Approaches for solving some scheduling and routing problems
No full textWe study approaches for finding good solutions, and lower bounds, for three difficult combinatorial optimisation problems.The supply ship travelling salesman problem is a simplification of a situation faced by a naval logistics coordinator who must direct a support vessel tasked with resupplying ships in a fleet. It is a generalisation of the travelling salesman problem in which the nodes are in motion, each following some predetermined route. We apply dynamic programming state-space relaxation
techniques, producing lower bounds for the problem that are 73% to 84% of the best solution, on average. We also apply heuristics to find good solutions to this NP-hard problem, showing that restricted dynamic programming approaches outperform simple 2-opt and 3-opt local search procedures
for instances with 20 nodes.We introduce the supply ship scheduling problem, another roblem inspired by a support vessel environment. We wish to minimise the number of mobile machines required to process a set of jobs; each job is in a different stationary location and features a fixed start time. Jobs may be simultaneously processed by multiple machines, obtaining a speed-up in processing time. We represent the problem as a directed graph and use the minimum flow in a transformed network to determine the minimum number of machines. We present a neighbourhood structure based on the maximum cut, applying it
within descent and tabu search procedures. We construct a restricted dynamic programming based approach, but this is outperformed by the tabu search algorithm.The task allocation problem, arising in distributed computing, is to assign a set of tasks to a set of processors so that the overall cost is minimised. Costs are incurred from processor usage, interprocessor communication and task execution. We construct, and try to improve, semidefinite programming relaxations to find lower bounds for variants of this NP-hard problem. We develop a branch-and-bound approach to find optimal solutions, but this is only effective for small instances
The Origins and Development of the Indian Removal Policy
No full text158 leaves.The problem. The purpose of this work is to present a descriptive narrative of the men, problems and events which made up American Indian policy from 1800 to 1840. A primary objective is to trace the origins and mark the major developments of the Federal Government's policy of removing Indian tribes to the western side of the Mississippi River. Andrew Jackson's role in these developments will be stressed.
Procedure. After a brief review of pre-Jeffersonian Indian policy, the thesis traces the events which led from the formulation of the removal concept at the beginning of
the 19th century to its final culmination in the late 1830's. By combining primary sources such as government documents and
collected correspondence with recent secondary books and articles, the thesis focuses on the formulation of removal and not the actual removal operations.
Findings. The study finds that while removal was considered prior to the War of 1812, it was not until Indian military power east of the Mississippi was broken in that conflict, that removal came to be seen as the final
solution to the Indian "problem" in the 1820's. James Monroe, John C. Calhoun and other federal leaders actually defined the policy which Andrew Jackson implemented. Jackson used
this foundation, supported states' rights and allowed Congress to provide the necessary legislation for removal

Father Andrew Mullen 1790-1818: a study in early nineteenth century spirituality
No full textThis thesis is laid out in three parts: Part I. The life and death of Andrew Mullen. The life is based, to a large extent, on a long letter to his mother, Catherine Mullen, dated 7 January 1810. The letter gives a definite insight into his spirituality based on his membership of the Archconfraternity of the Blessed Sacrament. There is a hint that he had a premonition of an early death. Part II. The burial of Andrew Mullen and the immediate cult to him This is based on documentary evidence. Part III. Most of this part is a catalogue of testimonies taken from 1993 onwards. Then there is the conclusion on the popular devotion to Andrew Mullen stressing the theological aspect of the subject. In the course of writing the thesis it was decided to separate the documentary evidence from the oral tradition. This was advantageous in developing the thesis, and the documents provided a secure basis for the oral tradition. Two pieces of information were found in March 1997. They are death notices: 2 January 1819, The Leinster Journal and 7 January 1819, The Car low Morning Post. There is a slight discrepancy between the two on the date of his death. Also this discrepancy shows a slight difference from the date of the tombstone
