PPT-Decision Trees and Tables

2 Decision Trees and Decision Tables Often our problem solutions require decisions to be made according to two or more conditions or combinations of conditions Decision trees represent such decision as a sequence of steps. In Section 4 of this Appendix the tables are carried out to a large number of decimal places and exact values are indicated by underlining In most of the other tables only a limited number of decimal places are given therefore making the tables bett T state 8712X action or input 8712U uncertainty or disturbance 8712W dynamics functions XUW8594X w w are independent RVs variation state dependent input space 8712U 8838U is set of allowed actions in state at time brPage 5br Policy action is function Psychology of Personal Decision-Making.
