Topic of the Seminar

Recreational Computer Science

. . . from Langton’s Ant to Turing’s Subway inspired by recreational mathematics packages interesting topics in entertaining presentations wide range of topics

from theoretical computer science to algorithmic problems

easily understandable (popular science) introductions but scientific background

Example: Langton’s Ant

Very simple rules On white tile: paint tile black, turn 90◦ right, move one step forward On black tile: paint tile white, turn 90◦ left, move one step forward

Example: Langton’s Ant

Started on white plane builds several patterns in the first few hundred steps then very chaotic behaviour for a few thousand steps then building infinite “highway”

slide-6

Recreational Computer Science Organizational Matters Seminar Topics Next Steps

Example: Langton’s Ant

simple rules define really complex system seems to build a highway on all finite initial configurations but Turing-complete with infinite initial configurations Example of a cellular automaton
