<p class=MsoNormal style='margin-bottom:12.0pt'>I think setRowPrice sets the
dual solution - not the (primal) row solution.<br>
<br>
Internally, it is the rowActivity_ array that needs to be set - that is what is
returned by getRowActivity(). That is why you are not seeing it come back - you
are actually setting the duals with setRowPrice.<br>
<br>
I am not sure what it does to internals, but I think all you need is a method
&quot;setRowSolution&quot; and do a memcpy into rowActivity_.<br>

&nbsp; &nbsp; &nbsp; &nbsp;Osi.setColSolution and Osi.setRowPrice will set the
column and row<br>
solution, respectively. &nbsp;Row activity should follow from setColSolution.<br>
<br>
&nbsp; &nbsp; &nbsp; &nbsp;Based on the Osi unit test, OsiClp ignores imposed
row and column<br>
solutions (at least, they are not immediately reflected in the results returned<br>
for row activity and reduced costs).<br>
