Problem Presentations

Date: 22nd of January of December, 2020
Room: to be defined
Duration: each presentation should be prepared to last around 10 to 12 minutes
(send a PDF of any slides you want to use beforehand until 8h30m of that day )
What to present: give a rough idea of the problem and explain your solution to it, including if possible complexities and any difficulties you had.
You can create auxiliary images, show code, use the board, or any other method you prefer, but the idea is that your colleagues can understand the main points of your solution
