OpenSnesim algorithm added!

OpenSnesim is a Open and Free python-based SNESIM (Single Normal Equation SIMulation) algorithm. It is released under BSD license.
Because of Python performance issues, this implementation is considered as proof-of-concept for research, testing and development.
It is recommended to run only 2D models using OpenSnesim. You can use it for 3D space and even for multifacial simulation, but it will costs much time and RAM to complete the simulation.... read more

HPGL 0.9.9 released!

Now HPGL use CLAPACK solvers instead of internal ones, which means
great performance boost on large scale linear equation solving problems.

HPGL 0.9.6 released!

- Added sub module geo.routines
- Module geo refactored (many changes in algorithms interfaces)
- SGS LVM: algorithm changed, now LVM-means preserved correctly
- IK/SIS: Median-algorithms now used by default for 2 indicators properties
- SGS: bug fixed for cdf_data case
- Random path bug fixed (was wrong for small grids with 100 or less cells)
- Project compilation scheme changed
- Packages for Python 2.5 & 2.6 (Windows + Linux) now builds
- FORTRAN order in arrays now optional (arrays will be converted to
FORTRAN order automatically inside algorithms).
- New GSLIB files read/write and VPC calculation functions – very fast now.
