Additionally, as precautionary measure, if the ACSA generates a cuckoo egg that falls outside the domain of interest, its position will remain unchanged. Conclusions In this paper, by scrutinizing the advantages and the limitations of the standard CSA, a new modified CSA, specifically the ACSA, which adopts an adjustable step size in its computation, has been proposed. Genetic algorithms and simulated annealing, On the other hand, the proposed ACSA is getting closer to the global optima as the iteration increases gradually.

The results are presented in the last column of Table 1. For such incidents, the host bird will either evict the parasitic egg or abandon the nest totally and seek for a new site to rebuild the nest. They mimic the colour and pattern of the host eggshell in order to disguise their eggs from being detected by the host birds. Although finding this valley is not tedious, reaching the global optima is difficult [ 24 ].

Wireless sensor network localization based on cuckoo search algorithm. In fact, as shown in Table 2the DE, EP, and PSO algorithms usually converge faster initially, but they often get stuck in local optima easily, which is particularly obvious in the case of Ackley, de Jong, and Griewank’s functions.

For each test function, the initial populations of 20 host nests are generated randomly. The 3-dimensional surface plot for the Rosenbrock’s function.


Adaptive Cuckoo Search Algorithm for Unconstrained Optimization

Performance Comparison with Other Optimization Algorithms In comparing the performances of different algorithms in optimizing the same benchmark functions, several ways with different stopping criteria can be considered, in which comparison of best fitness value for a fixed number of fitness function evaluations, a commonly used approach, has been adopted in this study.

The CSA, which draws inspiration from cuckoo’s adaption to breeding and reproduction, is idealized with the assumptions zckley follows:. The GDD can be used under the big valley structure. Automatic method for finding the greatest or optimuzation value of a function. Thus, the fraction of nests to desert p a is assigned as 0.

Adaptive Cuckoo Search Algorithm for Unconstrained Optimization

In this fynction work, a new adaptive cuckoo search algorithm ACSA is presented. However, the MGG is not suited for multi-parental crossovers. This is the region where the global minimum is resided. Performance comparison of ACSA with other optimization methods in terms of fixed iteration number.

Finally, some conclusions are drawn in Section 5. Numerical Simulations To evaluate the feasibility of the proposed ACSA, the algorithm is applied to optimize the five benchmark functions with known global vecto, where two of which are unimodal and three of which are multimodal.

In addition, to authenticate the statistical significance of the proposed ACSA, the two-tailed t -test is applied. New articles by this author.

The average of the distance difference for each loop from all the 30 trials is then measured. Advances in neural information processing systems 2, Proceedings of the Genetic and Evolutionary Computation Conference, vectpr, However, the relationship between the host species and the cuckoos is often a continuous arms race. Only the fittest among all the host nests with high quality eggs will be passed on to the next generation. Goyal S, Patterh Acckley.

The obtained average best fitness values at fixed iteration number of 1,and in optimizing the benchmark functions are summarized in Table 2. ABC has been developed by being inspired foraging and waggle dance behaviors of real bee colonies in In the pioneering acklet of Yang and Deb, the CSA has been implemented successfully in optimizing several benchmark functions, and their findings showed that the global search ability of the CSA is more efficient than GA and PSO [ 78 ].

Start with a population of possible solutions, a new and potentially better solution cuckoo egg is generated. New articles related to this author’s research. Cuckoos, probably one of the most vicious and cunning species of all bird breeds, clandestinely lay their eggs in the nests of other host birds, sparing themselves the parental responsibilities of raising the young. An idea based on honey bee swarm for numerical optimization. Therefore, the control parameters of the basic ABC should be tuned according to given blt of optimization problems.

As shown in this figure, there is a long, narrow and parabolic shaped valley in the surface plot.
