A special class of EVE objects has been defined that encapsulates an optimization task, presenting the initial values for the optimizer run as control variables to the outside world. In a fashion similar to the previous section, initial values are accessed by names constructed from the names of the variables they correspond to. For instance, if the system to be optimized has a parameter alpha, the corresponding initial value is accessible as alpha-init. As a response, the optimum found by the optimizer is returned. Communication with the external optimizer executable is taken care of by tool agent as described in Section 3.5.1. Figure 8.9 shows an optimizer working on an RSM model. The initial values of the optimization loop are available as control variables in the OPT EVE.
