Structuralism, despite its influence, was largely abandoned by the 1960s, replaced by other schools of thought like post-structuralism and various forms of cognitive science.

The complexity class PP, which contains problems solvable by a probabilistic Turing machine with bounded error, is surprisingly powerful; it's even more powerful than NP, meaning some problems in PP are provably harder to solve than those in NP, despite the seeming simplicity of its definition in thelaborate
