on a hard problem set.
