term-- An rpn expression giving one term to be optimized. If more than one
optimization_termcommand is given, then the terms are added. The advantage of using this command over giving an equation via
optimization_setupis that elegant will report the value of each term as it performs the optimization (if a
log_fileis given to
optimization_setup). This permits determination of which terms are causing problems for the optimization.
Please see the entry for equation under optimization_setup for details on designing optimization terms.
weight-- The weight to assign to this term. If zero, the term is ignored.
field_interval-- These parameters are used to perform substitution of a series of values into the string given by
term. This can be used to make an identical constraint at a number of instances of the same marker. For example, to constraint
Cxto zero at instances 1, 3, 5, ..., 39, of marker
M1, one could use
&optimization_term term = "M1#@.Cx sqr", field_string = @, field_initial_value = 1, field_final_value = 39, field_interval = 2 &end
input_column-- If given,
input_fileis taken as the name of an SDDS file, which is expected to have a string column named by
input_column. Each row of the column is taken as a separate optimization term.
verbose-- If nonzero, optimization terms are echoed to the terminal as they are created or read from the input file.
