Any large system that has gained sentience but not sophonce as an emergent property

This term is usually used for systems that to not normally evolve sentience, such as ecosystems, economical systems and electronic databases. To qualify as a sensestem, the system as a whole must show sentience, not merely contain sentient beings. Most known sensestems have evolved spontaneously, either when a system has gained a certain complexity through growth or else by some form of natural selection. Some sensestems are created by high transapient entities.
Sensestems usually possess some sense of self-preservation, and instinctively fight threats to their existence.
Self Modifying Code - Text by M. Alan Kazlev Any program that causes changes in portions of the program itself. Self-modifying code selectively stores, deletes, and transforms information within itself (for example, replacing problems with simpler subproblems), and ultimately expresses intelligent adaptive behavior. All ai and most alife use self-modifying code of some form or another.
Self-Organization - Text by M. Alan Kazlev based on original by Gary William Flake A spontaneously formed higher-level pattern or structure that emergences through the interactions of lower-level objects or patterns, whether in virch or r/l. Self-organization would seem to be a fundamental principle behind complexity in the universe, and is taken into account when creating new templates or designer nanecologies. Order, life and intelligence all seem to emerge through a process of self-organization. See also Self-Organized Criticality.
Self-Organized Criticality - Text by M. Alan Kazlev base on original Gary William Flake A mathematical theory (information age and later) that describes how a self-organized system may arise. Although transapient powers and minds long since developed more sophisticated patterns of understanding the emergence of complexity, subminds and superbright sapients find simulations using these protocols a useful way to map and understand dynamic behavior that is neither stable nor unstable but at a region near a phase transition.
