If there is a better solution, then this is a bug.<br>
<br>
If not, then it may be Cbc being intelligent e.g. preprocessing or
objective must be a multiple of N etc.<br>

<div> In Cbc, I use the following code to provide an incumbent
solution to the solver:</div>
<div><br>
</div>
<div>model.setBestSolution(solution,number-of-columns,ObjValue);<br>
</div>
<div><br>
</div>
<div>However when I call cbc to solve the problem, it finds out
that </div>

</div>
<div><b>The LP relaxation is infeasible or too expensive </b> <br>
</div>
<div><br>
</div>
<div>and uses my solution instead. So it doesn't really do any
search and says</div>
<div><br>
</div>
<div><b>Solution of </b>ObjValue <b>already found by heuristic</b></div>
<div><br>
</div>
<div> which is my solution since I have disabled heuristics. Is
there anyway to disable this feature and force Cbc solve the
LP relaxation and use my solution for an upperbound limit?</div>
