The traveling salesman problem involves efficient resource usage and minimizing energy expenditure. It is a classic example of the tour problem, where stops along a route are made without revisiting previous ones. Combinatorial and discrete optimization are related to this problem and useful in mathematics and computer science. The goal is to achieve maximum benefit with minimum resource investment.
The traveling salesman problem is a traditional problem that has to do with using resources most efficiently while also expending the least amount of energy in that usage. The designation of this type of problem dates back to the days of the traveling salesman, who often wanted to arrange his travel so that he could visit most cities without having to go back and pass through a particular city more than once.
In a broader sense, the traveling salesman problem is considered a classic example of what is known as the tour problem. In essence, any type of tour problem involves a series of stops along a designated route and a return trip without ever making a second visit to a previous stop. Generally, a touring problem is present when there is concern about making the best use of available resources such as time and travel arrangements to get the most out of results. Finding a solution to a touring problem is sometimes referred to as discovering the least expensive route, implying that strategic route planning will ensure maximum benefit for minimum expense incurred.
The concept of the traveling salesman problem can be translated into several disciplines. For example, the idea of combinatorial optimization has a direct relationship to the traveling salesman model. As a form of optimization useful in both mathematics and computer science disciplines, combinatorial optimization seeks to group relevant factors together and apply them in a way that produces the best results with repeated use.
Similarly, discrete optimization attempts to achieve the same goal, although the term is sometimes employed to refer to tasks or operations that occur once rather than recurringly. Discrete optimization is also useful in computer science and mathematical disciplines. Furthermore, discrete optimization has a direct relationship to computational complexity theory and is considered useful in the development of artificial intelligence.
While the images associated with a traveling salesman problem may seem like an oversimplification of these types of detailed options for optimization, the idea behind the images helps explain a fundamental basis for any type of optimization that aims for efficiency. The solved traveling salesman problem will bring enormous benefits in terms of maximum return for minimum investment of resources.
