<title>Reporting</title>
<para>Solver can produce various kinds of reports that can be very
useful in practise. Currently there are five types of reports
that Solver can create for LP problems being solved.</para>
<sect3>
<title>Answer report</title>
Answer report reports the optimal solution found. It will give
you the original values of the input variables with the optimal
values. In addition, it reports all the model constraints,
their final values, right hand side values, binding status, and
slack.

<sect3>
<title>Sensitivity report</title>
</sect3>
<sect3>
<title>Limits report</title>
Limits report reports the attchieved optimal value all the input
variables of the model with the optimal values and with upper
and lower bound for the optimal value in with the particular
variable could vary without changing the optimal solution.
If an optimal value for a variable x is 4, for example, and the
lower bound is 2.4 and upper bound 5.9, then x could take any
value between 2.4 and 5.9, and still all the same constraints
were binding as with the optimal value 4. In limits report, you
can also find the value of the target cell for both upper
and lower bound values for the variable. For example, if the
optimal value where x is 4 leads to a profit of $5,000, limits
report specifies that if x is set to 2.4 the profit drops to
$3,640.

<title>Performance report</title>
In a performance report you will have various statistical
information about the problem, required computing time for
solving the problem, and various other information.
</sect3>
<sect3>
<title>Program report</title>
In a program report you will have the optimization problem
defined for the solver in a mathematical form. The output is
nicely formatted especially if you have placed proper labels for
each variable and constraint in the model.
A program report can be very useful, for example, if you want to
check that you have defined the problem correctly for the tool.
It is easy to make a mistake or two if you have large programs
to be solved.
