Handling Large-Scale Traveling Salesperson Problems

We’ve figured out that solving TSP is computationally challenging due to its inherent combinatorial nature. With every store we add for the salesperson to find the overall shortest route, the potential solutions grow exponentially.

Efficient algorithms

Scalability in the context of TSP refers to the ability of algorithms to handle increasingly large amounts of locations efficiently. It’s a critical consideration in addressing the practical applicability of TSP algorithms, especially as the problem size grows in terms of the number of stores (nodes) to visit.

The primary challenge in scalability arises due to the exponential increase in computational resources required to solve the TSP for more locations. Computational time and memory requirements can grow rapidly, making it infeasible to use exact algorithmsExact algorithms provide the optimal solution, computing the absolute shortest route without approximation., especially as the problem size surpasses a certain threshold.

• Brute force: The brute force approach to solving TSP involves exhaustively generating and evaluating all possible routes to determine the shortest one. Each permutation of the stores represents a potential route, and the algorithm computes the total distance for each permutation. While this method guarantees finding the optimal solution by evaluating all possibilities, its computational complexity grows factorially with the increasing number of stores. This means that for each additional store, the number of permutations to evaluate increases, making the ...
