Summary: Google’s DeepMind developed an AI agent called AlphaEvolve, significantly advancing mathematical discoveries and problem-solving capabilities in AI. By utilizing genetic algorithms and large language models, AlphaEvolve has not only increased the lower bound for the kissing number in 11 dimensions but also optimized various practical challenges Google faces. This article explores how AlphaEvolve works, its implications for artificial intelligence, and its potential future applications in science and research.
The Power of AlphaEvolve in Artificial Intelligence
In the realm of mathematics, the ‘kissing number’ concept describes how many spheres can touch another sphere of equal size without overlapping. The problem seems straightforward in lower dimensions, but as dimensions increase, finding solutions becomes complex. Recently, Google’s AlphaEvolve AI contributed to this field by enhancing the lower bound of the kissing number in 11 dimensions from 592 to 593.
This may initially appear as a minor upgrade, especially since the upper bound remains unknown at 868. However, it marks a significant achievement in demonstrating that AI can contribute original findings to mathematics, challenging the narrative that large language models (LLMs) like AlphaEvolve merely replicate existing knowledge.
AI’s Role in Mathematical Advancements
AlphaEvolve tackled various open mathematical challenges spanning different areas like analysis, combinatorics, and geometry. As noted by Matej Balog, a lead researcher at DeepMind, the AI successfully replicated known optimal solutions 75% of the time while also uncovering new optimal solutions in 20% of cases. Every newly discovered solution enhances our understanding of complex mathematical concepts.
In an era dominated by AI, these discoveries are pivotal for researchers and mathematicians alike. For example, AlphaEvolve also developed a new algorithm for matrix multiplication, an operation critical to machine learning and artificial intelligence. This builds upon the foundations established by its predecessor, AlphaTensor, which had already outperformed algorithms dating back to 1969.
DeepMind’s AlphaEvolve made improvements to several practical problems at Google.

Transforming Practical Applications with AI
AlphaEvolve’s impact extends beyond theoretical math; it optimizes real-world issues faced by Google. For instance, it improved data center orchestration efficiency by 1% and contributed to the design of the next Google tensor processing unit, demonstrating the practical utility of AI advancements in organizational settings.
How AlphaEvolve Operates
What makes AlphaEvolve remarkable is its versatility in coding problems. Users begin by providing an initial codebase—a suboptimal solution—and a verification program to evaluate effectiveness. The AI, powered by the Gemini LLM, generates and tests numerous candidate programs. By employing a genetic algorithm, AlphaEvolve naturally selects ‘fittest’ solutions for further optimization, iterating this process to enhance the outputs.

As Balog points out, large language models can transcend their training data, generating genuinely new algorithms and knowledge. The success of AlphaEvolve hints at a future where AI systems could take on an even broader range of scientific inquiries.
The Future of AI in Science
The future directions for AlphaEvolve focus on expanding its application range to natural sciences. DeepMind plans to launch an early access program for academics to harness its capabilities for scientific research. Although applying the model to natural problems may be intricate due to verification challenges, it remains a promising avenue for AI applications in various disciplines.
Moreover, integrating AlphaEvolve with DeepMind’s AI co-scientist project could further enhance its capabilities. This synergy aims to bridge hypothesis generation in natural language with algorithmic optimization, paving the way for significant advancements in artificial intelligence.
A Cautious Outlook on AI Evolution
While the potential for AI advancements like those demonstrated by AlphaEvolve excites many, concerns persist about the implications of self-improving systems. Balog and the DeepMind team assure that their priority remains to foster AI that benefits humanity, emphasizing responsible development practices.
