Recently, many papers have proposed automatic techniques for · extraction of knowledge from numerical data. · minimization of the number of rules. But few works have been developed for design of experiments and datum plane covering. Most of optimization methods make the assumption that datum plane is sufficiently covered. If this assumption no longer holds, we will see that these methods may not work,...
Logistics center location is a key step of logistics system optimization, so it is important to select a proper method to assess it. First, the index system for location evaluation of logistics center is constructed by analyzing influencing factors of logistics center location. Then, the fuzzy matter-element model based on grey relevancy analysis is built in view of the fuzziness and incompatibility...
Partner selection is a classical combinatorial optimization problem. Its solution is a list of nodes which are the least value of each link. When the links and candidates are increased continuously, the complexity of partner selection grows exponentially. It is difficult to solve that problem in method of exhaustion. So this paper puts forward an improved algorithm, namely partner selection ant colony...
This paper presents a new technique to generate triangular mesh surface parameterization and characterize 3-D surfaces by invariant spherical harmonic shape descriptors of objects with spherical topology. First, the surface is initially parameterized by defining a continuous one-to-one mapping from the surface of the object to the surface of a unit sphere. Then, the initial parameterization is optimized...
