Predoctrinal deliberations about the employment of US armed forces, captured in Joint Doctrine Notes, remain critically understudied. Using comparative text analysis, this article identifies changes recent Note depictions military strategy. These risk distorting logic strategy, sacrificing means-ends integration to organizational impulse, and raising prospect future shortfalls strategic effecti...

Using a Genetic Algorithm (GA), an artificial intelligence technique, this study proposes an user-interactive dynamic portfolio selection strategy using a decision support system that will generate an optimal investment mix of assets based on user selection by maximizing the return of the Sharpe Ratio, a measure of the excess return received on a portfolio for the increase of volatility by acqu...

The “Agriculture, Countryside and Farmer” issues are an important content related to the country’s overall strategy, and to develop characteristic agriculture is the fundamental way to solve the “Agriculture, Countryside and Farmer” issues. The Hongyang kiwifruit industry in Cangxi County of Sichuan Province has played an important role in increasing farmers’ income, optimizing the agricultural...

This paper describes NTCIR-5 experiments of the CLIR-J-J task, i.e. Japanese monolingual retrieval subtask, at the Yahoo group, focusing on comparative studies of the feedback effectiveness with two retrieval methods, namely BM25TF*IDF and a KL-divergence language modeling approaches. An “automatic feedback from top k documents” strategy was surprisingly successful in this test collection. We c...

We have recorded the behaviour of several users solving the same task with an interactive database program. Since the number of users exceeds that of strategies, multiple users will have a strategy in common. Our aim is to find groups of users sharing the same strategy. Following each of three methods (correlation, intersection and exclusion) we define a comparative metric among task solving be...

Supermodular games are an interesting class of games that exhibits strategic complementarity. There are several compelling reasons like existence of pure strategy nash equilibrium, dominance solvability, identical bounds on joint strategy space etc. that make them a strong candidate for game theoretic modeling of economics. Supermodular games give a sound framework for analysis as it is based o...

This report documents the development of an autonomous stock trading agent within the framework of the Penn-Lehman Automated Trading (PLAT) simulator. The three approaches presented take inspiration from reinforcement learning, myopic trading using regression-based price prediction, and market making. The performance of these approaches is assessed separately using a fixed opponent strategy, SO...

Data summarization is very important for many data analysis tasks. In this paper we propose a simple but efficient data summarization algorithm, which outputs a histogram for multidimensional data, and make a comparative study of its usage with different distributions and with existing algorithms. The idea is to iteratively grow and modify regions of homogeneous data. This is a different strate...

This paper investigates a number of alternatives to the standard genetic programming operators, along with an alternative to the standard evolutionary search strategy, and compares and analyses their performance. Four test problems with differing properties are used to assess which operators perform best for which strategy, the comparative performance of alternative search strategies, and the e...

Detection of task-solving strategies is one way to reconstruct cognitive structures. When the number of users exceeds the number of possible strategies, many users will have a strategy in common. Based on these common features, the aim of this paper is to find automatic methods which group users sharing the same strategy. Following two different methods, intersection and exclusion, we define a ...
