# Successive Tradeoff Methods

Robert P. Munafo, 1993 Jan 23.

Successive Tradeoff methods are one type of speed improvement (see that article for more).

A family of algorithms that facilitate compute-intensive imaging with an interactive user-interface. The common element of successive-tradeoff methods is to identify several alternative ways of generating an image, and to present each of those methods in succession, in order of increasing difficulty.

A successive tradeoffs method will work best if the successive image versions can be incrementally computed from one another: i.e., the work performed in generating the first version of the image can be used as a basis of computing the second version. The more work that can be re-used, the better. However, this is not essential: it is usually more important to present a "quick version" as soon as possible than to wait for a version in which the work can be re-used.

The following successive tradeoff methods are applicable to the generation of Mandelbrot images:

Successive Refinement (q.v.) in which the resolution of the image is gradually increased over time.

Automatic Dwell Limit (incremental method), in which the dwell limit is gradually increased over time.
