图染色问题

各位大侠，我现在在看一个关于多约束组合优化问题的论文，很多看不懂的，请帮忙翻译下： 1.Since the number of two-element to five-element subsets of a reference set, for example, can be quite large, even a highly selective process for isolating preferred instances of these subsets as a basis for generating combined solutions can produce a significant number of combinations, and so there is a practical need for keeping the cardinality of the set small。 2.The approach was motivated by the supposition that information about the relative desirability of alternative choices is captured in different forms by different rules, and that this information can be exploited more effectively when integrated by means of a combination mechanism than when treated by the standard strategy of selecting different rules one at a time, in isolation from each other. In addition, the method departed from the customary approach of stopping upon reaching a local optimum, and instead continued to vary the parameters that determined the combined rules, as a basis for producing additional trial solutions. 谢 |
