pvat uses C++ LEDA library of the data types and algorithms of combinatorial computing. Algorithmic Solutions Software Gmbh, the current owners and developers of LEDA are no-longer issuing a free Research version and I do not have spare 900 Euros to purchase the full LEDA license. The linux version of PVAT compiled under an old linux segfaults and thelast free Research version 4 is no-longer compiling under modern linux systems. So the only way to run pvat now is under Microsoft Windows. Download pvat.zip, unzip, put pvat.exe on your path and optionally associate the icon pvat.ico with it. Sorry, I do not know how to make a proper installer under windows, but if anyone wants to help, be welcome!
