Diversifying Estimation Errors: An Efficient Averaging Rule for Portfolio Optimization

Portfolio Optimization Based on Robust Estimation Procedures

An Optimization Method for Proportionally Diversifying Search Results

The problem of diversifying search results has attracted much attention, since diverse results can provide non-redundant information and cover multiple query-related topics. However, existing approaches typically assign equal importance to each topic. In this paper, we propose a novel method for diversification: proportionally diversifying search results. Specifically, we study the problem of r...

Lexicographic goal programming approach for portfolio optimization

This paper will investigate the optimum portfolio for an investor, taking into account 5 criteria. The mean variance model of portfolio optimization that was introduced by Markowitz includes two objective functions; these two criteria, risk and return do not encompass all of the information about investment; information like annual dividends, S&P star ranking and return in later years which is ...

AN EFFICIENT METAHEURISTIC ALGORITHM FOR ENGINEERING OPTIMIZATION: SOPT

Metaheuristic algorithms are well-known optimization tools which have been employed for solving a wide range of optimization problems so far. In the present study, a simple optimization (SOPT) algorithm with two main steps namely exploration and exploitation, is provided for practical applications. Aside from a reasonable rate of convergence attained, the ease in its implementation and dependen...

The argument for diversifying the NIH grant portfolio

The United States has been a leader in biomedical science for decades, in large part because of the strategy used by the National Institutes of Health (NIH) to invest its budgetary portfolio. They identified talented young scientists from each generation and gave them the resources they needed to initiate and maintain strong research programs. However, recently this investment has become less d...
