Abstract:

Function packet sets (function P-sets) are a pair of function sets composed of a function internal packet set(function internal P-set) and a function outer packet set(function outer P-set), which have dynamic and law characteristics. Based on this, the concepts of internal packet iteration law, outer packet iteration law, and packet iteration laws are proposed. Also, theorems about existence and attribute supplement-deleting of packet iteration laws are presented. By using packet iteration laws, packet law reasoning is defined, and the theorem about packet law reasoning and the discovery of packet iteration law is obtained. Finally, packet law reasoning is applied to the discovery of unknown law in the scopes of risk investment.

Key words:  function packet sets; packet iteration laws; packet law reasoning; law discovery
