Analytic Combinatorics

Big O notation, Big Theta Θ notation and Big Omega Ω notation considered harmful.

Analytic Combinatorics is the new emerging computational complexity metric.

Wow, a retoid that doesn't understand.

are they just bitching about big o to get people to notice them or do they actually have a practical alternative because repeating "analytic combinatorics" over and over again sounds very buzzwordy

o/theta/omega are not indicators of performance, they are classifications of resource cost vs input.
a O(n) can be faster than O(1) despite the implied "lower complexity", since O(1) can be arbitrary large.
