Representing Hypothesis

Hypotheses in GA are binary strings.
They can be tricky to generate.
For example, if Outlook can be either Sunny, Overcast, or rain, and Wind can be Strong or Weak, how do re represent \[ (Outlook = Overcast \vee Rain) \wedge (Wind = Strong) \] With something like

Outlook Wind

011 10
We can then use this as rule preconditions. For example the rule

IF Wind = Strong THEN PlayTennis = yes

can be represented with the string

Outlook Wind PlayTennis

111 10 10
