This AI just figured out geometry is this a step towards artificial reasoning?
In this episode:
Researchers at Google Deepmind have developed an AI that can solve International Mathematical Olympiad-level geometry problems, something previous AIs have struggled with. They provided the system with a huge number of random mathematical theorems and proofs, which it used to approximate general rules of geometry. The AI then applied these rules to solve the Olympiad problems and show its workings for humans to check. The researchers hope their system shows that it is possible for AIs to \u2018learn\u2019 basic principles from large amounts of data and use them to tackle complex logical challenges, which could prove useful in fields outside mathematics.

Mass Mortality Events, sometimes called mass die-offs, can result in huge numbers of a single species perishing in a short period of time. But there\u2019s not a huge amount known about the effects that events like these might be having on wider ecosystems. Now, a team of researchers have built a model ecosystem to observe the impact of mass die-offs on the delicate balance of populations within it.
