In cellular automata, the **Moore neighborhood** comprises the eight cells surrounding a central cell on a two-dimensional square lattice. The neighborhood is named after Edward F. Moore, a pioneer of cellular automata theory. It is one of the two most commonly used neighborhood types, the other one being the 4-cell von Neumann neighborhood. The well known Conway's Game of Life, for example, uses the Moore neighborhood. It is similar to the notion of 8-connected pixels in computer graphics.

The concept can be extended to higher dimensions, for example forming a 26-cell cubic neighborhood for a cellular automaton in three dimensions.

The Moore neighbourhood of a point is the points at a Chebyshev distance of 1.

The number of cells in a Moore neighbourhood, given its range *r*, is the odd squares: (2*r* + 1)2.

### Famous quotes containing the words neighborhood and/or moore:

“Almost everybody in the *neighborhood* had “troubles,” frankly localized and specified; but only the chosen had “complications.” To have them was in itself a distinction, though it was also, in most cases, a death warrant. People struggled on for years with “troubles,” but they almost always succumbed to “complications.””

—Edith Wharton (1862–1937)

“Hindered characters

seldom have mothers

in Irish stories, but they all have grandmothers.”

—Marianne *Moore* (1887–1972)
