A navigation algorithm inspired by human navigation [PDF]
2012 IEEE/ACM International Conference on Advances in Social Networks Analysis and Mining, 2012 Human navigation has been a topic of interest in spatial cognition from the past few decades. It has been experimentally observed that humans accomplish the task of way-finding a destination in an unknown environment by recognizing landmarks. Investigations using network analytic techniques reveal that humans, when asked to way-find their destination ...
