Day 17 & 18

Day 17 was an off day for work reasons. Day 18 is mostly spent looking at lecture on the topic. The Game AI Pro's chapter on Utility Theory might have some clues. From what I read it sounds like it describes what I'm stuck on: figuring how from a field of values I can determine a strict evaluable single field. I still wonder how I can cut down the crust I built with the current AI experimentation and start from a saner base. What to keep, what to yield.
Edit: Let's be honest, I'm becoming frustrated with the way I'm stuck and this is chipping away my willingness to work into that task. I hope that browsing that book will rekindle my curiosity and make me want to give a shot to other stuff.
