numbers like 1.0e20 into their models<br>
because they might cause alot of rounding errors.<br><br>

Hi Everyone, <br>
<br>
I am getting fractional solutions for binary declared variables when I am
using Cbc solver; while CPLEX is returns a message: the problem is
integer infeasible.<br>
<br>
mps is available at the following link<br>
<a href="http://uts.cc.utexas.edu/~jeetv/MIPproblem.mps">
http://uts.cc.utexas.edu/~jeetv/MIPproblem.mps</a> (too big to be posted
here...) and I am using minimum.cpp of Cbc example file to solve
the mps file I have. <br>
<br>
Any help will be greatly appreciated..<br>
<br>
regards,<br>
vishy<br><br>
