That's very different from changing ones approach to a problem after learning more about it, and as events change the situation. Except that, in many instances of Trump's....evolving...positions, he has changed his mind (or stated conflicting positions on an issue) within the SAME interview or speech.
Trump is not using a teleprompter. It's kind of like brainstorming. Until he settles on an action, nothing is carved in stone.
That's Creative Problem Solving.
