Hello, everyone. Now I am using Pettis-Hansen method as follows to reorder functions. http://www.cs.virginia.edu/kim/courses/cs771/papers/pettis90profile.pdf But I found that the algorithm has its patent as below. http://www.freepatentsonline.com/EP0459192.html So if I use this algorithm in my codes, it will infringe the HP patent. Does it mean that this algorithm can not be used in codes ? Is there any method to deal with this problem ?
