Concurrent languages such as Perl 6 fully leverage the power of current multi-core and hyper-threaded computer architectures, and they include easy ways of automatically parallelizing code. However, to achieve more computational capability by using all threads and cores, algorithms need to be redesigned to be run in a concurrent environment;in particular, the use of a reactive, fully functional patterns need to turn the algorithm into a series of stateless steps, with simple functions that receive all the context and map it to the next stage. In this paper, we are going to analyze different versions of these stateless, reactive architectures applied to evolutionary algorithms, assessing how they interact with the characteristics of the evolutionary algorithm itself and show how they improve the scaling behavior and performance. We will use the Perl 6 language, which is a modern, concurrent language that was released recently and is still under very active development.

Cloud-native applications add a layer of abstraction to the underlying distributed computing system, defining a high-level, self-scaling and self-managed architecture of different microservices linked by a messaging bus. Creating new algorithms that tap these architectural patterns and at the same time employ distributed resources efficiently is a challenge we will be taking up in this paper. We introduce KafkEO, a cloud-native evolutionary algorithms framework that is prepared to work with different implementations of evolutionary algorithms and other population-based metaheuristics by using micro-populations and stateless services as the main building blocks;KafkEO is an attempt to map the traditional evolutionary algorithm to this new cloud-native format. As far as we know, this is the first architecture of this kind that has been published and tested, and is free software and vendor-independent, based on OpenWhisk and Kafka. This paper presents a proof of concept, examines its cost, and tests the impact on the algorithm of the design around cloud-native and asynchronous system by comparing it on the well known BBOB benchmarks with other pool-based architectures, with which it has a remarkable functional resemblance. KafkEO results are quite competitive with similar architectures.

We consider the quantum query model for computing Boolean functions. The definition of the function is known, but a black box contains the input X=(x(1), x(2), ..., x(n)). Black box can be accessed by querying xi values. The goal is to develop an algorithm, which would compute the function value for arbitrary input using as few queries to the black box as possible. We present two different quantum query algorithms for computing the basic Boolean function - logical AND of two bits. Both algorithms use only one query to determine the function value. Correct answer probability for the first algorithm is 80%, but for the second algorithm it is 90%. To compute this function with the same probability in the classical model, two queries are necessary. We analyze algorithms implementation differences and propose a way to extend the first algorithm to compute AND of two functions.

Creating a concurrent and stateless version of an evolutionary algorithm implies changes in its algorithmic model. From the performance point of view, the main challenge is to balance computation with communication, but from the evolutionary point of view another challenge is to keep diversity high so that the algorithm is not stuck in local minima In a concurrent setting, we will have to find the right balance so that improvements in both facets do not cancel out. In this paper we address such an issue, by exploring the space of parameters of a population based concurrent evolutionary algorithm that yields to find out the best combination for a particular problem.

This work presents an analysis of the performances for four different implementations used to compute laser speckle contrast on images. Laser speckle contrast is a widely used imaging technique for biomedical applications. These implementations were tested using synthetic laser speckle patterns with different resolutions, speckle sizes, and contrasts. From the applied methods, three implementations are already known in the literature. A new alternative is proposed herein, which relies on two-dimensional convolutions, in order to improve the image processing time without compromising the contrast assessment. The proposed implementation achieves a processing time two orders of magnitude lower than the analytical evaluation. The goal of this technical manuscript is to help the developers and researchers in computing laser speckle contrast images.

In this paper, we elaborate on what we did to implement our self-structuring data learning algorithm. To recap, we are working to develop a data learning algorithm that will eventually be capable of goal driven pattern learning and extrapolation of more complex patterns from less complex ones. At this point we have developed a conceptual framework for the algorithm, but have yet to discuss our actual implementation and the consideration and shortcuts we needed to take to create said implementation. We will elaborate on our initial setup of the algorithm and the scenarios we used to test our early stage algorithm. While we want this to be a general algorithm, it is necessary to start with a simple scenario or two to provide a viable development and testing environment. To that end, our discussion will be geared toward what we include in our initial implementation and why, as well as what concerns we may have. In the future, we expect to be able to apply our algorithm to a more general approach, but to do so within a reasonable time, we needed to pick a place to start.

A large proportion of publications in the field of evolutionary computation describe algorithm specialisation and experimentation. algorithms are variously described using text, tables, flowcharts, functions or pseudocode. However, ambiguity that can limit the efficiency of communication is common. Evolutionary System Definition Language (ESDL) is a conceptual model and language for describing evolutionary systems efficiently and with reduced ambiguity, including systems with multiple populations and adaptive parameters. ESDL may also be machine-interpreted, allowing algorithms to be tested without requiring a hand-coded implementation, as may already be done using the esec framework. The style is distinct from existing notations used within the field and is easily recognisable. This paper describes the case for ESDL, provides an overview of ESDL and examples of its use.

The following article makes a case study with an SAP ERP system, which integrates with an external Web Service using API access. algorithm implementation is demonstrated with all transactions used in SAP ERP. However, it should be noted that a limited version of SAP ERP S/4HANA version release 2.00.044. It was pointing to the capabilities test between the external system and the ERP system. During the experiment, the ABAP programming language and the built-in SAP ERP background job are used and configured as needed. The received data is stored in the SAP ERP data warehouse, modified to save the new data. The main result is to provide integration capabilities. Utility to use the Web Service and the ERP system’s integration technique to enable the capability’s regular use. The experiment shows that the SAP ERP system can be integrated from an external source and store data to improve future business processes and increase its business values. The approach allows for the development of future frameworks and the expansion of ERP systems between external systems. © 2021, The Author(s), under exclusive license to Springer Nature Switzerland AG.

In this work, we will study a calculation method of variation formula with Riesz fractional derivative. As far as we know, Riesz derivative is a non-local operator including 2n directions in n−dimension space, which the difficulties for computation of variation formula rightly bother us. In this paper, we will give an accurate method to cope with element of the stiffness matrix using polynomial basis function in the general domain meshed by unstructured triangle and the proof of diagonal dominance for Riesz fractional stiffness matrix. This method can be utilized to general fractional differential equation with Riesz derivative, which especially suitable for β close to 0.5 or 1. © 2021 The Author(s)

The paper presents algorithms of on-line methods of discrete parametric identification of pollutant concentrations in a tunnel tube and comparison of their properties. It describes the characteristics of an individual methods and a detailed evaluation in order to select the most suitable method for the identification of dynamical systems with a significant stochastic component and changing parameters. The aim of the paper is to propose discrete parametric identification methods for systems that have variable parameters. It is a choice of model structure and design of an algorithm that is able to monitor changes in system parameters. The article also describes ways to implement identification algorithms in PLC (Programmable Logic Controller) by programming the target device directly from the simulation environment MATLAB Simulink using the toolbox "B&R Automation Studio Target for Simulink". From a practical point of view, these algorithms serve to create an apparatus for optimizing the ventilation control in the tunnel and thus ensure the safe passage of vehicles through the tunnel.
