About Gepsoft

Founded in 2000, we are the
creators of GeneXproTools.

 
 
 


History
 

Gepsoft Limited is a predictive modeling software company located in Bristol, United Kingdom. Gepsoft was founded in 2000 to market the Gene Expression Programming (GEP) technique invented by Dr. Candida Ferreira, founder and currently director of Gepsoft. The first product to be released was a COM component (GEPSR 1.0 and 2.0) followed by the desktop application APS (Automatic Problem Solver), which won the 2001 Microsoft Portugal Software Award (Science). Gepsoft continues to develop this product, which was renamed GeneXproTools (Gene Expression Programming Tools) after version 4.0.


The first version of APS, which only supported symbolic regression, was launched in February 2001. Later that year Gepsoft released a second improved version that also introduced the Classification algorithm. Version 3.0 was released in 2003 after a complete rewrite and introduction of new algorithms for Time Series Prediction and the GEP-RNC algorithm for integrating random numerical constants. Version 4.0 was released in July 2006 and supports for the first time unlimited datasets (for both variables and samples) and new algorithms for Logic Synthesis and model simplification.

Two months later, in September of 2006, Gepsoft released the software GeneXproServer 1.0, an add-on to GeneXproTools 4.0 and a powerful batch processor of GXPT runs that is essential for the unattended processing of many different datasets.



Research
 

Besides its main website (http://www.gepsoft.com/), Gepsoft maintains a dynamic research website that tracks the developments in Gene Expression Programming:

The GEP algorithm outperforms the old Genetic Programming technique by a factor of 100 - 60,000. This groundbreaking performance brings predictive modeling to the average personal computer. These advances are due to a novel structural organization that more closely mirrors the evolutionary mechanisms in nature, making the design process not only thoroughly enjoyable but also highly efficient.

     


"Gene Expression Programming, combined with GeneXproTools, allow us here at Mercator GeoSystems to explore new and exciting methods for spatially modeling the relationship between a company's outlets and their customers. The GeneXproTools software is simple to use, well-designed and very flexible. In particular the ability to load training data from a database, and the option to create models in the program language of our choice, really make this product stand out. Product support is excellent and very responsive - heartily recommended!"

"I have been using GeneXproTools against a variety of drug research related problems and have found the GUI to be readily-usable and well-attuned to the stages of predictive modelling (...much easier than the command line software I'm used to using!!)."
