<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>In general, why is it that get/set col solution is necessary for
a good warmstart for primal simplex, but whenever <b>dual simplex</b> is used,
isnt it necessary to, for example, get/set<b> row prices</b> when warm

primal, etc) <o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>OsiClp has "lastAlgorithm_" but that’s private. <o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>On the other hand, ClpSimplex has the public "algorithm()"
but using osiClpModel->GetModelPtr()->algorithm() only works in resolve,
not in initialSolve, because initialSolve uses a separate solver and
borrowModel, so after an initialSolve, the osiClpModel->GetModelPtr()->algorithm()
is still 0 (!). At least, if I understand the code correctly..<o:p></o:p></span></p>

<br>
<span style='font-size:10.0pt;font-family:"Arial","sans-serif"'>I think the
trouble is that OsiClp trusts the current solution as well as the basis.
In Primal it will use the current solution and basis, which will explain
the behavior in Primal. In Dual, I am not sure what the problem is.
Presolve may make a small difference, but should not make a major
difference. Clp itself has more flexibility.</span> <br>
