Abstract: We give a fully polynomial time approximation scheme (FPTAS) for the optimum fractional solution to the Steiner forest problem. This can easily be generalized to obtain an FPTAS for a ...

Abstract: The present work studies a maximum multicommodity flow problem with local constrains, which not only enrich the content of the multicommodity flow problem, but also can be used to operate ...

Start working toward program admission and requirements right away. Work you complete in the non-credit experience will transfer to the for-credit experience when you ...

A python file containing an implemented approximation algorithm A python file containing an implemented simulated annealing implementation A python file used to compare the findings of the two ...

Management Science, Vol. 34, No. 3, Focussed Issue on Heuristics (Mar., 1988), pp. 402-410 (9 pages) A new approximate algorithm for multidimensional zero-one knapsack problems with all positive ...

We develop new algorithmic approaches to compute provably near-optimal policies for multiperiod stochastic lot-sizing inventory models with positive lead times, general demand distributions, and ...

This course studies approximation algorithms – algorithms that are used for solving hard optimization problems. Such algorithms find approximate (slightly suboptimal) solutions to optimization ...

The traveling salesman problem is one of the basic problems that many theoretical computer scientists have been working on. Many scientists think that there is no algorithm for the traveling salesman ...
