It has been successfully applied to a large number of numerical optimization problems including telecommunications problems [31].
The telecommunications problems occurred because part of the local conventional 'fixed-line' network (including connections to TCH) was directly damaged in the blast, and because all mobile phone networks quickly became overloaded due to heavy use by the public and arriving media personnel.
But because price wars have contributed to the telecommunications industry's problems, further pressure on that front would add to the challenges facing other carriers, particularly the big long-distance companies AT&T and Sprint.
Wall Street lost confidence three years ago in Motorola and Galvin's ability to solve the telecommunications giant's problems, issues Galvin has been either incapable or unwilling to tackle.
The resulting control law is applied to a telecommunications network traffic control problem as an example.
The 3G universal mobile telecommunications system (UMTS) planning problem is combinatorially explosive and difficult to solve optimally, though solution methods exist for its three main subproblems (cell, access network, and core network planning).
This not only solved an important problem in telecommunications and computer science, it opened up a whole new field of study.
Due to its proximity to the blast and the telecommunications difficulties, the biggest problem at TCH was the lack of medical and nursing staff.
They are among the most effective solution strategies for solving optimization problems in practice and have been applied to a very large variety of problems in telecommunications, computer communications, and network design and routing.
Mr. Kimmelman said that while Mr. McCain often identified industry problems in telecommunications and other areas, he had little faith in regulators to solve them.
