An Investigation of the Importance of Mechanisms and Parameters in a Multicellular Developmental System

Abstract

Abstract-Multicellular organisms in biology possess invaluable characteristics, which artificial systems in engineering lack, such as adaptivity and robustness. Modeling biologically inspired multicellular developmental systems in evolutionary computation have been considered for a number of years, and there exist many developmental simulations that capture multicellular characteristics of biological organisms. However, the relative importance of many mechanisms in such models is still poorly understood. This paper undertakes a detailed investigation of the importance of many mechanisms and parameters on the organizational behavior of a gene regulatory network based artificial developmental system via classical pattern matching experiments. The work leads to an improved understanding of artificial multicellular development, which will assist in its utilization in the application of evolutionary computation. It may also provide a better understanding of mechanisms of biological development.

Embedded Social Insect-Inspired Intelligence Networks for System-level Runtime Management

“…There are many examples of large complex systems in Nature that exhibit both the the scalability and collective co-ordination that are required for large many-core systems. From the molecular interactions of gene regulatory networks driving development of multi-cellular structures [5], [6], to the chemical signalling between bacteria in a Protoza society [7] and complex systematics of colonial organisms in a Hydrozoa consisting of many sub-organisms [8]; often these natural systems exhibit highly scalable development and maintenance abilities for solving a particular set of actions for survival in a number of challenging environments.…”

Optimal Design of Rectification Circuit in Electronic Circuit Fault Self‐repair Based on EHW and RBT

“…At present, some new fault self-repair technologies are put forward, for example, reconfigurable technology [7,8] , embryonic circuit technology [9,10] , and conventional Evolvable hardware (EHW) technology [11−15] . However, the reconfigurable technology has limited fault-tolerant capability, low redundant resource utilization rate, and great hardware resource cost, which cannot easily meet the requirements of high reliability, light weight, and low cost of the fault-tolerant system [7,8] .…”

“…In addition, since self-repair is mainly aimed at FPGA programmable chips, extensive application of reconfigurable technology to fault self-repair of electronic circuits is directly limited. Embryonic circuit is novel in theory but it is still under theoretical research and embryonic circuit design, and unified circuit hardware standard and self-repair technology standard are not formed, so it is hard to achieve wide engineering application [9,10] . The conventional EHW technology is mainly applied to circuit evolution and reconfigurable chip, etc., but fault self-repair of EHW-based electronic circuit is a new field, of which the application research is still characterized with slow circuit evolution, low convergence precision, great hardware resource consumption, and limited self-repair application scope, etc [12−15] .…”
