<p class=MsoNormal><font size=3 face="Times New Roman"><span style='font-size:
12.0pt'>Having build a model in flopc++ I now need to interpret the results of
the model. However, I find it hard to map variables back to domains.
Furthermore, I need to lookup in subsets according to a variables index in a
given domain. ( i.e. I have a subset DP(D,P) and I have the index for
D=idx - how do I get the P.such_that(DP(idx,P) returns me the indexes ?)<br>
<br>
I have tried looking at forall and such_that defined for sets, but cannot
really make it work. Is there a functionality in flopcpp that I am overlooking,
which enables me to map a solution vector back to the domains defining the
variable? <br>
<br>
I realise that I can simply iterate through the sets, but there is much
redundant work combined with this, when all i need is a reverse map from an
index(indices) to a domain.<br>
<br>
Another request is references to good examples on the web on how to interpret
the results of the LP back to the domains, that defined them. <br>
