CMP.8:10 - Architectural Rationale

An adjustable approximation joins a mathematical comparison to an effective algorithm. Convergence alone supplies no running procedure; a fast procedure alone supplies no relation to the desired answer. Keeping obtaining, loss, representation and use together makes each approximation step inspectable and replaceable.

Feasibility, accuracy and the receiver’s decision are separate obligations because one can survive while another fails. The same distinction permits composition with relaxation, iterative updates, probabilistic estimation and subject modeling without imposing one error measure on all of them.
