Try using stand-alone cbc or one of the example drivers which
effectively use the stand-alone cbc.<br>
<br>
First just try mipstart xxxxx.sol - that is simple and should help.<br>
<br>
The hotStart code can be turned on by giving a solution using
priorityIn with solution and then forceSolution --- but I would
have to check exactly how it works (now).<br>

I have got a large MIP to solve for which I would like to
implement a hot start strategy.<br>
<br>
My understanding is that I should use the function
CbcModel::setHotstartSolution(const double *solution, const int
*priorities=NULL),<br>
where solution assumes the same ''order'' of variables as defined
for the model itself. I am not so sure to understand the meaning
of<br>
the pointer priorities though. The hotstart solution I intend to
give is an actual feasible solution to the MIP.<br>
<br>
Am I on the right track?<br>
<br>
Thanks in advance for the help<br>
