Hard-Wired Neural Networks

Consider the task of adjusting several interdependent parameters of a complex system so that its output function is optimal. An example is scheduling classes at a large university, so that conflicts among classroom use, student course choices, and faculty teaching times are minimized. Another is the simultaneous function of the many muscles in the human body in performing a complex task like riding a bicycle or juggling. For a task with multiple simultaneous constraints among the variables, it is often impossible to find a solution that is guaranteed to be optimal (as in, the absolute best). But there are several approaches to finding very good solutions, and for many real-world situations this is sufficient.

A neural network can be designed to approach such a problem by defining each unit to represent the "truth value" of a specific hypothesis. For example, in the class-scheduling task...
