1/27/2024 0 Comments Gplab toolboxThankyou so much to Marc Schoenauer’s students Flavien Billard, Aurlien Boffy, andThomas De Soza for spotting some nasty artificial ant bugs, and to MatthewClifton for the fruitful exchange of ideas and for providing most of the artificialant simulation code. I would like to address a big thank you to Henrik Schumann-Olsen, Jens Thiele-mann and Oddvar Kloster at SINTEF () for the exten-sive additional code they have provided for the first version of GPLAB. All the toolbox files had their timestamp changed. The lists of modified and new functions of this new release are availablein Appendices A and B. As always, modularity has been a priority, and GPLAB can noweasily adopt new survival methods as well as new fitness adjustment functions.Some minor changes were also made to ensure minimal compatibility with Oc-tave. Anothertechnique is based on the adjustment of fitness according to size, which impliedkeeping track of both the adjusted fitness and the raw fitness (equal when thereis no adjustment), and using the adjusted values along the selection process.Īll this implied major changes, resulting in a large extension of the operationalstructure itself. Many of these techniques are new and rely on a dy-namically changing population size, acting along the survival process. Version 3 implements several additionaltechniques for bloat control. The changes are alwaysbiased towards my own work, but I also try to incorporate different things thatI have come to realize other users need. GPLAB is slowly growing and (hopefully) improving. 3 and 4 respectively.Chapter 5 shows the available offline graphical capabilities of GPLAB, andChapter 6 presents a summary of all toolbox functions, organized in functionalgroups. Details on theavailable parameters and state variables are found in Chaps. Ĭhapter 2 describes the operational structure of GPLAB. Both are freely available fordownload at. This manualis accompanied by a zip file containing all the functions that form the toolbox,released under the GNU General Public Licence. It was tested on different MATLAB versions and com-puter platforms, and it does not require any additional toolboxes. Versatile, general-ist and easily extendable, it can be used by all types of users, from the layman tothe advanced researcher. GPLAB is a genetic programming toolbox for MATLAB. Toolboxes are collections of optimized, application-specific functions, which extend the MATLAB environment and provide a solidfoundation on which to build. Furthermore, its ex-tensive and straightforward data visualization tools make it a very appealingprogramming environment. Its programming language is simple and easyto learn, yet fast and powerful in mathematical calculus. MATLAB is a widely used programming environment available for a largenumber of computer platforms. 576.5 Description of parameter and state variables. 566.2 Running the algorithm and testing result. 514.10 Resources and variable size populations. 504.9 Complexity and diversity statistics/history. 484.4 Operator probabilities and frequencies. 37ģ.15 Operator probabilities in runtime. 313.10 Measuring complexity and diversity. 303.9 Measuring fitness - raw and adjusted. 132.4.3 Integrating new plug and play functions in GPLAB. 132.4.2 Using new plug and play functions. 132.4.1 Building plug and play functions.
