term -- An rpn expression giving one term to be optimized.
If more than one optimization_term command is given, then the terms are
added. The advantage of using this command over giving an equation via
optimization_setup is that elegant will report the value of
each term as it performs the optimization (if a log_file is 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_string, field_initial_value, field_final_value, 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 Cx to 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_file, input_column -- If given, input_file is 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.
