Yes,there is an obvious algorithm to test each possible trip and find the best one. The trouble is the exponential run-time.

An algorithm.
If you cannot find any iterative algorithm for the problem, you have to settle for a recursive one.
By preparing test cases we can test an algorithm. The algorithm is tested with each test case.
An algorithm is just a description of a series of steps used to solve a specific problem.
An intractable problem is one for which there is an algorithm that produces a solution - but the algorithm does not produce results in a reasonable amount of time. Intractable problems have a large time complexity. The Travelling Salesman Problem is an example of an intractable problem.
Some effective heuristics for solving the traveling salesman problem efficiently include the nearest neighbor algorithm, the genetic algorithm, and the simulated annealing algorithm. These methods help to find approximate solutions by making educated guesses and refining them iteratively.
Imagine an island with a road network joining several towns. You want to visit each town before returning to your start point. Finding the best solution to this is the travelling salesman problem. now imagine you want to resurface every road on the network. To do this in the shortest distance is the Chinese postman problem. Essentially for the travelling salesman problem you have to visit every vertex. For the Chinese postman problem every edge must be visited.
The 2-approximation algorithm for the Traveling Salesman Problem is a method that provides a solution that is at most twice the optimal solution. This algorithm works by finding a minimum spanning tree of the given graph and then traversing the tree to form a tour that visits each vertex exactly once.

A packman is a person who travels with a pack, especially a travelling salesman.
Harry A. Thompson has written: 'The travelling salesman'
A problem is a situation that needs to be solved, while an algorithm is a step-by-step procedure for solving a problem. In problem-solving, the problem is the challenge to be addressed, while the algorithm is the specific method used to find a solution to the problem.

Yes, the traveling salesman problem is an example of a co-NP-complete problem.
An algorithm is the process by which you solve a problem
This is the definition of an algorithm - a list of orders of how to solve a given programming problem.
