Switching goals
Date:8/27/2007

odeling. They theorized that the forces acting on evolution may be modular as well, and for each goal, they defined subgoals that could each change in relation to the others. 'In an organism, for example, you might classify these subgoals as the need to eat, the need to keep from being eaten, and the need to reproduce. The same subgoals must be fulfilled in each new environment, but there are differences in nuance and combination,' says Kashtan. 'We saw a large speedup, for instance, when we repeatedly exchanged an 'OR' for an 'AND' in the computer code defining our goals, thus changing the relationship between subgoals.'

Although the main aim of this research, which appeared recently in the Proceedings of the National Academy of Sciences (PNAS), was to shed light on theoretical questions of evolution, it may have some practical implications, particularly in engineering fields in which evolutionary tools are commonly used for systems design; and in computer science, by providing a possible way to accelerate optimization algorithms.
