In this paper we use analytic programming method for optimal control synthesis. We developed variation version of the analytic programming to improve the search process efficiency. The method perform search over the set of the small variations of the given basic solution. Search efficiency depends on the basic solution. We give an example of optimal control synthesis for the three-dimension system with the state constraints over the set of the initial states using this method. (c) 2021 The Authors.

This paper provides a closer insight into applicability and performance of the hybridization of symbolic regression open framework, which is analytical programming (AP) and Differential Evolution (DE) algorithm in the task of time series regression. AP can be considered as a robust open framework for symbolic regression thanks to its usability in any programming language with arbitrary driving metaheuristic. The motivation behind this research is to explore and investigate the applicability and differences in performance of AP driven by basic canonical entirely random or best solution driven mutation strategies of DE. An experiment with four case studies has been carried out here with the several time series consisting of GBP/USD exchange rate. The differences between regression/prediction models synthesized using AP as a direct consequence of different DE strategies performances are statistically compared and briefly discussed in conclusion section of this paper.

This research deals with a novel approach to classification - pseudo neural networks (PNN). This technique was inspired in classical artificial neural networks (ANN), where a relation between inputs and outputs is based on the mathematical transfer functions and optimised numerical weights. Compared to ANN, the whole structure in PNN, i.e. the relation between inputs and output(s), is fully synthesised by evolutionary symbolic regression tool - analytic programming. Compared to previous synthesised models, the PNN in this paper were synthesised via a new approach to constant estimation inside the analytic programming - direct coding. Iris data was used for the experiments and PNN were used for the synthesis of a complex classifier for more classes. For experimentation, Differential Evolution (de/rand/1/bin) for optimisation in analytic programming (AP) was used.

The paper deals with the discovery of trigonometric identities of four functions via analytic programming and four strategies of Differential evolution (canonical DE/Rand/1/Bin, chaos-based DE/Rand/1/Bin-Lozi, DE/Rand/1/Bin-Burgers and SHADE). The results showed that all four strategies were comparable for this specific task.

This research deals with different approaches for constant estimation in analytic programming (AP). AP is a tool for symbolic regression tasks which enables to synthesise an analytical solution based on the required behaviour of the system. Some tasks do not need any constant estimation - AP is used in its basic version without any constant estimation handling. Compared to this, cases like data approximation need constants (coefficients) which are essential for the process of precise solution synthesis. This paper offers another strategy to already known and used by the AP from the very beginning and approaches published recently in 2016. This paper compares these procedures and the discussion also includes nonlinear fitting and metaevolutionary approach. As the main evolutionary algorithm, a differential algorithm (de/rand/1/bin) for the main process of AP is used.

In the known methods of symbolical regression by search of the solution with the help of a genetic algorithm, there is a problem of crossover. Genetic programming performs a crossover only in certain points. Grammatical evolution often corrects a code after a crossover. Other methods of symbolical regression use excess elements in a code for elimination of this shortcoming. The work presents a new method of symbolic regression on base of binary computing trees. The method has no problems with a crossover. Method use a coding in the form of a set of integer numbers like analytic programming The work describes the new method and some examples of codding for mathematical expressions.

This research deals with the hybridization of symbolic regression open framework, which is analytical programming (AP) and Differential Evolution (DE) algorithm in the task of time series regression. This paper provides a closer insight into performance comparisons of connection between AP and different strategies of DE. AP can be considered as a powerful open framework for symbolic regression thanks to its applicability in any programming language with arbitrary driving evolutionary/swarm based algorithm. Thus, the motivation behind this research is to explore and investigate the differences in performance of AP driven by basic canonical strategies of DE as well as by the state of the art strategies, which is Success-History based Adaptive Differential Evolution (SHADE) and its variant L SHADE. Simple experiments have been carried out here with the four different time series of EUR/USD exchange rate. DE performance analysis, as well as the differences between regression models synthesized using AP as direct consequences of different DE strategies performances, are both discussed within conclusion section.

The differences between regression/prediction models synthesized by means of AP as a direct consequences of different DE strategies performances are briefly discussed within conclusion section of this paper.
