Graph matching problem with bounded degree to Graph isomorphism of bounded degree problem then our original problem will have tractable solution. Appreciate any help or pointer which may take us close towards the solutions." Thanks in advance Khris. On Jul 4, 2012, at 8:25 PM, Petr Savicky [via

zer use to use LP relaxation first? Is there way to control in some way Branch and Bound algorithm used by lpSolve apart from the going in side the code and tweaking it. Appreciate your feedback. Thanks Khris. On Jul 4, 2012, at 8:25 PM, Petr Savicky [via R] wrote: > On Mon, Jul 02, 2012

complexity from n^4 to n^2 where n is the number of sensors. 2. Another alternative could be that opt problem may fall in the category of semi definite programming, then we have efficient solvers for that. This is the story, appreciate your feedback.
