چکیده

Given a set of entities, Cluster Analysis aims at finding subsets, called clusters, which are homogeneous and/or well separated. As many types of clustering and criteria for homogeneity or separation are of interest, this is a vast field. A survey is given from a mathematical programming viewpoint. Steps of a clustering study, types of clustering and criteria are discussed. Then algorithms for hierarchical, partitioning, sequential, and additive clustering are studied. Emphasis is on solution methods, i.e., dynamic programming, graph theoretical algorithms, branch-and-bound, cutting planes, column generation and heuristics. Résumé Étant donné un ensemble d’objets, la classification automatique a pour but de trouver des sous-ensembles, ou classes, homogènes et/ou bien séparées. Comme de nombreux types de classification et critères d’homogénéité et de séparation sont dignes d’intéret, ce domaine est varié. On en présente une revue, d’un point de vue de programmation mathématique. On discute les étapes d’une étude de classification, les types de classigication et les critères. On étudie ensuite les algorithmes de classification hiérarchique, de partitionnement, de classification séquentielle et additive. On insiste sur les méthodes de résolution, c’est-à-dire la programmation dynamique, les algorithmes de graphes, les procédures d’optimisation par séparation, la génération de colonnes et les heuristiques.

State-of-the-art survey to be presented at the XVIth Mathematical Programming Symposium, Lausanne August 25–29 1997, to appear in Mathematical Programming, B.

A Mathematical Optimization Model for Solving Minimum Ordering Problem with Constraint Analysis and some Generalizations

In this paper, a mathematical method is proposed to formulate a generalized ordering problem. This model is formed as a linear optimization model in which some variables are binary. The constraints of the problem have been analyzed with the emphasis on the assessment of their importance in the formulation. On the one hand, these constraints enforce conditions on an arbitrary subgraph and then g...
