A method can include receiving an initial waveform and generating, testing, and evaluating the performance of an initial child set of waveforms based on an initial parent set of waveforms from the initial waveform. The method can also include determining whether a termination condition has been met based on the evaluating and, if so, providing an optimized waveform. If the termination condition has not been met, the method can also include generating subsequent child sets of waveforms based on the previous child set(s).
