Multiple task selection protocol in a distributed problem solving network,into subproblems which can already be solved by the nodes. The aim of a problem solving network is to assign the subproblems to nodes which attempt to solve those cooperatively. The notion of Communication Functions is introduced to specify the behavior of cooperative nodes in distributed problem-so

We first describe our data model for statistical applications, based upon a twofold structure : relation and Complex Statistical Table (CST). Then, we present RTL, that encompasses relational algebra with aggregate operator, transformation operators, in order to achieve conversion betw
