Certainly. I'll explain TSP in further detail:

The **Traveling Salesman Problem (TSP)** asks the following question: "Given a list of cities and the distances between each pair of cities, what is the shortest possible route that visits each city exactly once and returns to the origin city?" The problem was inspired by traveling salesmen (hence the name) who often had to make journeys like this in their line of work. However, the problem has since been recognized in mathematics and is one of the most studied problems in optimization, as representative of a much wider class of real-world and theoretical logistical path-finding problems that can be reduced to it.  

More formally, TSP is a *minimization problem* of finding the *shortest cyclical path* that visits *every vertex* of an *undirected*, *weighted* *graph*. The **graph** is merely the formal mathematical way to refer to the map of cities the salesmen desires to visit.  Each city is a **vertex** on the graph, and the vertices are connected by **edges** (these represent the roads between cities the salesman can use to travel between them).  Each edge has a **weight**, which is a number representing the distance between the two cities connected by that edge.  The weights are used to calculate the *total distance of a path* (by adding up all the edge weights on a path). TSP is a **minimization problem**, because TSP seeks the *shortest path* that *satisfies the constraints*.  And the path should be **cyclical** because the typical salesman wishes to return home after their journey (end on the vertex he started on). In fact, TSP is a *specific case* of the *more general* **Hamiltonian Path problem**, which does not require the start and end to be the same, but still requires every vertex be visited.  

Any problem that can be *reduced to* or *found equivalent to* the above definition of the TSP is often also called a **Traveling Salesman Problem**, even if it does not involve salesmen.  The TSP has several such applications, even in its purest formulation.  For example, planning, logistics, and even the manufacture of microchips. Slightly modified, it appears as a sub-problem in many areas, such as DNA sequencing. In these applications, the concept of a city (or vertex) represents, for instance, customers, soldering points, or DNA fragments. Likewise, the concept distance (weights) represents traveling times or cost, or a similarity measure between DNA fragments. The TSP also appears in astronomy, as astronomers observing many sources will want to minimize the time spent moving the telescope between the sources; in such problems, the TSP can be embedded inside an **optimal control problem**. In many applications, additional constraints such as limited resources or time windows may be imposed.

Furthermore, TSP also refers to a *class of similar problems* that are **variants**, and some that are **generalizations**, of the above definition of TSP.  For instance, the **Asymmetric Traveling Salesman Problem** is a variant where the graph is **directed** (some or all edges/roads can be one-way) instead of *undirected* (all two-way, or *symmetric* instead of *asymmetric*).  Traffic collisions, one-way streets, and airfares for cities with different departure and arrival fees are examples of how this asymmetry can occur in real problems.  A few examples of the many other ***TSP variants and generalizations*** include: **Bottleneck TSP**, the **Traveling Politician Problem**, and the **Traveling Purchaser Problem**.

I hope this helps you better understand the Traveling Salesman Problem in detail.  Do you have any questions, or something else I can assist you with?
