Burden and Benefits of Redundancy

چکیده
This work investigates the effects of two techniques introducing redundancy, diploid representations and decoders. The effects of redundancy on mutation, recombination, the structure of the landscape and the interplay between these ingredients are of particular interest. Resulting neutral mutations are found to be the reason for the transformation of local optima into plateau points. Additional neutral recombinations enable a more efficient search on those neutral plateaus. Furthermore, both kinds of neutral operations are shown to have a positive impact on the diversity of the population over time. Lastly, the diploid representation is compared empirically to a macromutation which models the working principles of diploidity. However, this control experiment shows that blind exploring mutations cannote approximate diploidity.

Reliability Optimization for Complicated Systems with a Choice of Redundancy Strategies (TECHNICAL NOTE)
Redundancy allocation is one of the common techniques to increase the reliability of the bridge systems. Many studies on the general redundancy allocation problems assume that the redundancy strategy for each subsystem is predetermined and fixed. In general, active redundancy has received more attention in the past. However, in real world, a particular system design contains both active and col...
متن کاملA redundancy allocation problem with the choice of redundancy strategies by a memetic algorithm
This paper proposes an efficient algorithm based on memetic algorithm (MA) for a redundancy allocation problem without component mixing (RAPCM) in a series-parallel system when the redundancy strategy can be chosen for individual subsystems. Majority of the solution methods for the general RAPCM assume that the type of a redundancy strategy for each subsystem is pre-determined and known a prior...

متن کاملA New Nonlinear Multi-objective Redundancy Allocation Model with the Choice of Redundancy Strategy Solved by the Compromise Programming Approach
One of the primary concerns in any system design problem is to prepare a highly reliable system with minimum cost. One way to increase the reliability of systems is to use redundancy in different forms such as active or standby. In this paper, a new nonlinear multi- objective integer programming model with the choice of redundancy strategy and component type is developed where standby strategy ...
