EWF 1.3

New release of EWF software, fixing some issues identified in the small time bridge sampler present in version 1.2

EWF 1.2

Some issues were identified with the small time bridge sampler, this has now been fixed through a new sampling function. We've also lowered the approximation thresholds for the diffusion approximation to 0.08 (down from 0.1) and for the bridge approximation to 0.025 (down from 0.04).

EWF version 1.1

We have patched up some bugs in the previous version, overhauled the user interface, simplified installation and included python bindings such that EWF can now be called from within python. We strongly encourage using EWF from within a python environment, and provide four ready-made functions which allow for the simulation of samples from both the diffusion and bridge diffusion, as well as the pointwise evaluation of the transition density for the neutral case. Users can further expose any C++ functionality present in EWF to python through the file EWF pybind.cpp.

Using EWF from command line as in the initial release has been deprecated and is no longer possible.

Initial Release

This is the initial release of EWF. The program is ready for use and allows for simulation from the laws of both Wright-Fisher diffusion and Wright-Fisher diffusion bridges whlist accounting for

• presence/absence of mutation
• any polynomial selection (including genic and diploid)
• any kind of boundary behaviour (absorbing, entrance or reflecting)

Please check the readme and config files for further details.
