One notable example is the “kissing number problem.” This geometric challenge asks how many non-overlapping unit spheres can simultaneously touch a central sphere. In 11 dimensions, AlphaEvolve found a configuration with 593 spheres, breaking the previous record of 592.

These discoveries demonstrate AlphaEvolve’s potential for genuine scientific discovery, extending beyond applied optimization tasks.

AlphaEvolve and the Kissing Number Problem

The kissing number problem is a classic challenge in geometry. It asks how many non-overlapping spheres can simultaneously touch a central sphere of the same size.

The problem has been solved for dimensions 1, 2, 3, 4, 8, and 24. However, the kissing numbers for other dimensions remain unknown.

In 11 dimensions, the best-known solution before AlphaEvolve was 592. AlphaEvolve discovered a configuration with 593 spheres, setting a new lower bound for the kissing number in 11 dimensions.

This discovery highlights AlphaEvolve’s ability to tackle complex mathematical problems and push the boundaries of human knowledge.
