Okay so I was going through $\textbf{Po-Shen Loh's}$ handouts and i saw this pdf called $\textbf{brutal force.}$ Well from what i understand it is basically using induction to prove geometric problems (In a video of youtube where the USA team discusses the IMO 2006 problems, Zuming mentions this technique too).
It seems really nice and interesting however i am having a really hard time trying to find the some handouts/resources that explain this topic well. Po's handout barely mentioned it and then gave questions (which i assume is because it was originally meant for MOP students who are expected to know such stuff i guess?).
So, are there any resources out there which could help me understand this seemingly beautiful but elusivr topic? Thanks a lot.
