$d\; (has,\; B)\; =\; \backslash \; min\_\; \{I\; \backslash \; in\; has,\; J\; \backslash \; in\; B\}\; (d\_\; \{ij\})$ $d\; (has,\; B)\; =\; \backslash \; sup\_\; \{I\; \backslash \; in\; has,\; J\; \backslash \; in\; B\}\; (d\_\; \{ij\})$ $d\; (has,\; B)\; =\; \backslash \; frac\; \{1\}\; \{card\; (A)\; card\; (B)\}\; \backslash \; sum\_\; \{I\; \backslash \; in\; has,\; J\; \backslash \; in\; B\}\; \{d\_\; \{ij\}\}$

$D\; (has,\; B)\; =\; D\; (g\_A,\; g\_B)\; ~$ $d\; (has,\; B)\; =\; \backslash \; frac\; \{w\_A\; w\_B\}\; \{w\_A\; +\; w\_B\}\; D\; (g\_A,\; g\_B)$ $\backslash \; log\; (ratio)\; \backslash \; neq\; 0$
