Robustness and Adaptiveness Analysis of Future Fleets
Slawomir Wesolkowski, Michael Mazurek, James M. Whitacre +2
Making decisions about the structure of a future military fleet is a challenging task. Several issues need to be considered such as the existence of multiple competing objectives a…
Network Topology and Time Criticality Effects in the Modularised Fleet Mix Problem
James M. Whitacre, Axel Bender, Stephen Baker +3
In this paper, we explore the interplay between network topology and time criticality in a military logistics system. A general goal of this work (and previous work) is to evaluate…
Use of statistical outlier detection method in adaptive evolutionary algorithms
James M. Whitacre, Tuan Q. Pham, Ruhul A. Sarker
In this paper, the issue of adapting probabilities for Evolutionary Algorithm (EA) search operators is revisited. A framework is devised for distinguishing between measurements of…
Computational Scenario-based Capability Planning
Hussein Abbass, Axel Bender, Helen Dam +3
Scenarios are pen-pictures of plausible futures, used for strategic planning. The aim of this investigation is to expand the horizon of scenario-based planning through computationa…
Adaptation and Self-Organization in Evolutionary Algorithms
James M Whitacre
Abbreviated Abstract: The objective of Evolutionary Computation is to solve practical problems (e.g. optimization, data mining) by simulating the mechanisms of natural evolution. T…
Strategic Positioning in Tactical Scenario Planning
James M. Whitacre, Hussein A. Abbass, Ruhul Sarker +2
Capability planning problems are pervasive throughout many areas of human interest with prominent examples found in defense and security. Planning provides a unique context for opt…
The Self-Organization of Interaction Networks for Nature-Inspired Optimization
James M. Whitacre, Ruhul A. Sarker, Q. Tuan Pham
Over the last decade, significant progress has been made in understanding complex biological systems, however there have been few attempts at incorporating this knowledge into natu…
Evidence of coevolution in multi-objective evolutionary algorithms
James M Whitacre
This paper demonstrates that simple yet important characteristics of coevolution can occur in evolutionary algorithms when only a few conditions are met. We find that interaction-b…
Degenerate neutrality creates evolvable fitness landscapes
James M Whitacre, Axel Bender
Understanding how systems can be designed to be evolvable is fundamental to research in optimization, evolution, and complex systems science. Many researchers have thus recognized…
Spontaneous organization leads to robustness in evolutionary algorithms
James M. Whitacre, Ruhul A. Sarker, Q. Tuan Pham
The interaction networks of biological systems are known to take on several non-random structural properties, some of which are believed to positively influence system robustness.…
Survival of the flexible: explaining the recent dominance of nature-inspired optimization within a rapidly evolving world
James M Whitacre
Although researchers often comment on the rising popularity of nature-inspired meta-heuristics (NIM), there has been a paucity of data to directly support the claim that NIM are gr…
