Fig. 8. Paths simulated by averaging weighted vectors. Insets show sets of simulated trajectories for food sites 45° apart (top left) and 90° apart (bottom right). The food was 100 cm from the start. Within each cluster, trajectories are shown for different weights of F2 (0 to 1 with increments of 0.2). The normalised headings of these trajectories after 80 cm are plotted. A normalised heading of 0 is directly toward F1 and a normalised heading of 1 is directly toward F2.
