The Tutte Polynomial - is a `crossing' the same as a `bridge'?
The following paper uses the term `bridge' in their definition of the Tutte polynomial:
Bennett Thompson, David J. Pearce, Craig Anslow, and Gary Haggard. Visualizing the computation tree of the tutte polynomial. In Proceedings of the 4th ACM sympo- sium on Software visualization, SoftVis ’08, pages 211–212, New York, NY, USA, 2008. ACM. Available from: http://doi.acm.org/10.1145/1409720.1409760, doi:http: //doi.acm.org/10.1145/1409720.1409760.
However, the Wiki page and other papers use the term `crossing'.
Are these the same thing or am I confusing them? What do you think?
