查询词典 combinatorial analysis

Among them, one of the most promising seems to be Simulation Annealing that aims to reach the optimization of an objective function by physically analogizing to an annealing process of malerial at high temperature. This involves in a transformation of optimization of a function in continuous domain into a combinatorial optimization in discrete domain, as well as the proper choice of various control parameters such as temperature, iterative number etc.

In order to get out from the cockamamie work in road route design for designers, on the basis of studying the internal relations among local schemes, local scheme was decomposed to small unit logic schemes; the directed network was used to represent the topological connection; the united data structure of point-arc was used to express a network graph. Based on the shortest path theory, the combinatorial optimization algorithm that can search optimal logical schemes of some targets in the network graph intelligently and can form the whole scheme automatically was put forward.
