solving processes are applicable:
• A form of means-ends reasoning, where the differences are "reduced" in
order of most to least significant.
• A kind of hill-climbing method of design modification, where parameters
are changed, direction of improvement noted, and additional changes are
made in the direction of maximal increment in some measure of overall
performance. This form can even constitute the only method of design in
some domains: heuhstically assign initial values to the parameters, and
change them in a hill-climbing fashion until a maximum is reached, and
deliver that as the design. This is especially applicable where the desig
