Get neighbors within radius
neighbors, distances = agent.get_neighbors_in_radius(radius=0.2)
Find k nearest neighbors
nearest, distances = agent.get_nearest_neighbors(k=5)
The new implementation particularly benefits models requiring frequent position updates and neighbor queries, such as flocking simulations or particle systems. See [2584](https://github.com/projectmesa/mesa/pull/2584) for more details. We would love to get feedback on the new Continuous Space in [#2611](https://github.com/projectmesa/mesa/discussions/2611).
Other improvements in this release include consistent visualization behavior across space types with the reimplementation of `draw_voronoi` [2608](https://github.com/projectmesa/mesa/pull/2608), and a new render interval slider for controlling visualization update frequency in SolaraViz, which helps improve performance when working with complex visualizations [#2596](https://github.com/projectmesa/mesa/pull/2596). We've also fixed a bug affecting random number generation determinism when using `Model(seed=something)`, ensuring both `model.random` and `model.rng` now behave consistently when seeded with the same initial value [#2598](https://github.com/projectmesa/mesa/pull/2598).
