No Sex or Age Difference in Dead-Reckoning Ability among Tsimane Forager-Horticulturalists

Benjamin C. Trumble, Steven J. C. Gaulin, Matt D. Dunbar, Hillard Kaplan, Michael Gurven
2015 Human Nature  
Here we examine sex-and age-based variation in one kind of spatial ability related to navigation, dead-reckoning, among Tsimane forager horticulturalists living in lowland Bolivia.  ...  Seventy-three participants (38 male) aged 6-82 years pointed a handheld global positioning system (GPS) unit toward the two nearest communities and the more distant market town.  ...  There are a number of hypotheses regarding the evolutionary bases of male-biased spatial ability.  ...

Evolving Indoor Navigational Strategies Using Gated Recurrent Units In NEAT [article]

James Butterworth, Rahul Savani, Karl Tuyls
2019 arXiv   pre-print
We extend NEAT to include Gated Recurrent Units (GRUs) to help deal with long term dependencies.  ...  Bug algorithms are an alternative that use relatively little processing power, and avoid high memory consumption by not building an explicit map of the environment.  ...  Extending HyperNEAT to include connections that are modified online [34, 35] generates networks that can solve the continuous T-maze domain by instilling them with memory.  ...

RETRACTED: A Rule Based Evolutionary Algorithm for Intelligent Decision Support

Wissam M. Alobaidi, David J. Webb, Eric Sandgren
2017 Open Journal of Optimization  
Genetic or evolutionary search algorithms seek and exploit the structure of a problem by operating on an encoding which represents the problem variables.  ...  In order to speed up the solution process as well as produce a more refined solution, a rule based encoding is proposed.  ...  If the current strategy was viewed as the chromosome of a genetic algorithm, this approach could be considered a rule based evolutionary approach.  ...

Beyond black-box optimization: a review of selective pressures for evolutionary robotics

Stephane Doncieux, Jean-Baptiste Mouret
2014 Evolutionary Intelligence  
Evolutionary robotics is often viewed as the application of a family of black-box optimization algorithms -evolutionary algorithms -to the design of robots, or parts of robots.  ...  The present review shows that, because evolutionary robotics experiments share common features, selective pressures for evolutionary robotics are a subject of research on their own.  ...  Combining novelty and objective-based search Novelty search can be combined with objective-based search thanks to multiobjective evolutionary algorithms: one objective is the traditional fitness function  ...
