Gepsoft Limited is a predictive modeling software company located in Portugal.
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 Function
Finding, 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.
GeneXproTools 4.0 was released
in July 2006 and
supports for the first
time unlimited datasets
(for both variables and
records) 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 GeneXproTools runs that is
essential for the
unattended processing of
many different datasets.
In March 2008 Gepsoft
releases GeneXproTools
4.0 R2 with a new
algorithm for Logistic
Regression. In
October 2011
GeneXproTools 4.3 was
released with ensemble
methods and model
deployment to Excel,
with the add-on
GeneXproServer 4.3
following in March 2012. And in May 2013 Gepsoft releases GeneXproTools 5.0 with full support
for categorical variables and missing values and a multifunctional Data Panel for
powerful data analyses & visualization.
