Key Concepts

Hamiltonian Cycle

A Hamiltonian cycle is a route in a graph that visits each vertex exactly once and returns to the starting vertex. Identifying such a cycle with the minimum total weight is central to solving the TSP problem.

Traveling Salesman Problem (TSP)

The Traveling Salesman Problem is a well-known optimization challenge where the goal is to find the least costly route that visits every vertex exactly once and returns to the starting point. It is a classic NP-hard problem in computational complexity.

Weighted Graph

A weighted graph is a type of graph where each edge is assigned a weight, representing a cost, such as the airfare between cities. This allows for the evaluation of routes based on total accumulated weights.

Graph Theory

Graph theory is the field of mathematics that studies graphs, which are structures used to model pairwise relations between objects. In the context of finding routes, cities are represented as vertices and flights as edges.
