Description

This is an experimental capability that allows the user to expose python algorithms to Dakota as top-level Iterators. The Dakota model is available to python and supplies function, gradient, and hessian responses as appropriate in addition to helper functions for model queries and output to the Dakota output stream.

The code example below shows class initialization which outputs the wrapped model ‘executor’ docstring.

Examples

import ext_method

class RandomSample:

    def __init__(self, executor, params_file=None):
        self.executor = executor
        help(self.executor)
