Syntax: MERIT <expression> OR

 

PENALTY <expression>

 

Example: PENALTY 100*(OutputFlux/InputFlux - 1)

PARAMETERS

Defines quantities to guide the optimizer. The number of function

 

evaluations (i.e., tempest runs) per restart will not exceed iterations,

 

convergence will be declared when the penalty function value in all

 

the simplex points is within tolerance of the best value, and the

 

optimizer will be restarted restarts times after converging or running

 

out of iterations.

 

Parameters: iterations tolerance restarts

 

Example:

 

PARAMETERS iterations=35 tolerance = 1e-3 restarts = 2

3.1.11. SCHEDULE Group

Stepping is not implemented in this release.

VARIABLES

Tell the stepper which variables to step. These must have been

 

defined in a SET statement.

 

Syntax: VARIABLES var1 ... varN

RANGE

Tell the stepper how far, and at what intervals, to step variable

 

varname.

 

Parameters: varname lo hi stepsize

STORE

Supply a file name for the stepper’s results.

 

Syntax: STORE <filename>
