GPdotNET with new chart control

Posted on by

Blog post about new upcoming features of GPdotNET has posted here, but there is more. By releasing the new version of Visual Studio 2010 as well as the new windows forms chart control, I decided to replace existing ZedChart with one in the Visual Studio 2010. I wrote about the chart control in this post, and you can see how new chart control can be bind to database. In GPdotNET chart control is the main components for algorithm simulation, and you can see different usage of the control.  The picture below show chart control in action:

The first chart on the picture presents fitness simulation by simulating the best fitness as well as average fitness in the population. Another chart (below first one) is simulation of  training data (experimental data) and currently the best found GP model. GPdotNET simulation is very data intensive so it is necessary to have a chart control which is very fast and stable, like one in VS 2010.

GPdotNET – Memory issue with point decimal symbol

Few days ago GPdotNET beta was released, and received some mails that the program is consuming a lot of memory and its stuck. I tried to reproduce this issue but unfortunately I didn’t success. Analyzing  my code I realized that the localization should be a problem, cause there are some texts which need to be converted in to floating number like probability of reproduction, crossover and mutation. After correction, the issue is gone and program functions normally.

Regarding localization and different decimal symbol format  I published SampleData with point decimal symbol, to allow users to get initial sample for testing.

Finlay, I found some time to convert GPdotNET on Visual Studio 2010 solution, and make beta release with .NET 4.0 Client Profile.  The new version is the same as previous, and you no longer need ParallelFX CTP for running GPdotNET.

For running GPdotNETv0.9 you need to install only:

Just go to http://gpdotnet.codeplex.com and download the new version.

P.S: The next version of GPdotNET is still in development processes so be patient.
