AN EFFICIENT POLYNOMIAL-TIME ALGORITHM TO DECIDE LIVENESS AND BOUNDEDNESS OF FREE-CHOICE NETS

In [3] J. Esparza presented an interesting characterization of structurally live and structurally bounded Free-Choice Nets (LBFC-Nets). Exploiting this characterization in combination with new results and refined algorithms the authors formulate an O(\P\\T\\F\) algorithm deciding whether a Free-Choice Net is a LBFC-Net or not. Furthermore the algorithm contains a simple and efficient test to ensure that the initial marking of a LBFC-Net is live. This test is based on a simplified characterization of liveness for LBFC-Nets.
