In multi-criteria sorting methods, it is often difficult for decision makers to precisely define their preferences. It is even harder to express them into parameters values. The idea of this work is to automatically find the parameters of a sorting model using classification examples. The sorting method we are working with is FlowSort, which is based on the PROMETHEE methodology. Starting with ...

Incorrect statistical analysis: association among low whole blood viscosity, haematocrit, haemoglobin and diabetic retinopathy in subjects with type 2 diabetes In the recently published study by Irace et al the authors describe selecting two groups of individuals, one with and one without type 2 diabetes, the latter matched to the former with respect to age and sex. Although not explicitly stat...

The ESO Infrared Detector High Speed Array Control and Processing Electronics, IRACE, is designed as a modular system which supports readout and data processing of arrays with four, and eventually more, output channels. In addition, the system can handle several separate arrays by routing the data to multiple processing chains. Detector front-end(s) are galvanically isolated from the data proce...

Abstract In this paper we propose a hybrid metaheuristic based on Particle Swarm Optimization, which tailor portfolio selection problem. To motivate and apply our metaheuristic, reformulate the problem as an unconstrained problem, by means of penalty functions in framework exact methods. Our is it adaptively updates parameters model during optimization process. addition, iteratively refines its...

In this article, we present a distributed robot 3D formation system optimally parameterised by hybrid evolutionary algorithm (EA) in order to improve its efficiency and robustness. To achieve that, first describe the novel algorithm3 (DFA3), proposed EA, two crossover operators be tested. The EA hyperparameterisation is performed using irace package evaluation of three case studies featuring th...

INTRODUCCIÓN: La limpieza y conformación del conducto radicular es una de las etapas másimportantes durante el tratamiento endodóntico, lo cual difícil lograr en conductos ovales, ya que laslimas no llegan a instrumentar toda la superficie conducto. El instrumento XP-endo Finisher (FKGDentaire, La-Chaux-de-Fonds, Suiza) lima níquel-titanio fabricada con aleación Max Wire,que le permite al expan...

The optimal methods for the synthesis of mechanisms in rehabilitation usually require solving constrained optimization problems. Metaheuristic algorithms are frequently used to solve these problems with inclusion Constraint-Handling Techniques (CHTs). Nevertheless, most CHTs mechanisms, such as penalty function and feasibility rules, generally prioritize search feasible regions over minimizatio...

Automatic configuration techniques are widely and successfully used to find good parameter settings for optimization algorithms. Configuration is costly, because it necessary evaluate many configurations on different instances. For decision problems, when the objective minimize running time of algorithm, configurators implement capping methods discard poor early. Such not directly applicable op...

Introduction. This experimental study is to compare radiographs based on the penetration depth of the irrigant following three final irrigation techniques. Material and Method. A sample of sixty teeth with single roots were prepared with stainless steel K files followed by mechanized Ni-Ti files iRace® under irrigation with 2.5% sodium hypochlorite. Radiopaque solution was utilized to measure t...
