Show moreUncertainty and noise are frequently-encountered obstacles in real-world applications of numerical optimization. The practice of optimization that deals with uncertainties and noise is commonly referred to as robust optimization. This thesis concentrates on robust optimization w.r.t the parametric uncertaintiesin the search variables. These parametric uncertainties are assumed to be structurally symmetric, additive in nature, and can be modeled in a deterministic or aprobabilistic fashion. This dissertation empirically studies the models, algorithms, and techniques utilized for surrogate-assisted robust optimization in this context. Based on the studies performed in the dissertation, we conclude that Kriging, SVM, and Polynomial Regression are useful modeling techniques to solve robust optimization problems. We also validate the applicability of Autoencoders and PCA for addressing high-dimensional problems. Lastly, we find that mini-max robustness is the most efficient robustness formulation technique in practical scenarios. Show less

Show moreThe relationship between the VOC (Dutch East India Company) and its servants fundamentally changed with its decline (1740-1796). The changing circumstances of the eighteenth century demanded too much of the VOC. The solution to these new demands was not sought in new capitalization from Europe, but in a combination of cutbacks on activities in Asia and augmented usage of servants’ fortunes. The domains the VOC retreated from were filled by privileges to the servants. As the VOC depended more on its servants during its decline, the balance of power between them shifted in favour of the servants. This change in balance demanded more of the servants, forcing them to organize themselves differently to meet the new challenges. In the end, this change of perspective makes the development much more comparable to the changes the English East India Company went through, and provides a new perspective on changes in the position of the EIC-servants in the period around Plassey (1757).

Show moreFocussing on individuals and institutions, the economic and social condition of the people of Fort Cochin between 1781 and 1830 has been studied. This study of the Dutch East India Company's (VOC) establishment on the south west coast of India provides a detailed research into the functioning of the company and its personnel there. To begin the company's presence on the coast around the year 1750, after it had been defeated by the raja of Travancore, on whom it was dependant for purchasing pepper, is summarized. It places the VOC's Malabar Command on the larger web of the VOC network in Asia. The VOC strove hard to maintain its pepper monopoly on the coast, but non-VOC trade in pepper contined. Three consecutive commanders between 1751 and 1764 constantly strove to expand the company's territorial possesions on the coast resulting in a metamorphosis in the command's functioning. The components of the Fort Cochinsociety and the relations among the different communities that made up the social world of Fort Cochin receive attention in the book. Starting with the company men and analysing the recruitment pattern of the VOC in Malabar Command, one is faced with rather startling facts. The majority of the VOC personnel in the mercantile sections were locally recruited. European women were a rare sight in Fort Cochin. The European company men married mestizo women and through them became rooted in Cochin. Their sons joined the Dutch company thereby forming 'VOC-family'. While Dutch men were securing their future on the Malabar Coast, the EIC was expanding in India. During the 1780-1784 Anglo-Dutch war, many Dutch settlements were lost to the British. Fort Cochin evaded the fate as the EIC was yet to conquer Mysore, a formidable power in the south. When in 1795, the British forces conquered Fort Cochin, the servants of the Dutch company were forced to decide their future course of action. The social and economic condition of the people of Fort Cochin under the British administration has been analysed and lives of former VOC servants and their families after the transition has been portrayed Show less
