As software systems grow in size and complexity, so does the di culty of understanding and maintaining them. Research in software understanding attempts to mitigate this problem by making various aspects of software development more visible, accessible, and comprehensible.

Identifying food-conditioned bears may be difficult if the animal is not captured or killed while immediately engaged in the nuisance behavior. Fatty acid signature analysis has been used to examine the dietary habits of bears and ...
