Distance Concentration-Based Artificial Immune Algorithm

The diversity, adaptation and memory of biological immune system attract much attention of researchers. Several optimal algorithms based on immune system have also been proposed up to now. The distance concentra- tion-based artificial immune algorithm (DCAIA) is proposed to overcome defects of the classical artificial immune al- gorithm (CAIA) in this paper. Compared with genetic algorithm (GA) and CAIA, DCAIA is good for solving the prob- lem of precocity,holding the diversity of antibody, and enhancing convergence rate.

浅谈保持“距离”的领导艺术

在领导活动中,领导者与领导者之间,领导者与被领导者之间,即“人我”关系之间的“距离”是一种客观存在。怎样与人相处,始终是需要领导者面对的一个十分重要的问题。我们党在领导中国革命和建设的事业中,科学、艺术地处理与同志、战友,与党外人士,与群众之间的关系,使人人都能积极、有效地处在同一动态的领导活动系统中,最大限度地挖掘其各自潜能、发挥其各自作用,对领导活动的目的和结果产生了重大影响。毛泽东同志保持“距离”的领导艺术,在革命和建设的实践中,炉火纯青,恰到好处的运用,已经成为各级领导干部的光辉典范,也是领导科学、领导艺术的基本原则和智慧的结晶,具有现实意义,值得我们认真地研究和学习。
