👉 Pin math is a method used to efficiently compute the minimum number of pins required to connect a set of nodes in a network, typically represented as a graph. It works by iteratively connecting the two closest nodes that haven't yet been connected, using a minimum spanning tree approach. At each step, the algorithm identifies two nodes that are closest to each other (based on a predefined distance metric), merges them into a single node, and updates the distances of their neighbors. This process continues until all nodes are connected, resulting in a tree structure where each edge represents the connection between two nodes. The total number of edges (pins) in this tree corresponds to the minimum number of pins needed to fully connect all nodes, making pin math a crucial technique in network optimization and design.
