If you have multiple survey ships near each other running on the automatic Survey command, they can head for the same anomaly. It would be better if each survey ship were aware of the destinations of the others, so that they could prioritize their anomaly destination choices to avoid redundancy. The ship that is closest to an anomaly should choose that anomaly; that ship is now assigned the job of surveying that anomaly. Next in priority is the ship that is closest to an anomaly that is not assigned to the first survey ship. Third in priority is the ship that is closest to an anomaly not claimed by the first two ships, and so on.
Likewise, I notice scout ships on automatic Explore can clump up instead of spreading out to explore different areas. Their missions should be aware of each other and prioritized to provide maximal exploration progress.
