On a Conjecture of Micha
We prove a conjecture of Micha Perles concerning simple polytopes, for a subclass that properly contains the duals of stacked and crosspolytopes. As a consequence of a special property of this subclass it also follows that, the entire combinatorial structure of a polytope in the subclass can be recovered from its graph, by applying our results recursively.
متن کاملCOMPONENTS FOR IMMERSION Alexandre
A person is immersed when they feel part of an environment they experience and influence. While virtual immersion systems are usually designed on a case by case basis, and are not easily reusable or scalable, our goal is to specify and develop a framework for the design and integration of immersive systems. We address the issues raised in the design and implementation of the middleware componen...

This paper presents the Clustering Search (CS) as a new hybrid metaheuristic, which works in conjunction with other metaheuristics, managing the implementation of local search algorithms for optimization problems. Usually the local search is costly and should be used only in promising regions of the search space. The CS assists in the discovery of these regions by dividing the search space into...
متن کاملPEERS AT WORK Alexandre
We investigate how and why the productivity of a worker varies as a function of the productivity of her co-workers in a group production process. In theory, the introduction of a high productivity worker could lower the effort of incumbent workers because of free riding; or it could increase the effort of incumbent workers because of peer effects induced by social norms, social pressure, or lea...
متن کاملARRANGEMENTS Dan Halperin and Micha Sharir
Given a finite collection S of geometric objects such as hyperplanes or spheres in R , the arrangement A(S) is the decomposition of R into connected open cells of dimensions 0, 1, . . . , d induced by S. Besides being interesting in their own right, arrangements of hyperplanes have served as a unifying structure for many problems in discrete and computational geometry. With the recent advances ...
