|Abstract: ||The travelling salesman problem is considered to be a classic example of what is known as a tour problem. Essentially, any type of tour problem involves making a series of stops along a designated route and making a return journey without ever making a second visit to any previous stop. Generally, a tour problem is present when there is concern on making the most of available resources such as time and mode of travel to accomplish the most in results. Finding a solution to a tour problem is sometimes referred to as discovering the least-cost path, implying that the strategic planning of the route will ensure maximum benefit with minimum expenditure incurred.
The concept of the travelling salesman problem can be translated into a number of different disciplines. As a form of optimization that is useful in both mathematical and computer science disciplines, combinatorial optimization seeks to team relevant factors and apply them in a manner that will yield the best results with repeated usage.
This study formulated a real-life problem of WAEC as a TSP, modelled as network problem and applies dynamic programming approach in solving the problem. It was observed that the route that gave minimum achievable inspection plan was 1 – 3 – 6 –9 – 10 at the minimum distance of 183 km, by visiting as many as five centres on the route.|
