| successive | 1. Following in order or in uninterrupted course; coming after without interruption or interval; following one after another in a line or series; consecutive; as, the successive revolution of years; the successive kings of Egypt; successive strokes of a hammer. "Send the successive ills through ages down." (Prior) 2. Having or giving the right of succeeding to an inheritance; inherited by succession; hereditary; as, a successive title; a successive empire. Successive induction. <mathematics> See Induction. Origin: Cf. F. Successif. See Succeed. Source: Websters Dictionary (01 Mar 1998) |

| successive contrast | The visual effect caused by viewing a brightly coloured object and then a gray surface; the latter appears tinged with the complementary colour of the object. Viewing a surface coloured in the complementary colour of the object rather than in gray enhances the colour intensity of the surface. (05 Mar 2000) |
| approximation | 1. The act of approximating; a drawing, advancing or being near; approach; also, the result of approximating. "The largest capacity and the most noble dispositions are but an approximation to the proper standard and true symmetry of human nature." (I. Taylor) 2. An approach to a correct estimate, calculation, or conception, or to a given quantity, quality, etc. 3. <mathematics> A continual approach or coming nearer to a result; as, to solve an equation by approximation. A value that is nearly but not exactly correct. Origin: Cf. F. Approximation, LL. Approximatio. Source: Websters Dictionary (01 Mar 1998) |
| approximation suture | A suture that pulls together the deep tissues. (05 Mar 2000) |
| Hartree-Fock approximation | <radiobiology> A refinement of the Hartree method in which one uses determinants of single-particle wave functions rather than products, thereby introducing exchange terms into the Hamiltonian. (06 Mar 1998) |
| successive approximation |
The iterative scheme by which an approximation is used for the basic design of an algorithm. The sequence generated is of the form x^(k+1) = x^k + A(x^k), where A is an algorithm map specified by its approximation to some underlying goal. Typically, this is used to find a fixed point, where A(x)=0 (eg, seeking f(x)=x, let A(x) = f(x) - x, so the iterations are x^(k+1) = f(x^k), converging to x*=f(x*) if f satisfies certain conditions, such as a contraction map).

Alternatively known as Successive Approximation Character Weighting (SACW). This is a method of reweighting characters based on some measure of their relative values for the purposes of phylogeny reconstruction. If, for instance, an initial analysis is carried out and the result of this analysis indicates that some characters are quite inconsistent with the resulting tree(s), then these will be down-weighted in subsequent analyses. ...
