Clustering problems are solved using various techniques such as SOM and K-Means. The generic problem involves multi-attribute sample points, with variable weights. We use Genetic Algorithms to build a scalable, generic & easy to use solution.
Refal.NET - Versatile, Compact yet Powfull Text Transformer and Compiler-Writing System. Based on Refal.NET Virtual Machine (+Refal.NET Compiler), this RAD-tool might be used for rapid prototyping, decreasing up to 10 times development efforts.
A tutorial, using NeHe's code as a base, to trace a ray, perform a shortest path algorithm, find points relative to the screen, and other things. This will eventually become a rpg tactics game with the use of OpenGL.
