Figure 2From: Detection of clusters of a rare disease over a large territory: performance of cluster detection methodsIllustration of the genetic algorithm method - offspring resulting from the cross between two parent areas. (a)-(b) the two parent areas. (c) cross between the two parent areas with units in parent 'a' and parent 'b' coded positively and negatively, respectively, and the intersection coded 0 (in green). (d)-(f) three offspring created using the genetic algorithm procedure (see [7]).Back to article page
