Hi John,<br>
<br>
Thanks for the answer. I've tried already to use "primaRanging" but I
cannot understand how. Here a simple example:<br>
<br>
<tt>var X0;<br>
var X1;<br>
var X2;<br>
<br>
minimize res: +1*X2;<br>
subject to v0: +6.97051*X0+4.19324*X1>=66.1712;<br>
subject to v1: +1.12876*X0+7.95129*X1>=64.4972;<br>
subject to v2: +3.84837*X0+6.76584*X1-1*X2<=702.355;<br>
subject to v3: +6.7965*X0+2.0752*X1<=38.3934;<br>
subject to v4: +1<=X0<=+66.1712;<br>
subject to v5: +1<=X1<=+66.1712;<br>
</tt><br>
I've solved above model and after I've put this piece of code:<br>
<br>
<tt>solver->primalRanging(n,which,valueIncrease,sequenceIncrease,valueDecrease,sequenceDecrease);<br>
cout << "PRIMAL RANGE: ";<br>
for (i=0;i<n;i++)<br>
{<br>
cout << " X"<<i << " increase " <<
valueIncrease[i]<<":"<<sequenceIncrease[i]<<"
decrease
"<<valueDecrease[i]<<":"<<sequenceDecrease[i];<br>
}<br>
</tt><br>
and I've following output:<br>
<br>
<tt>PRIMAL RANGE: X0 increase 64.608:0 decrease 0.563167:0 X1 increase
52.9892:1 decrease 12.182:1 X2 increase 1.79769e+308:2 decrease
1.79769e+308:2<br>
<br>
</tt>With ampl I get (I'm instrested in v3 ranging):<br>
<br>
<tt>ampl: display v3.up,v3.current,v3.down;<br>
v3.up = 62.506<br>
v3.current = 38.3934<br>
v3.down = 36.0944<br>
</tt><br>
How I can "read" primalRanging result? <br>
<br>
Thanks,<br>
<br>
Daniele.<br>

<br>
Is there any way with CLP to have RHS constraints sensitivity analysis
? <br>
Something like v1.up,v1.current and v1.down (v1 constraint name) for <br>
ones familiar with AMPL and CPLEX?<br>
<br>
Thanks in advance,<br>
<br>
Daniele.<br>
