The Objective Target Node identifies a numeric variable to minimize. The value is calculated using the following target function:
(x0-t0)^2 + (x1-t1)^2 + (x2-t2)^2 + ... + (xn-tn)^2
where xi is the i-th variable and ti the i-th target.
The function is equal to zero when every xi variable matches its ti target. This type of objective is well suited for error
minimization and system identification problems.
Configuring an objective node requires setting the following parameters:
Name: the name that will be used throughout modeFRONTIER to identify the objective. The name must be unique within the set of node names, and must follow the guidelines for node names.
Description: the node description will appear as tooltip when the mouse stop over the node in the Work Flow canvas.
Enabled: specifies whether the objective must be considered or ignored by scheduler algorithms.
Format: the numeric format that will be used in the various tables to display the value for the objective. The legal syntax for this parameter is described elsewhere (see Section 4.2.7, "Number Format Legal Syntax").
The data input connector can be connected to Input/Output Variable nodes. A target value must be defined for all the connected variables.
This node has no output.
Two error messages can be associated with an objective node:
| 180 | MISSING TARGET VALUE | No target has been provided for a given variable |
| 181 | MISSING OUTPUT TARGET | No targets has been specified for this node. |
