Compiler optimizations

Dead-code elimination

In compiler theory, dead-code elimination (also known as DCE, dead-code removal, dead-code stripping, or dead-code strip) is a compiler optimization to remove code which does not affect the program results. Removing such code has several benefits: it shrinks program size, an important consideration in some contexts, and it allows the running program to avoid executing irrelevant operations, which reduces its running time. It can also enable further optimizations by simplifying program structure. Dead code includes code that can never be executed (unreachable code), and code that only affects dead variables (written to, but never read again), that is, irrelevant to the program. (Wikipedia).

Sports Scheduling Complexities

27 July 2021 - This is my summer submission for the 3Blue1Brown Summer of Math Exposition. I wanted to talk through and quantify some of the complexity around the scheduling of sports teams. I think of scheduling as a function, with inputs (teams, constraints) and outputs (schedules).
