Hi Natalia,<br>
<br>
have you checked the solution status of the LP by calling
SCIPgetLPSolstat(scip)? What does the method return?<br>
<br>
Cheers,<br>
Jakob <br>

<div>I am trying to multiply the result that I get from

<p class="gmail-p1">SCIP_Real x = SCIPgetDualsolLinear(scip,

<p class="gmail-p1"><span class="gmail-s1">by -1 and add it it
to an objective function. I understand that the best way
to do this would be to set a fixed variable to one and set
the value as the coefficient. But when everytime i
mulitply by -1, I get an absurdly large number that is not
the actual value. I am very confused as to why this is
happening, seems that it should be simple.</span></p>
