Lindenmayer Grammars have been applied frequently to represent fractal curves. In this work, the ideas behind Grammar Evolution are used to automatically generate and evolve Lindenmayer Grammars that represent fractal curves with a fractal dimension that approximates a pre-defined required value. For many dimensions, this is a non trivial task to be performed manually. The procedure we are prop...

Recent research has indicated that grammar design is an important consideration when using grammar-based Genetic Programming, particularly with respect to unintended biases that may arise through rule ordering or duplication. In this study we examine how the ordering of the elements during mapping can impact performance. Here we use to the standard GE depth-first mapper and compare the performa...

Designing generic problem solvers that perform well across a diverse set of problems is a challenging task. In this work, we propose a hyper-heuristic framework to automatically generate an effective and generic solution method by utilizing grammatical evolution. In the proposed framework, grammatical evolution is used as an online solver builder, which takes several heuristic components (e.g. ...

This paper deals with a new approach for solving fuzzy differential equations based on genetic programming. This method produces some trial solutions and seeks the best of them. If the solution cannot be expressed in a closed analytical form then our method produces an approximation with a controlled level of accuracy. Furthermore, the numerical results reveal the potential of the proposed appr...

Hemiplegia is a condition caused by brain injury and affects significant percentage of the population. The effect patients suffering from this varying degree weakness, spasticity, motor impairment to left or right side body. This paper proposes an automatic feature selection construction method based on grammatical evolution (GE) for radial basis function (RBF) networks that can classify hemipl...

Nowadays, recommender systems are vital in lessening the information overload by filtering out unnecessary information, thus increasing comfort and quality of life. Matrix factorization (MF) is a well-known system algorithm that offers good results but requires certain level knowledge some effort on part user before use. In this article, we proposed an improvement using grammatical evolution (G...
