Kruskal’s Algorithm: Cheapest Network Connections

Building the perfect network is actually just about being incredibly greedy. It is called Kruskal’s

Algorithm and it solves a massive logistics problem. Imagine you need to connect power

lines to six different cities. You do not just build random roads. You look at the

map and pick the absolute cheapest connection first. Then the next cheapest. You keep grabbing

the low-hanging fruit. The only rule is that you never create a loop because loops

are a waste of money. You stop once everyone is connected, creating a Minimum Spanning Tree.

It is the mathematical proof that taking the cheap route is sometimes the smartest engineering

decision you can make.
