Key Terms from the Complexity and Modeling Program:
-Complex
vs.
-Complicated
Complex: individual behaviors and local interactions, goal-specific emergent structure, scale-dependent predictability and unpredictability, high level of throughput.
Complicated: is deliberate, has specific goal driven behavior, predictable behavior at all scales, system throughout manages within specifications.
Complexity:
-Leaderless: individual behaviors and local interactions not directed by central organization or control.
-Emergent: unexpected structure that comes from a system that does not have a direct connection to the system.
-Nonlinear: inputs and outputs are related but not in a linear fashion. Highly sensitive initial and ambient conditions.
-Self-organizing: organization comes from within the system and is nonhierarchical
Word Wall:
Chaos:
A phenomenon seen in dynamical systems, in which the system's future behavior is highly sensitive to the initial conditions of the system. See also butterfly effect.
Feedback:
is a process in which information about the past or the present influences the same phenomenon in the present or future. As part of a chain of cause-and-effect that forms a circuit or loop, the event is said to "feed back" into itself.
Hierarchy:
Abstractly, a hierarchy can be modelled mathematically as a rooted tree: the root of the tree forms the top level, and the children of a given vertex are at the same level, below their common parent.
Occam's Razor:
The one with the fewest assumptions should be selected==
Pheromone
is a secreted or excreted chemical factor that triggers a social response in members of the same species. Pheromones are chemicals capable of acting outside the body of the secreting individual to impact the behavior of the receiving individual.
