QCA implements the Qualitative Comparative Analysis using a boolean 
minimization algorithm for data coded with presence/absence of the causal 
conditions that affects a phenomenon of interest.

This new release has an experimental function that obtains the same exact 
solutions as the main minimization function, using a shortcut instead of the 
classical complete and exhaustive algorithm. This new function is faster and 
uses significantly less memory (50 MB compared to 1.5 GB for large datasets).

It should appear soon on CRAN, feedback is welcome.
