+<ul>
+<li><b>Minimum diagonal</b> - will be used the edge with the smallest length.</li>
+<li><b>Aspect Ratio</b> - will be used the edge which splits a quadrangle
+in order to optimize an Aspect Ratio quality criterion. The reference value is 1.</li>
+<li><b>Minimum Angle</b> - will be used the edge which splits a quadrangle
+in order to optimize a Minimum Angle quality criterion. The reference value
+is 60 degrees.</li>
