Implement shortest-path algorithm One semester: mean time: 4.2 Asymptotic complexity Lecture 10 CS2110 – Fall 2018 “ Simplicity is a great virtue but it requires hard work to achieve it and education to appreciate it. And to make matters worse: complexity sells better. 1. Recall from last time. 2. We were thinking about a toy store. Everything on the shelves is a “toy”.
