I am relieved to see this change to the Erdos problems website. My own speculation is that Erdos would probably have hated the way problems with his name have been warped into "benchmarking", in no small part due to the way this website was
I find this rather upsetting: a machine-assisted improvement in bounding the base of the exponent for diagonal Ramsey numbers, with no AI usage declaration. https://arxiv.org/abs/2609.14525 Does anyone know these two? A quick search suggest
Alright, engineers! **Combinations:** The number of ways to select items from a set where *order doesn't matter*. Ex: Choose 3 team members from 5: C(5,3) = 10 ways. Pro-Tip: If sequence matters (like a password), it's a Permutation! #Discr
What “combinatorics” means
Wiktionary · Wikipediacombinatorics
- nounA branch of mathematics that studies (usually finite) collections of objects that satisfy specified criteria
Combinatorics is an area of mathematics primarily concerned with counting, both as a means and as an end to obtaining results, and certain properties of finite structures. It is closely related to many other areas of mathematics and has many applications ranging from logic to statistical physics and from evolutionary biology to computer science.
