Seeker optimization algorithm (SOA) is a novel search algorithm based on simulating the act of human searching, which has been shown to be a promising candidate among search algorithms for unconstrained function optimization. In this article we propose a modified seeker optimization algorithm. In order to enhance the performance of SOA, our proposed approach uses two search equations for produc...

x0. Introduction. Consider a game played by 2 players, whom we call the hider and the seeker. Let S be a simplex of dimension n, with vertices x 0 , x 1 ; : : :; x n , and M a subcomplex of S, known to both the hider and the seeker. Let be a simplex of S, known only to the hider. The seeker is permitted to ask questions of the sort \Is vertex x i in ?" The seeker's goal is to determine whether ...

We study a multi-step hider-seeker game where the hider is moving on a graph and, in each step, the seeker is able to search c subsets of the graph nodes. We model this game as a zero-sum Bayesian game, which can be solved in weakly polynomial time in the players’ action spaces. The seeker’s action space is exponential in c, and both players’ action spaces are exponential in the game horizon. T...

In an innovation contest, a rm (the seeker) facing an innovation related problem (e.g. a technical R&D problem) posts this problem to a population of independent agents (the solvers) and then provides an award to the agent that generated the best solution. In this paper, we analyze the interaction between a seeker and a set of solvers. Prior research in Economics suggests that having many solv...

In this paper, we propose an adaptive and opportunistic forwarding mechanism that is able to match mobility characteristics in Delay Tolerant Networks (DTNs). Our protocol, Seeker, empowers nodes with the ability to estimate future contact opportunities based on a history of pair-wise contacts. Furthermore, Seeker is able to adjust and rewind forwarding and buffering decisions on the fly. This ...

retrieval? It is legitimate for the reader to ask why a distinction is made by this book between the terms ‘interactive information retrieval’ and ‘information retrieval’. Surely, in the current context of information seeking through web search engines, it is clear that information retrieval necessarily involves some form of interaction between searcher and system. An answer to this question li...

The accuracy of target position detection in IR seeker depends on the accuracy of tracking error signal (TES) extraction from seeker Field of View (FOV). The type of reticle inside the seeker determines the output modulation signal that carries the TES. In this paper, the stationary wagon wheel reticle is used, which makes the type of the output signal as FM modulation in the linear region of F...

Ross-Hime Designs, Inc. presents the results of its research and development of “Low Cost Light-Weight Seeker Gimbals.” The Super Seeker, a patent-pending gimbal design, offers a swiveling yoke design lower in cost than current gimbal designs and weighing significantly less than traditional gimbal systems while enabling a doubling of the sensor’s surface area. The swiveling yoke design has buil...

This article is the fifth in a series of articles from our study examining information-seeking behavior in relation to information-retrieval (IR) interaction. This article focuses on the examination of the interaction variables within Saracevic’s (1989) triadic IR model. The analysis involved an examination of the information-searching behavior of academic researchers during a mediated interact...
