From: deepakc on 4 Feb 2010 11:50 Check out this paper - http://dspace.mit.edu/bitstream/handle/1721.1/46859/arcflowformulati00clau.pdf?sequence=1 The above paper appears to be a joint collaboration between MIT and a French institute, published in 1987. What I find interesting about this paper is that the authors mention in the Conclusion on page 13, that they are uncertain about the complexity of their algorithm. They also mention that the bound on the number of steps of their algorithm is most probably exponential, however, they are not certain about this. They also mention that P=NP if the bound is polynomial. Will some knowledgable person please be able to comment about this paper. Thanks, -Deepak |
