For example, consider the optimization problem:
 
For example, consider the optimization problem:
 +
<pre> min y = x1^2 + x2^2
 +
s.t. -1 < x1 < 1
 +
    -2 < x2 < 3
 +
    x1+x2 > 1
 +
</pre>
   −
<math>\alpha min y</math>
+
In this case there are two independent variables, x1 and x2, and one function variable, y. The data file that you load in Rave should thus look like:
    +
<pre>
 +
x1    x2
 +
-1    -2
 +
1      3
 +
</pre>
    +
This is the bare-minimum allowable data set: it contains all the independent variables and two rows of data that span the allowable ranges of the independent variables.
    +
*'''Note:''' Rave currently '''always''' enforces upper and lower limits for all independent variables during optimization. You cannot yet run optimizers that do not have constraints of the form a < x < b for every independent variable, x. Future versions of Rave will allow completely unconstrained optimization, however even in these future cases you will still need to load a two-line data set to start.
