\), and \(w_j\) is the
weight for feature \(j\) (defaults to 1 for all features; see
<code><a href="add_feature_weights.html">add_feature_weights()</a></code> to specify weights). Additionally,
\(B\) is the budget allocated for the solution, \(c_i\) is the
cost of planning unit \(i\), and \(s\) is a scaling factor used
to shrink the costs so that the problem will return a cheapest solution
when there are multiple solutions that represent the same amount of all
features within the budget.</p>
