chimera_elimination_order(m, n=None, t=None)[source]

Provides a variable elimination order for a Chimera graph.

A graph defined by chimera_graph(m,n,t) has treewidth $$max(m,n)*t$$. This function outputs a variable elimination order inducing a tree decomposition of that width.

Parameters: m (int) – Number of rows in the Chimera lattice. n (int (optional, default m)) – Number of columns in the Chimera lattice. t (int (optional, default 4)) – Size of the shore within each Chimera tile. order – An elimination order that induces the treewidth of chimera_graph(m,n,t). list

Examples

>>> G = dnx.chimera_elimination_order(1, 1, 4)  # a single Chimera tile
