Tau's Pointwise Revision: Dynamic Software Updates Explained

[S1r_4zdr3w(OP)]

Pointwise Revision is a crucial mechanism within the Tau Language that enables software updates and self-amendment without requiring the entire program or specification to be rewritten from scratch. It works by logically combining new requirements with existing ones, prioritizing outputs that satisfy both the old and new specifications, and falling back to only the new if there's a contradiction, thereby ensuring maximal preservation of the previous behavior. This algorithm solves the general "belief revision" problem in the context of Tau's software specification language, which is otherwise considered unsolvable.
