Abstract. This paper presents the cooperation between two searchers at the origin to seek for a random walk moving target on the line. Any information of the target position is not available to the searchers all the time. Rather than finding the conditions that make the expected value of the first meeting time between one of the searchers and the target is finite, we show the existence of the optimal search strategy which minimizes this first meeting time. The effectiveness of this model is illustrated

"A Survey on Human Mobility Modeling" The speaker of this presentation is Hugo Serrano Barbosa Filho from Florida Tech. The topic of this presentation is the importance of human mobility modeling and several human mobility modeling methods Human mobility model represents the movement of human and how they change their positions over time[1]. At the beginning of presentation Mr. Filho answered two questions. First, human mobility research is about analyze and predict human daily activities and

Statistical Methods & Capital Markets Testing Random Walk Hypothesis Nicolas Mancini * Table of Content Abstract Theoretical background Methodology Data & Results Comparison Conclusion References ------------------------------------------------- I. Abstract The aim of this paper is to test the random walk hypothesis by applying the runs test on time series of several selected stocks. The random walk theory is the theory that stock prices changes have the same

Markov Chains Game Introduction Probabilistic reasoning goes a long way in many popular board games. Abbott and Richey [1] and Ash and Bishop [2] identify the most portable properties in Monopoly and Tan [3] derives battle strategies for RISK. In RISK, the stochastic progress of a battle between two players over any of the 42 countries can be described using a Markov Chain. Theory for Markov Chains can be applied to address questions about the probabilities of victory and expected losses in battle

COMPETITIVE ADVANTAGES AND DISADVANTAGES As members of Chester F73524, we see ourselves as the biggest player in the low-tech industry. This is a direct result of the competitive advantage that we possess. By making heavy investments in fixed assets early in the simulation, we have been able to create a low tech product to be reckoned with; one that is characterized by sizeable contribution margins, high accessibility and awareness, and a premium price. As a result, we have achieved an industry-high

"A Random Walk Down Wall Street" There is a sense of complexity today that has led many to believe the individual investor has little chance of competing with professional brokers and investment firms. However, Malkiel states this is a major misconception as he explains in his book "A Random Walk Down Wall Street". What does a random walk mean? The random walk means in terms of the stock market that, "short term changes in stock prices cannot be predicted". So how does a rational investor determine

In some journal an interesting example related to the idea of random walk is that random walk is like a blindfolded chimpanzee throwing darts at Wall Street and selects any portfolio which yields equal to the portfolio selected by any expert. The idea of random walk is just like throwing a towel on the stock of different category to formulate an appropriate portfolio at lower cost. Most of the investors try to

managers working for mutual funds, pensions and other types of institutional accounts, have been found to have typically access to private information to achieve abnormal gains but may not perform above the overall market on a regular basis. The Random Walk Model is a different paradigm of the Hypothesis of Efficient Markets. This model was initially examined by Kendall (1953). The model states that the price fluctuations of stocks do not depend on each other and have the same probability distribution

also concluded that " The calculated anticipation of the investor is of no value" . Holbrook (1934), has found that the subsequent changes in stock prices are not dependent on each other and are also uncorrelated and he concluded that they are random. Later, many of the researchers [Kendall (1953), Osborne (1959), Fama (1965)]have supported the findings of Holbrook. These studies used the statistical techniques to test the independence of stock price. The Efficient Market Hypothesis was established
