An alert generator

An alert generator comprising a processor and a memory storage device incorporating instructions which when uploaded into the processor device enable performance of: collecting information comprised of many different variables; defining constraints that govern the generation of a hierarchical network of clusters from the information; generating an optimised hierarchical network of clusters that meet the constraints by repeatedly generating and testing different hierarchical networks of clusters by repeatedly: generating, at a first hierarchical level in the hierarchical network of clusters, clusters and generating, at a next lowest level in the hierarchical network of clusters, a number of smaller clusters as sub-sets of a respective cluster ; repeatedly generating, at a next lowest level in the hierarchical network of clusters, a number of smaller clusters as sub-sets of a respective sub-cluster; if the defined constraints cannot be met, abandoning the hierarchal network of clusters as a viable hierarchy of optimised clusters; if the defined constraints are met, saving the hierarchal network of clusters as a viable hierarchy of optimised clusters; selecting from the saved viable hierarchies of optimised clusters a most appropriate hierarchical network of clusters; receiving further information by recording, through digital technology, a telephone number used to make contact and using the further information to update the selected hierarchical network of clusters; and assessing the selected hierarchical network of clusters to produce a warning or an alert.
