High school junior in Saint Johns, Florida, passionate about engineering, mathematics, and building things that matter.

About

A little about me

I'm a 17 year old teen in Florida. I enjoy working across the intersection of mathematics, software, and engineering.

Outside of school, I contribute to the OEIS, build automated systems, teach math at Mathnasium, and volunteer with local organizations.

I have solved 100+ problems on projecteuler.net - all without external libraries (though I have switched programmming langauges depending on the problem to make things easier).

Currently I am working on starting a bruteforce on a 13k+ digit probable prime. For the software, I am considering Primo, CM-ECPP (www.multiprecision.org), and ECPP-dj. Primo is the obvious choice as it is the fastest. However it only runs on x64 Linux and requires a GUI to operate. I plan to run the bruteforce on a server and the current servers I have access to are not GUI-based VMs. CM-ECPP from multiprecision is the third fastest, however the slowdown in speed is considerable. ECPP-dj is second fastest, however it is not very reputable within the scientific community and was made from a community member of the prime searching community. It is also not maintained anymore. Additionally, the bruteforce will take serveral weeks to months. At the time of writing this, Primo is looking the most viable. - Aidan
