Seurat completed the painting of Bathers at Asnières in 1884, at 24 years old. He applied to the jury of the Salon of the same year to have the work exhibited there, only to be rejected. The Bathers continued to puzzle many of Seurat’s contemporaries, and the picture would only be widely acclaimed many years after the artist's death (age 31).
Graph-based model s: a clique, that is, a subset of nodes in a graph such that every two nodes in the subset are connected by an edge can be considered as a prototypical form of cluster. Relaxations of the complete connectivity requirement (a fraction of the edges can be missing) are known as quasi-cliques, as in the HCS clustering algorithm .
A sequence enumerating all positive rational numbers.Each positive real number is a cluster point.. Let be a subset of a topological space. A point in is a limit point or cluster point or accumulation point of the set if every neighbourhood of contains at least one point of different from itself.
Portrait of Seurat by Maximilien Luce. This is a list of notable paintings by Georges Seurat (2 December 1859 - 29 March 1891). He is a Neo-Impressionist painter and together with Paul Signac noted for being the inventor of pointillism. [1] The listing follows the 1980 book Georges Seurat and uses its catalogue numbers. [2]
The average silhouette of the data is another useful criterion for assessing the natural number of clusters. The silhouette of a data instance is a measure of how closely it is matched to data within its cluster and how loosely it is matched to data of the neighboring cluster, i.e., the cluster whose average distance from the datum is lowest.

The standard algorithm for hierarchical agglomerative clustering (HAC) has a time complexity of () and requires () memory, which makes it too slow for even medium data sets. . However, for some special cases, optimal efficient agglomerative methods (of complexity ()) are known: SLINK [2] for single-linkage and CLINK [3] for complete-linkage clusteri
Seurat was born on 2 December 1859 in Paris, at 60 rue de Bondy (now rue René Boulanger). The Seurat family moved to 136 boulevard de Magenta (now 110 boulevard de Magenta) in 1862 or 1863. [9]
The multiple subset sum problem is an optimization problem in computer science and operations research. It is a generalization of the subset sum problem. The input to the problem is a multiset of n integers and a positive integer m representing the number of subsets. The goal is to construct, from the input integers, some m subsets. The problem ...
