Personally, it’s very rare that I need to reach for a specialized algorithm. I’m not sure if that’s primarily the problem space I work in (services providing user identity and access management), but I never find the need to go beyond a brute force search or need a data structure other than an array or built in hash map (sometimes a concurrent hash map). Most of the optimization I do involves eliminating network calls and implementing caching.
