Study The Effects Of Multilevel Selection In Multi-Population Cultural Algorithm, Dilpreet Singh
Study The Effects Of Multilevel Selection In Multi-Population Cultural Algorithm, Dilpreet Singh
Electronic Theses and Dissertations
This is a study on the effects of multilevel selection (MLS) theory in optimizing numerical functions. Based on this theory, a new architecture for Multi-Population Cultural Algorithm is proposed which incorporates a new multilevel selection framework (ML-MPCA). The approach used in this paper is based on biological group selection theory that states natural selection acts collectively on all the members of a given group. The effects of cooperation are studied using n-player prisoner’s dilemma. In this game, N individuals are randomly divided into m groups and individuals independently choose to be either cooperator or defector. A two-level selection process is …

Performance Evaluation Of Competing Data Structures, Mohsen Tavakoli
Electronic Theses and Dissertations
Pathfinding is an essential part of many applications, including video games and robot navigation. A pathfinding algorithm usually finds a path from the given starting point to the endpoint. Many different implementations of pathfinding solutions exist in the industry. One of the most known and used of these algorithms is A*. A* will find the shortest path from the starting point to the endpoint. Classic A* algorithm can guarantee the shortest path to the desired destination which was introduced in 1968 by Hart, Nilsson, and Raphael. A* is widely used in the game industry to solve the shortest path problem. …
Development Of Optimal Material Extrusion Additive Manufacturing Tool Path Parameters For Minimizing Void Regions Using Contemporary Tool Path Solutions, Hasti Eiliat
Electronic Theses and Dissertations
A problem with the planning solutions for the additive manufacturing material extrusion process is a lack of optimization strategies to improve upon the standard raster and contour toolpaths. After experimental testing, it was recognized that a component’s strength relationship with respect to the volume of material usage is inconsistent and that failures occurred in regions of voids. From previous studies, it was found that a build orientation in the material extrusion process influences the support material requirements, processing time, surface finish, voids volume, etc. This dissertation aims to identify, minimize, and manage void regions during the toolpath generation, and studies …
A New Measure For Optimization Of Field Sensor Network With Application To Lidar, Farsam Farzadpour
A New Measure For Optimization Of Field Sensor Network With Application To Lidar, Farsam Farzadpour
Electronic Theses and Dissertations
This thesis proposes a solution to the problem of modeling and optimizing the field sensor network in terms of the coverage performance. The term field sensor is referred to a class of sensors which can detect the regions in 2D/3D spaces through non-contact measurements. The most widely used field sensors include cameras, LiDAR, ultrasonic sensor, and RADAR, etc. The key challenge in the applications of field sensor networks, such as area coverage, is to develop an effective performance measure, which has to involve both sensor and environment parameters. The nature of space distribution in the case of the field sensor …
