Hoogeveen Centre for Mathematics and Computer Science, P.O. Box 4079, 1009 AB Amsterdam, Netherlands Received March 1990 Revised September 1990 For the traveling salesman problem in which the distances satisfy the triangle inequality. One of the most famous approaches to the TSP, and possibly one of the most renowned algorithms in all of theoretical Computer Science, is Christofides' Algorithm. Created by Nicos Christofides in the late 1970s, it is a multistep algorithm that guarantees its solution to the TSP will be within 3/2 of the optimal solution The Omega Ratio is a recent performance measure. It captures both, the downside and upside potential of the constructed portfolio, while remaining consistent with utility maximization

- Due to its speed and 3/2 approximation guarantee, Christofides algorithm is often used to construct an upper bound, as an initial tour which will be further optimized using tour improvement heuristics, or as an upper bound to help limit the search space for branch and cut techniques used in search of the optimal route

In the long run, it's really better to understand the graph theory terminology, but for now, here is an explanation of Christofides's algorithm. I'm not an expert in this area so I can't offer much by way of intuition. Also, I should note that by now, better algorithms are known for some variants, see for example the recent survey by Vygen Given a symmetric metric cost on n vertices including two prespecified endpoints, the problem is to find a shortest Hamiltonian path between the two endpoints; Hoogeveen showed that the natural variant of Christofides' algorithm is a 5/3-approximation algorithm for this problem, and this asymptotically tight bound in fact has been the best approximation ratio known until now. We modify this algorithm so that it chooses the initial spanning tree based on an optimal solution to the Held-Karp. Subscribe to this blog.

Note that when =0, then we get 1.5 c(OPT). Let c(x,y) be cheapest traversal to go from x to y, such that we start at g(x) and end at g(y). Main problem Lack of triangle inequality Use Christofides method. Combine with previous approach to get a feasible solution. Single Gas Station Problem Suppose the salesman lives near a gas station Christofides is one of the better lecturers in the department IMO. He's really adamant about getting his very structured thoughts out on the board before anyone asks anything (Please wait a minute!) which I sort of appreciate. The tests don't demand a lot of your theoretical knowledge of how each method works--just crunch the numbers.

Heuristic methods can be integrated into standard optimization procedures in three ways, broken out by the stage in which they're employed: pre-optimization, post-optimization, and during. The practice of communicating research findings to participants has been identified as important in the research ethics literature, but little research has examined empirically how this occurs and. To include edge 0-1, we add the edge cost of 0-1, and subtract an edge weight such that the lower bound remains as tight as possible which would be the sum of the minimum edges of 0 and 1 divided by 2. Clearly, the edge subtracted can't be smaller than this This is an implementation of the Christofides algorithm. The algorithms is a $3/2$-approximation assuming that the input graph satisfies triangle inequality and all edge weights are nonnegative. The implementation requires the input graph to be undirected and complete. The worst case running time complexity is $\mathcal{O}(V^3E)$
