In cooperation with M. Myślak, P. Szufel and M. Jakubczyk we have created SilverDecisions applications.

The software allows for creation and analysis of decision trees.

The application can be used in web browser at

The develpmnent page of the project is avaliable on BitBucket.

localsolver package

In cooperation with WLOG Solutions company I have prepared localsolver package for R language.

The package is available for download at The Comprehensive R Archve Network and allows for solwing of large-scale global optimization problems. It employs advanced algorithms from hybrid optimization engine LocalSolver.

Asynchronous Knowledge Gradient

Implementation in Java language of the Asynchronous Knowledge Gradient algorithm can be downloaded here.

Documentation of the algorithm is presented in paper:
