Rigorous Running Time Analysis of a Simple Immune-Based Multi-Objective Optimizer for Bi-Objective Pseudo-Boolean Functions

A simple immune-based multi-objective optimizer (IBMO) is proposed, and a rigorous running time analysis of IBMO on three proposed bi-objective pseudo-Boolean functions (Bi-Trap, Bi-Plateau and Bi-Jump) is presented. The running time of a global simple evolutionary multi-objective optimizer (GSEMO) using standard bit mutation operator with IBMO using somatic contiguous hypermutation (CHM) operator is compared with these three functions. The results show that the immune-based hypermutation can significantly beat standard bit mutation on some well-known multi-objective pseudo-Boolean functions. The proofs allow us to understand the relationship between the characteristics of the problems and the features of the algorithms more deeply. These analysis results also give us a good inspiration to analyze and design a bio-inspired search heuristics.     

高速公路施工区限速值分析

高速公路改扩建施工段合理的限速值是确保复杂环境下交通安全运行的重要因素。以驾驶员能接触到的各种不同信息出现的几率和出现量的大小为依据,将施工区道路几何信息、动态交通流信息、现场交通管制措施信息以及其它相关信息进行有机结合量化分析,为高速公路改扩建段的合理限速提供一定理论支持。
