Not really. There's a threshold where the outcome of an algorithm isn't predictable by the programmer. That threshold is much lower than mildly strong AI. As an example of a comparatively simple algorithm, Notch didn't know where the mountains, caves, oceans would be in the billions of Minecraft worlds - only some of their properties and distribution.
If AI programmers determined the AIs' decisions, that would negate the point of AI.
I can easily write a bunch of code you can't readily predict the outcome to but I can predict with 100% certainty. The easiest way is to cheat and inject code you don't readily see: http://c2.com/cgi/wiki?TheKenThompsonHack
