Escritoire/Reading/Revision_Function

The revision function is the method by which the post-ratings of cases and claim in an argument are adjusted taking account of the post-ratings of sub-arguments and cases (respectively) and prior-ratings.  The functions available are:

Rigid:  If the prior-rating is categorical (i.e. 0 or 1), the post-rating becomes the prior; If the prior-rating is undetermined (i.e. 0.5), the post-rating is the sub-argument post-rating; else a compromise between the prior and sub-argument post-rating rating is calculated.

Equitable:  The post-rating is calculated as the mean of the prior and sub-argument post-rating.

Flexible: The post is a compromise between the prior and sub-argument post-rating biased towards prior.  This is the default setting.

None:  No revision function is applied so the post becomes the sub-argument post-rating.

For further explanation of these options see Pacisco\Evaluative_Mechanism\Rationale
