We went over the Assignment Specs

Alpha-Beta Pruning

Root Node: Initially our minimum value is neg-infinity. Our max value is infinity

keep going down each node having -+infin until we hit leafs

When we hit our first leaf (assume parent is maxinode) the value of Alpha is set, and we set for each leaf. ... our alpha and beta will be exactly the same for the first pass [6,6]

When you walk up from this, (now at a mininode) alpha beta of this node is [neginfi,6] we walk down (maxinode to leaf) to the very first leaf and see that the value is 8, this means that at a minimum our maxinode will be 8... it might be more, but it doesn't matter at this point.

describing w/o pictures is very difficult.
