What (who) is zeroth-order approximation - definition
EXPRESSIONS FOR APPROXIMATION ACCURACY
First order approximation; Second order approximation; Zeroth order approximation; First-order approximation; Approximation order; Zero-order approximation; Degree of approximation; Degrees of approximation; 0th order approximation; Zeroth-order approximation; First approximation; Orders of approximation; First order of approximation; To a first approximation
to a first approximation
1. When one is doing certain numerical computations, an
approximate solution may be computed by any of several
heuristic methods, then refined to a final value. By using
the starting point of a first approximation of the answer, one
can write an algorithm that converges more quickly to the
correct result.
2. In jargon, a preface to any comment that indicates that the
comment is only approximately true. The remark "To a first
approximation, I feel good" might indicate that deeper
questioning would reveal that not all is perfect (e.g. a
nagging cough still remains after an illness).
