Visual resolution and view-based navigation

For any organism there are increased metabolic costs that come with increased resolution within a sensory system.  This simple fact can precede a line of thought where one think there must be a trade-offs between the cost of increased sensory resolution and the inherent value that comes from a greater amount of information . In this paper we look at the performance of hypothetical agents performing view-based navigation. In simulation we vary the visual resolution of agents and measure the consequent navigation performance. The interesting thing is that agents with low resolution perform better than agents with high resolution when asked to recapitulate a visually defined route. This simple demo shows how the sensory systems of animals need not always be a trade-off of performance and utility.
