Web3 jun. 2024 · It requires, that the grid (graph) is represented as a dictionary where the keys are point (node) coordinates on the grid and the values are neighbouring points to which an outgoing arrow (edge) should be drawn. When the size of your grid changes, you will probably need to play around with w, h and such to control the size of the plotted elements.

A lattice is an abstract structure studied in the mathematical subdisciplines of order theory and abstract algebra. It consists of a partially ordered set in which every pair of elements has a unique supremum (also called a least upper bound or join) and a unique infimum (also called a greatest lower bound or meet). An example is given by the power set of a set, partially ordered by inclusion, for which the supremum is the union and the infimum is the intersection. Another example is give… WebBook Title: General Lattice Theory. Book Subtitle: Second edition. Authors: George Grätzer.
