meaning of wiggles

1. wiggles [scientific computation] In solving partial differential equations by finite difference and similar methods, wiggles are sawtooth up-down-up-down oscillations at the shortest wavelength representable on the grid. If an algorithm is unstable, this is often the most unstable waveform, so it grows to dominate the solution. Alternatively, stable though inaccurate wiggles can be generated near a discontinuity by a Gibbs phenomenon. wiki A collaborative web site comprised of the perpetual collective work of many authors. Similar to a web log in structure and logic, a wiki allows anyone, using a web browser, to edit, delete or modify content that has been placed on the web site including the work of other authors. In contrast, a blog, typically authored by an individual, does not allow visitors to change the original posted material, only add comments.
