Node
From Sudopedia, the Free Sudoku Reference Guide
Jump to navigationJump to searchA node is an item in a chain or loop. It can be a cell, a candidate or a complex structure like an Almost Locked Set.
The term vertex (in plural form: vertices or vertexes), coming from the field of geometry, is sometimes used as an alias.
The nodes are connected with links, or in geometry: lines or edges.
