feature has a persistence target of 50%, then a
solution which
secures a 95% chance of persistence will accrue the same benefit as a
solution which secures a 50% chance of persistence). Furthermore, weights
can also be used to specify the relative importance of meeting targets
for specific features (see <code><a href="add_feature_weights.html">add_feature_weights()</a></code>).</p>
