Growth of self-canceling code in evolutionary systems

Xue Zhong, Terence Soule
2006 Proceedings of the 8th annual conference on Genetic and evolutionary computation - GECCO '06  
We find that allowing such 'canceling genes' leads to an overall increase in the rate of code growth, both through the inclusion of self-canceling code and through a general increase in introns.  ...  This research examines the behavior of inoperative code (introns) in the evolution of genetically robust solutions.  ...  CONCLUSION The results show that evolutionary systems will increase the overall amount of inoperative, but viable, code (represented in this research by pairs of genes whose effects cancel each other out  ...

Worm propagation and defense over hyperbolic graphs

E. Jonckheere
2004 2004 43rd IEEE Conference on Decision and Control (CDC) (IEEE Cat. No.04CH37601)  
The Cayley graphs of combinatorial group theory are used as prototypes of hyperbolic graphs.  ...  We investigate the speed of propagation of worms on the so-called δ-hyperbolic graphs, as defined by Gromov. Such graphs as the physical graph and the logical mail graph manifest this property.  ...  INTRODUCTION A worm can be defined to be a malicious piece of code that self-replicates as it self-propagates through a network by exploiting software vulnerabilities.  ...

Using Self-Adaptive Evolutionary Algorithms to Evolve Dynamism-Oriented Maps for a Real Time Strategy Game [chapter]

Raúl Lara-Cabrera, Carlos Cotta, Antonio J. Fernández-Leiva
2014 Lecture Notes in Computer Science  
This work presents a procedural content generation system that uses an evolutionary algorithm in order to generate interesting maps for a real-time strategy game, called Planet Wars.  ...  We use an evolutionary algorithm featuring self-adaptation of mutation parameters and variable-length chromosomes (which means maps of different sizes) to produce increasingly dynamic maps.  ...  In this case, both HI and LO reach their minimum at this 0.5 value. Evolutionary Approach We have used a self-adaptive evolutionary approach in order to optimize the dynamism of the generated maps.  ...
