Say we go to the bank to cash our paycheck. We ask the teller for the fewest bills and coins as possible. Moments later the teller gives us our money and we leave. Minimum spanning tree (MST). Single source shortest path (SSSP), e.g., Dijkstra’s algorithm. We will explore the main properties, with focus on theoretical foundations. MST:.
