no unique method has been so far specified for determining the number of neurons in hidden layers of multi-layer perceptron (mlp) neural networks used for prediction. the present research is intended to optimize the number of neurons using two meta-heuristic procedures namely genetic and hill climbing algorithms. the data used in the present research for prediction are consumption data of water...

|This paper is concerned with function optimization in binary search spaces. It focuses on how hill-climbers can work together and/or use their past trials in order to speed up the search. A hill-climber is viewed as a set of mutations. The challenge is twofold: one must determine how many bits should be mutated, and which bits should preferably be mutated, or in other words, which climbing dir...

Biometric recognition systems are vulnerable to numerous security threats. These include direct attacks to the sensor or indirect attacks, which represent the ones aimed towards internal system modules. In this work, indirect attacks against fingerprint verification systems are analyzed in order to better understand how harmful they can be. Software attacks via hill climbing algorithms are impl...

We formulate a phase-field, or diffuse-interface, model for the evolution of stepped surfaces under surface diffusion in the presence of distinct material parameters across nanoscale terraces. In the sharp-interface limit, our model reduces to a Burton-Cabrera-Frank (BCF)-type theory for the motion of noninteracting steps separating inhomogeneous terraces. This setting aims to capture features ...

This paper revisits the old question of whether wage growth di¤ers by education level. Do more educated workers invest more than less educated workers in …rm speci…c, sector speci…c or general human capital? Do they gain more from improved job match? The paper makes both a methodological and a substantive contribution by o¤ering an alternative strategy for separately identifying returns to gene...

background:   to assess the outcome of the remplissage arthroscopic surgical method in patients with anterior shoulder dislocation associated with hill-sachs lesion.     methods:   ten patients with anterior shoulder dislocations and hill-sachs lesions were entered into this study and were operated on by the remplissage arthroscopic surgical method. they were followed up 22 months after surgery...

Abyssal hills are potential proxy records of mid-ocean ridge faulting and volcanism, as well the spreading rates mantle properties that influence these processes. Satellite gravity-based global prediction abyssal hill root-mean-square (RMS) heights could provide such a proxy, but broadly influenced off-axis by pelagic sediment cover, which can lower their values preferentially filling lows. Her...

In this paper, we generalize the models used by MacKay [1] in his analysis of evolutionary strategies that are based on sexual, rather than asexual, reproduction methods. This analysis can contribute to the understanding of the relative power of genetic algorithms over search methods based upon stochastic hill-climbing, e.g. [2], [3].

Methyl jasmonate and Epi-brassinolide as plant growth regulators have significant biological effects on plant growth, including increased tolerance to salt stress in plants. In this study, the effects of salinity stress and its interaction with methyl jasmonate and Epi-brassinolide on chlorophyll concentration, rate of photosynthesis, transpiration, stomatal conductance and resistance and chlor...
