pebbling

The pebbling causes the rock to rotate and curve as it slides.

But when at last Kirk felt sensation return to him, all he could see on his skin was a faint pebbling of tiny scars.

The game of pebbling was first suggested by Lagarias and Saks, as a tool for solving a particular problem in number theory.

Graph pebbling is a mathematical game and area of interest played on a graph with pebbles on the vertices.

The goal remains to place a black pebble on the target vertex, but the pebbling of adjacent vertices may be done with pebbles of either color.

One of the central questions of graph pebbling is the value of π(G) for a given graph G.

A extension of "Black Pebbling", known as "Black-White Pebbling" was developed by Stephen Cook and Ravi Sethi in a 1976 paper.

Other topics in pebbling include cover pebbling, optimal pebbling, domination cover pebbling, bounds, and thresholds for pebbling numbers, deep graphs, and others.
