However, a choice of the fitness function is often intuitive. In this paper, an effective approach for a comparison of fitness function properties, which uses an estimation of fitness function landscape ruggedness, is described. Penalty coefficients define the importance of each parameter for design goal and change the difficulty of the fitness function landscape significantly. A reasonable choice of objectives and penalty coefficients allows us to reduce the computational efforts because of the smoother landscape of the fitness functions. The effectiveness of the approach is illustrated for fitness functions that are used for evolutionary antenna design.","PeriodicalId":134823,"journal":{"name":"NASA/DoD Conference on Evolvable Hardware, 2003.

Three different mechanisms of self-protection are considered and implemented on a cellular automata based evolutionary system, the evoloop. Simulation results imply a positive effect of those mechanisms on diversity maintenance, especially when the self-protection is moderate so that it conserves both the attacker and the attacked.","PeriodicalId":134823,"journal":{"name":"NASA/DoD Conference on Evolvable Hardware, 2003.

As a research platform we used the ATR's CAMBrain Machine (CBM). Reversible circuits are investigated because they are expected to dissipate much less energy than their irreversible counterparts. One day they will be implemented as nano-scale 3-dimensional chips. A circuit is reversible if the number of its inputs equals the number of its outputs and there is a one-to-one mapping between spaces of input vectors and output vectors. This paper provides: (1) a brief introduction to reversible logic concentrating on definitions and properties of the Feynman, Toffoli, Fredkin gates; (2) an introduction to the 3D cellular logic machine (CLM) that is a cellular automaton with frozen and pulsing state variables; and (3) a collection of reversible structures evolved using a dedicated GA and located in the CBM using the NeuroMaze 3.0 Pro, a software tool for computer-aided design of CBM-style structures.","PeriodicalId":134823,"journal":{"name":"NASA/DoD Conference on Evolvable Hardware, 2003.
