Previous work investigating the performance of genetic algorithms (GAs) has attempted to develop a set of fitness landscapes, called “Royal Roads” functions, which should be ideally suited for search with GAs. Surprisingly, many studies have shown that genetic algorithms actually perform worse than random mutation hill-climbing on these landscapes, and several different explanations have been o...

We automate the organization of GPS data to create a visibility map with correctly connected intersections. For our example case study, we use GPS data collected on the Swarthmore College campus. After the data is automatically organized and cleaned, a user is able to select points on a visual map to search for an optimal path between those points. 1 The Problem of Navigation Swarthmore College...

Not surprisingly, most research on the neurobiology of language has focused on language itself. Yet even after decades of investigation, we know much less about the neurobiological correlates of language than we do about the neurobiology of many other domains, such as vision, motor function, and memory. This relative lack of progress is likely due not only to the complexity of language and to a...
