PPT-Matching Logic

A New Program Verification Approach Grigore Rosu and Andrei Stefanescu University of Illinois at UrbanaChampaign Question could it be that after 40 years of program verification we still lack the right semantically grounded program verification foundation.

Each case/control pair then has identical values on the matching factors. Requi Logic. Grigore. . Rosu. and Andrei Stefanescu. University of Illinois, USA. Main Goal.
