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.
