Approximation
(gcide) | Approximation \Ap*prox`i*ma"tion\ n. [Cf. F. approximation, LL.
approximatio.]
1. The act of approximating; a drawing, advancing or being
near; approach; also, the result of approximating.
[1913 Webster]
The largest capacity and the most noble dispositions
are but an approximation to the proper standard and
true symmetry of human nature. --I. Taylor.
[1913 Webster]
2. An approach to a correct estimate, calculation, or
conception, or to a given quantity, quality, etc.
[1913 Webster]
3. (Math.)
(a) A continual approach or coming nearer to a result; as,
to solve an equation by approximation.
(b) A value that is nearly but not exactly correct.
[1913 Webster] |
approximation
(wn) | approximation
n 1: an approximate calculation of quantity or degree or worth;
"an estimate of what it would cost"; "a rough idea how long
it would take" [syn: estimate, estimation,
approximation, idea]
2: the quality of coming near to identity (especially close in
quantity)
3: an imprecise or incomplete account; "newspapers gave only an
approximation of the actual events"
4: the act of bringing near or bringing together especially the
cut edges of tissue [syn: approximation, {bringing close
together}] |

approximation algorithm
(foldoc) | approximation algorithm
An algorithm for an optimisation problem that
generates feasible but not necessarily optimal solutions.
Unlike "heuristic", the term "approximation algorithm" often
implies some proven worst or average case bound on
performance. The terms are often used interchangeably
however.

to a first approximation
(foldoc) | 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).

to a zeroth approximation
(foldoc) | to a zeroth approximation
(From "to a first approximation") A *really* sloppy
approximation; a wild guess.
Compare social science number.
