No. Adjusting a rule is entirely different from adjusting a number. The adjustment of a number merely explores a space. A number spectrum does specify/describe a metric. So, for example, adjusting an integer with particular boundaries for the model, say [-10, 100] provides a well-defined space. The adjustment of a rule, however, doesn't _necessarily_ assume any such space or metric, which is why we have to back off to the more flexible word "measure". The methods used for search and optimization are different when exploring ill-formed "spaces" versus well-formed spaces. And it's important to point this out in order to be clear about one's research, especially to an audience that may not be expert in modeling and simulation. - -- glen e. p. ropella, 971-219-3846, http://tempusdictum.com I have the heart of a child.
