[in Turkish] Genetik Algoritmalar (Kitap)

Genetik Algoritmalar başlıklı kitabım Türkmen Kitabevinde satışa sunulmuştur. Kitaba aşağıdaki linkten ulaşılabilir: http://www.turkmenkitabevi.com.tr/genetik-algoritmalar-mehmet-hakan-satman-k251291.html Kitabın önsözü aşağıdaki gibidir: İnsan ve yeryüzünde yaşayan diğer canlılar arasındaki en büyük fark muhtemelen doğayla kurdukları ilişkinin şeklidir. Bir balık suda yüzerken neredeyse su kadar doğal görünürken; kafası karışık insan, neyi nasıl yapacağını düşünme karmaşasında kendini medeniyetler kurarken buluverir. Balık kendiliğinden… Read More »

Getting byte values of double type numbers in R using mcga

The R package mcga implements some functions for the Machine-coded Genetic Algorithms. Since the package is implemented for a specific issue, its utility functions can be used for any other purpose. Suppose you need to extract byte values of a double typed value in R. The functions DoubleToBytes, BytesToDouble, DoubleVectorToBytes, and ByteVectorToDoubles can be used… Read More »

ARIMA forecasting as a genetic inheritance operator in floating-point genetic algorithms

Paper: Satman M.H., Akadal E., “ARIMA forecasting as a genetic inheritance operator in floating-point genetic algorithms”, Journal of Mathematical and Computational Science , vol.6, no.3, pp.360-376, 2016 Abstract: In this paper, a new operator is developed for the floating-point genetic algorithms (FPGAs). The operator records the family tree of chromosomes, searches a convenient time series… Read More »

Logo for RCaller

Although it is developed since 2010, our open source project RCaller has not a real logo yet. If you design logos and want to contribute to project, please send a pull request including your logo design to https://github.com/jbytecode/rcaller. We look forward to receive your logo stuff!!

Fast online detection of outliers using least-trimmed squares regression with non-dominated sorting based initial subsets

Paper: Fast online detection of outliers using least-trimmed squares regression with non-dominated sorting based initial subsets Abstract: In this paper, a new algorithm is devised for calculating the Least Trimmed of Squares (LTS) estimator. The algorithm consists of two steps. In the first step, the non-dominated sorting algorithm is applied on the design matrix of… Read More »

Hybridization of floating-point genetic algorithms using Hooke-Jeeves algorithm as an intelligent mutation operator

Paper: Hybridization of floating-point genetic algorithms using Hooke-Jeeves algorithm as an intelligent mutation operator Abstract: Hybridization of genetic algorithms increases the search capabilities by means of convergence rate and speed. In this paper, we suggest to use Hooke-Jeeves algorithm as a genetic operator which performs a local search using the best chromosome in a generation… Read More »
