How Did I Spend My Time Growing Up? Legos Videogames

School Learn Computer Programming – Taught myself C/C++ in high school – Classes in web programming – Internships/Competitions Goal: Work on videogames? – Downloaded game design tools – Taught myself what I could

College: Undergraduate Formal Programming Experience – Put the “Science” in “Computer Science” – Learned about Data Structures, Algorithms, and Artificial Intelligence Independent Studies – Lego Robot – Research, Honors Thesis – Evolutionary Computation

College: PhD Student Current Research: Games and Evolution – Evolutionary Computation to get Intelligent Agents

What Is Evolution? Evolution: change in inherited characteristics of populations over successive generations ChildrenGrandchildren

What Is Evolution? Natural Selection: favorable traits become more common in populations when they increase reproductive success ChildrenGrandchildren

What Is Evolution? Evolution: change in inherited characteristics of populations over successive generations Natural Selection: favorable traits become more common in populations when they increase reproductive success – Populations produce more offspring than can survive – Individuals vary, affecting survival and reproduction – Traits are heritable
