摘要: The Traveling Salesman Problem or TSP is a fundamental and well-known problem in combinatorial optimization. At present, the most successful algorithms for solving large-scale instances of to proven (near-)optimality are based on integer programming. This entry introduces main theoretical algorithmic tools involved. Topics covered include: formulations TSP, polyhedral theory, separation routines, exact algorithms. Keywords: traveling salesman problem; integer programming; polyhedral combinatorics
