Описание книги

A thorough look at how societies can use cultural algorithms to understand human social evolution For those working in computational intelligence, developing an understanding of how cultural algorithms and social intelligence form the essential framework for the evolution of human social interaction is essential. This book, Cultural Algorithms: Tools to Model Complex Dynamic Social Systems , is the foundation of that study. It showcases how we can use cultural algorithms to organize social structures and develop socio-political systems that work. For such a vast topic, the text covers everything from the history of the development of cultural algorithms and the basic framework with which it was organized. Readers will also learn how other nature-inspired algorithms can be expressed and how to use social metrics to assess the performance of various algorithms.  In addition to these topics, the book covers topics including: ● The CAT system including the Repast Simphony System and CAT Sample Runs ● How to problem solve using social networks in cultural algorithms with auctions ● Understanding Common Value Action to enhance Social Knowledge Distribution Systems ● Case studies on team formations ● An exploration of virtual worlds using cultural algorithms For industry professionals or new students, Cultural Algorithms provides an impactful and thorough look at both social intelligence and how human social evolution translates into the modern world.

In addition to the constraints and basic domain knowledge of the ConesWorld problem, there is also a series of flags for each cone. These flags indicate the directional change a cone may take during an update. There are strict maximum and minimum values that the dimension variables of a cone may change between. The movement between these extremes is cyclical in nature, moving the cone first toward one extreme and then back toward another, similar to how the pistons in an engine can move up and down. Should a cone undergoing an update exceed its dimensional limits, its flag is switched to denote its new increasing or decreasing status, and the amount by which it exceeding its limit then becomes additional change in its new dimension.

For an example of this, assume the cone height limits are set between 1 and 3, and the rate of change is restricted to 0.25 at the most for any single update. If a cone's height is already at 2.80 with its directional flag indicating that it should increase, it will have 0.25 added to it, and it will exceed the height limit of 3 by 0.05. In this case, its flag will be triggered to indicate that it is now decreasing, and the overflow of 0.05 will be taken away from the height of the cone, resulting in a cone of 2.95 height. The next update to the cone, for example 0.20, will result in the cone's height being updated to 2.75, as its directional flag is still indicating that it is decreasing. This decrease will continue until the cone hits the lower limit, at which point the flag will be toggled, the overflow will be added back in, and the cycle will continue again.
