I want to improve my math skills, and looking for some resources primary focused on competitive math. Also any general advices are welcome.
I have an engineering and cs background.
What specific level have you already achieved? Are you looking for optimizations, manifolds or something else?
Back in school I studied calculus, algebra, complex analysis, optimization, probability. Plus I completed courses on algorithms and physics.
I was more interested in math engineering application, but now I feel that I want to expand my knowledge.
I wanted to start with combinatorial optimization as it connected to what I’m working now on and maybe to read something about manifolds. But not limited to.
Also any advices about how to study math if you don’t have an upcoming exam are welcomed.
