Here's a simple game at which a human can out-fox even the cleverest algorithm.

The INI is celebrating its 30th birthday. What is it and what is it do for maths and mathematicians?

Here's our coverage from the International Congress of Mathematicians 2022, including the Fields Medals and other prizes.

The COVID-19 pandemic has amplified the differences between us. Understanding these inequalities is crucial for this and future pandemics.

There have been accusations that the modelling projecting the course of the pandemic was too pessimistic. Are they justified?

In the given scenario of a large park with no discernable edges this solution would be efficient. The problems start to occur in smaller spaces when boundaries such as walls are present. In these situations there would be a lot of space lost at the edges with hexagonal packing and the conventional square packing is often more efficient. The edge effect becomes less of an issue above about 50 individuals though as the lost space becomes relatively less. So in a wide space with more than 50 people use hexagonal packing. If you're in a room a square arrangement is probably better.
