Field Documentation

unsigned int edge_info_def::back_edge

True if the edge is a loopback edge in the natural loop.

sreal edge_info_def::back_edge_prob

In case edge is a loopback edge, the probability edge will be reached in case header is. Estimated number of iterations of the loop can be then computed as 1 / (1 - back_edge_prob).
