Cycle detection in directed graphs, topological sort, Kahn’s algorithm. These are the ones that feel simple until you’re implementing them and something quietly goes wrong. Same idea as BFS: try to ...

Abstract: Addressing the limitations of traditional two-step positioning methods, which suffer from reduced accuracy due to error accumulation in low signal-to-noise ...

Personalized algorithms may quietly sabotage how people learn, nudging them into narrow tunnels of information even when they start with zero prior knowledge. In the study, participants using ...

This article was co-authored with Emma Myer, a student at Washington and Lee University who studies Cognitive/Behavioral Science and Strategic Communication. In today’s digital age, social media has ...

Abstract: Large-scale uniform arrays encounter critical challenges due to dense element arrangements, including excessive hardware, elevated computational complexity, high costs, strong mutual ...

What’s on CS111: The final covers programming basics, data structures, algorithms, recursion, and problem-solving, often through multiple-choice and coding questions. How to prepare: Review lectures ...
