Harrington and Derringer-Suich type desirability functions

soobench

cran
17th

Percentile

Collection of different single objective test functions useful for benchmarks and algorithm development.

90th

Percentile

Provides infrastructure to accurately measure and compare the execution time of R expressions.

signal

cran
82th

Percentile

A set of signal processing functions originally written for 'Matlab' and 'Octave'. Includes filter generation utilities, filtering functions, resampling routines, and visualization of filter models. It also includes interpolation functions.

fftw

cran
64th

Percentile

Provides a simple and efficient wrapper around the fastest Fourier transform in the west (FFTW) <http://www.fftw.org/> library.

19th

Percentile

Extends the BatchJobs package to run statistical experiments on batch computing clusters. For further details see the project web page.

ecr

cran
18th

Percentile

Framework for building evolutionary algorithms for both single- and multi-objective continuous or discrete optimization problems. A set of predefined evolutionary building blocks and operators is included. Moreover, the user can easily set up custom objective functions, operators, building blocks and representations sticking to few conventions. The package allows both a black-box approach for standard tasks (plug-and-play style) and a much more flexible white-box approach where the evolutionary cycle is written by hand.

tspmeta

cran
18th

Percentile

Instance feature calculation and evolutionary instance generation for the traveling salesman problem. Also contains code to "morph" two TSP instances into each other. And the possibility to conveniently run a couple of solvers on TSP instances.

twiddler

cran
17th

Percentile

Twiddler is an interactive tool that automatically creates a Tcl/Tk GUI for manipulating variables in any R expression. See the documentation of the function twiddle to get started.

rgp

cran
15th

Percentile

RGP is a simple modular Genetic Programming (GP) system build in pure R. In addition to general GP tasks, the system supports Symbolic Regression by GP through the familiar R model formula interface. GP individuals are represented as R expressions, an (optional) type system enables domain-specific function sets containing functions of diverse domain- and range types. A basic set of genetic operators for variation (mutation and crossover) and selection is provided.
