List with the notation used in Algorithm 1

Symbol	Definition
GA, GB	Kernel density coordinates of samples A and B
A, B	pairs of coordinates of samples A and B that will be used
	to estimate OVL
$G_x^A\left[i\right],G_y^A\left[i\right]$	index a pair of coordinates of GA,
	where $G_x^A\left[i\right]$ is the abscissa and
	$G_y^A\left[i\right]$ is the correspondent ordinate (same to GB and G)
♯(.)	total number of pairs of coordinates
G	ordered list of points resulting from the union of A and B
P	union of G with new pairs of coordinates,
	which correspond to jump points between densities
G[i]	indexes a pair of coordinates of G
xnew	new abscissa
ynew	new ordinate
F	final list of pairs of coordinates to estimate OVL
OVL	overlapping coefficient between two kernel densities

Symbols are listed in order of appearance in the Algorithm.
