Improved cuckoo search based neural network learning algorithms for data classification
… a novel meta-heuristic search technique called cuckoo search (CS) has gained a great deal of attention from researchers due to its efficient convergence towards optimal solution. But Cuckoo search is prone to less optimal solution during exploration and exploitation process due to large step …

A functional link neural network with modified cuckoo search for prediction tasks
… of tunable weight trained with the Modified Cuckoo Search algorithm (MCS). The proposed approach was used to predict the daily temperatures, relative humidity and ozone data. Extensive simulation results have been compared with standard MLP trained with the BP, FLNN with BP and FLNN with CS. …

Scheduling and Resource Efficiency Balancing: Discrete Species Conserving Cuckoo Search for Scheduling in an Uncertain Execution Environment
… of a novel evolutionary computation method Cuckoo Search (CS) is proposed, which has been adapted for solving combinatorial optimisation problems and modified to obtain multiple solutions. To test the proposed methodology, two sets of experiments are carried out. First, the developed …

An improved negative selection algorithm based on the hybridization of cuckoo search and differential evolution for anomaly detection
… which entail the use of the hybridization of Cuckoo Search (CS) and Differential Evolution (DE) in optimizing the random detectors of the V-Detectors. The DE is integrated with CS at the population initialization by distributing the population linearly. This linear distribution gives the …

A modified weight optimisation for higher-order neural network in time series prediction
… understand a dataset. In line with this, the Cuckoo Search (CS) learning algorithm, a kind of metaheuristics techniques employs high-level techniques for exploration and exploitation of the search space in which its step length is much longer in the long run. Thus, can explicitly being used to …

Frontline interactions between avian interspecific brood parasites and their hosts
… of the primary hosts of the Horsfield's bronze-cuckoo, Chalcites basalis, as a model species to investigate frontline defences in hosts. I show that recognition of adult brood parasites by cuckoo naive superb fairy-wrens can be achieved by social learning (chapter 3), they vary their nest …

The mechanisms underlying convergent evolution in the plumage patterns of birds
… explanations may also result in convergence. Cuckoo-hawk mimicry has been demonstrated in the common cuckoo (Cuculus canorus) and the Eurasian sparrowhawk (Accipiter nisus), but may be prevalent in Old World cuckoos. Randomly selecting a parasitic cuckoo from each genera of Old World cuckoos …

Coevolutionary causes and consequences of high-fidelity mimicry by a specialist brood parasite
… rare example of a “perfect mimic” is the African cuckoo Cuculus gularis (a specialist parasite of fork-tailed drongos Dicrurus adsimilis) which, to the human eye, exhibits some of the most sophisticated mimicry seen in a brood parasite-host system. In this work, I quantify the degree of mimetic …

Exploiters and exploited: antagonism, mutualism and mimicry in an ecological community
… and their specialist parasite, the African cuckoo Cuculus gularis. The coevolutionary battle between these bird species plays out amid a species-rich ecological community in the miombo woodlands of sub-Saharan Africa. Together with a field team in Choma, Zambia, I conducted experiments …

OpenKV: LSM-tree-based key-value store for open-channel SSD
… designed a central lookup table based on the cuckoo filter to utilize the open-channel SSD's direct page-level access. In our evaluation we show that compared to LevelDB, our design can reduce write traffic by 2.6x to 3.5x while improving random read performance by up to 1.8x.
