<strong>Definition:</strong>
A <a href="minimalperfh.html" tppabs="http://hissa.nist.gov/dads/HTML/minimalperfh.html"><em>minimal perfect hashing</em></a> function for keys in S such that if k1, k2  in S and k1 &gt; k2, then f(k1) &gt; f(k2).
<P><em>Note:
For example, if the keys are stored in order in an <a href="array.html" tppabs="http://hissa.nist.gov/dads/HTML/array.html"><em>array</em></a>, the array offsets are an order preserving minimal perfect hash of the keys.</em>
