dc.description.abstract | Worms create complex paths when moving through sediment to feed. This research applies computer simulation models to provide a unique approach to visualise and quantify the process by which complex worm paths can emerge from simple local movement decisions. A grid environment is proposed in which worms can move with choice of up to 8 directions at each step. This uses a square grid with diagonal paths which has not been investigated before and the resulting number of complex paths is increased compared to triangular grids. Results identify many novel worm paths. Some of the resulting paths are symmetrical, others produce repetitive looping paths, others return to the origin. Interesting worm paths are identified with chaotic movement. Some include oscillating between chaotic and ordered movement for which the outcome is still unknown after millions of steps. A conclusion that may be extrapolated to other creatures is that local movement decisions of a species substantially determine the overall global search strategy that emerges. | en_GB |

dc.description | Data availability: All of the worm codes for the worms shown in the figures of this paper are included within this paper. A collection of worm images and log files has been exported and is available from the author. This includes a set of worm path images for all worms up to a code length of 11. Log files from the random and recursive runs are available, enabling analysis of the categories of worm in both scenarios. | en_GB |
