Abstract
We prove that the accumulation points of a sequence of graphs with respect to the cut-distance are exactly the weak limit points of subsequences of the adjacency matrices (when all possible orders of the vertices are considered) that minimize the entropy over all weak limit points of the corresponding subsequence. In fact, the entropy can be replaced by any map , where is a continuous and strictly concave function. Our proofs are elementary, and do not use the regularity lemma.
