Which one of the following best describes how Wang Tiles are visually modelled?

Question

BlackTom AI · Accepted Answer

Starting with what Wang Tiles are commonly described as in theory and visualization, the core idea is that each tile has colored edges that determine how tiles can fit together. 
Option 1: 'They are tiles with coloured edges' aligns exactly with the standard definition of Wang tiles, where edge colors constrain adjacency rules. This is the strongest and most accurate description. 
Option 2: 'They are black and white tiles arranged like a chess board' introduces a specific color pattern (black and white) and a chessboard arrangement, which is not how Wang tiles are defined; the formal concept uses colored edges, not fixed monochrome tiles or chessboard placement. 
Option 3: 'They are black tiles with white numbers' adds numerals and a color contrast that is not inherent to Wang tiles; the key feature is edge colors, not the tile body color or printed numbers. 
Option 4: 'They are white triangular tiles' changes both shape and color semantics; Wang tiles are typically square, not triangular, and the defining feature is edge colors rather than geometric shape or fill color. 
In sum, the distinguishing characteristic of Wang tiles is the use of colored edges to encode matching rules, which supports Option 1 as the correct conceptual description. The other options introduce specifics (board pattern, numbers, different shapes) that are not part of the standard Wang tile model.
