AI Programming for Decision Matrix Evaluation Theory; Case Study by Lance Winslow
When programming artificial intelligent systems to make decisions and or evaluate there are a number of theories that should be explored before choosing a specific path. Writing code is tedious and time consuming indeed and it is appropriate to do as much up front work as possible. ... Using techniques of double or triple elimination you can better evaluate and remove much of the randomness of chance or luck and improve probability for coming up with not necessarily the absolute answer, but statistically speaking the best probable answer down to a point in which you can feel good that your...
