However, it is the purpose of this paper to show that the computational complexity drastically improves if the jobs are divided into a small number of groups where each group consists of \\similar" jobs. Such situations can be found in applications where the jobs in a group are identical or the jobs in a group require a similar ... Fetch Doc

Lecture 5: Introduction To Approximation Algorithms
Lecture 5: Introduction to Approximation Algorithms Many important computational problems are difficult to solve optimally. In fact, many of those problems are NP-hard1, which means that no polynomial-time algorithm exists that solves the problem optimally unless P=NP. A well-known example is the Euclidean traveling ...

Traveling Salesman Problem with time windows (TW-TSP). We consider two versions of TW-TSP. In the rst version, jobs are lo-cated on a line, have release times and deadlines but no processing times. A geometric interpretation of the problem is used that generalizes the Erd}os-Szekeres Theorem. We present an O(logn) approximation algo- ... Fetch Here

Traveling salesman problem. Sometimes, the number of ‘interesting’ subsets is fairly small, and then an even better time complexity might be possible. This will be illustrated by discussing the graph 3-colorability problem. The traveling salesman problem (TSP). A traveling salesman has to visit the cities 1 to n. ... Retrieve Document
