---

What Is AlphaEvolve?

AlphaEvolve is a self-improving coding agent that leverages the capabilities of Gemini 2.0 models to solve algorithmic problems in a way that mimics natural selection. This isn’t prompt-in, code-out. Instead, it’s a dynamic system where the agent proposes code candidates, evaluates them, improves upon them, and repeats the process through thousands of iterations.

These aren’t just AI guesses. The candidates are rigorously benchmarked and evolved using performance feedback—selecting the best performers and mutating them to discover even better versions over time.

---

How It Works: Evolution + LLMs

At the core of AlphaEvolve is an elegant idea: combine evolutionary search with LLM-driven reasoning.

1. Initial Code Generation: Gemini 2.0 Pro and Flash models generate a pool of candidate algorithms based on a given problem.

2. Evaluation Loop: These programs are tested using problem-specific benchmarks—such as how well they sort, pack, or schedule items.

3. Evolution: The best-performing algorithms are "bred" through mutation and recombination. The LLMs guide this evolution by proposing tweaks and structural improvements.

4. Iteration: This process continues across generations, yielding progressively better-performing solutions.

It’s a system that improves with experience—just like evolution in nature, only massively accelerated by compute and code.

---

Beating the Benchmarks
