	Emergent Game Technologies: Emergent's Behaviour
		Gamebryo vendor Emergent is riding a wave of expansion and announcements, recently unveiling a new online games platform and increased support for Wii in its game engine.
		Emergent Platform is built to encourage all of that.
		And support isn't just a matter of supporting your customers, its about testing and how you develop and how you document and how you comment your code and THEN how you support your customer, and NDL did that better than anyone in the industry and that's one of the primary reasons why we acquired them.

	Emergence - Wikipedia, the free encyclopedia
		One reason why emergent behaviour occurs is that the number of interactions between components of a system increases combinatorially with the number of components, thus potentially allowing for many new and subtle types of behaviour to emerge.
		Emergent structures are a favorite strategy found in many animal groups: colonies of ants, piles of termites, swarms of bees, flocks of birds, herds of mammals, shoals/schools of fish, and packs of wolves.
		Emergent processes or behaviours can be seen in many places, from any multicellular biological organism to traffic patterns, cities or organizational phenomena in computer simulations and cellular automata.

	Emergent Properties
		The existence of emergent qualities thus described is something to be noted, as some would say, under the compulsion of brute empirical fact, or, as I should prefer to say in less harsh terms, to be accepted with the “natural piety” of the investigator.
		Predictive: Emergent properties are systemic features of complex systems which could not be predicted (practically speaking; or for any finite knower; or for even an ideal knower) from the standpoint of a pre-emergent stage, despite a thorough knowledge of the features of, and laws governing, their parts.
		Do emergent features necessarily appear in all systems attaining a requisite level of complexity, or is this at best a contingent fact?) Nor does he indicate a position on the nature of causation itself, an issue that is crucial to understanding what the nonsupervenience of causal powers amounts to.

	Emergence and Self-organisation
		Emergent phenomena are observable at a macro-level, even though they are generated by micro-level elements.
		Emergent phenomena occur due to the pattern of interactions (non-linear and distributed) between the elements of the system over time.
		Behaviour which takes into account such emergent features might be called second-order emergence’ (as opposed to first-order emergent behaviour).

	AAAI Symp 99 Narrative (Site not responding. Last check: 2007-10-20)
		Emergent narrative may seem paradoxical since the underlying structure provided by a definite plot (or equivalent - a plot in the classic sense may not be the only type of high-level narrative structure) seems needed to make a narrative ‘hang together’.
		An emergent narrative is essentially supplying the raw material for a ‘storification’ process which is subjective and related to individuals [Dautenhahn 99] so that from a more global perspective there may be a number of different narratives depending on whose storifaction process we consider.
		Thus character-driven emergent narrative is not the only way of tackling the issue — in simple cases event-driven narrative can be produced assuming that the agents have a suitable repertoire of behaviours.

		Other postings imply that the term "emergent properties" is tautologous, and not unique to biology; it has been claimed that everything has emergent properties, so the adjective "emergent" is meaningless.
		Three systems with emergent properties that have been well examined are (a) artificial neural networks, (b) organisms that exhibit schooling or flocking behaviour, and (c) cellular automata.
		It is this bottom-up, distributed, local determination of behaviour that AL employs in its primary methodological approach to the generation of lifelike behaviors.

		These behaviour patterns are in turn driven by simple virtual sensors while groups of behaviour patterns (packets) are activated or deactivated according to the level of the Teletubbies’ internal drives, such as hunger, fatigue and curiosity.
		This physical behaviour can be thought of a s more cognitively determined by the character: exactly what words to say, for example; or more reactively determined: as in stumbling or laughing involuntarily.
		Emergent narrative may seem paradoxical since the underlying structure provided by a definite plot (or equivalent - a plot in the classic sense may not be the only type of high-level narrative structure) seems needed to make a narrative ‘hang togeth er’.

	EMERGENCE FACTS AND INFORMATION
		This can be a dynamic process (occurring over time), such as the evolution of the human brain over thousands of successive generations; or emergence can happen over disparate size scales, such as the interactions between a macroscopic number of neurons producing a human_brain capable of thought (even though the constituent neurons are not themselves conscious).
		Emergent processes or behaviours can be seen in many places, from any multicellular biological organism to traffic patterns, cities or organizational phenomena in computer_simulations and cellular_automata.
		position, momentum, and so forth, is actually an emergent phenomenon, with the true state of matter being described instead by a wavefunction which need not have a single position or momentum.

	[No title]
		The flocking behaviour of birds can be considered an emergent behaviour, since there is no external intelligence planning it and no global communication from a lead bird.
		Self-organizing behaviour normally denotes organized structures and patterns which arise from random initial conditions in systems, usually with large state spaces, which converges to a relatively small subset (called the attractor basin) of the state space.
		Emergent behaviour such as trail-building, to and from food sources, require groups of ants to reach a critical threshold of interest which is communicated via scents.

		What distinguishes a complex system from a merely complicated one is that in a complex system, some behaviours and patterns emerge as a result of the patterns of relationship between the elements.
		Many speculate that consciousness and life itself are emergent properties of a network of many interacting neurons and living cells, respectively.
		In physics, emergence is used to describe a phenomenon which occurs at macroscopic scales but not at microscopic scales, despite the fact that a macroscopic system can be viewed as a very large ensemble of microscopic systems.

	the "emergent" in "emergent church"
		When teaching emergent behaviours and chaos theory here at London School of Theology, I use that example and also the flock of birds in flight.
		Emergent systems rely on the individual members conforming to their roles and to the rules that govern them rather than doing any thinking or processing of larger goals themselves.
		It's difficult to imagine a description further from the truth in the emergent church conversation where everyone's thinking hard, everyone's thinking outside everyone else's boxes and everyone has at least one eye on the larger picture.

	Playtesting - Peter Bayliss: Research Archives (Site not responding. Last check: 2007-10-20)
		Jesse Rothenberg has recently posted on Ludonauts, arguing that emergent behaviour is a separate phenomenon to what he calls design artefacts.
		While the later type of emergent behaviour may well be described as a design artefact this view falls apart under closer scrutiny.
		And apparently the mine-climbing behaviour in Half-Life is enough of a surprise that the game’s designers didn’t consider it, as it seems unlikely they would create an objective, only to provide a simple way for the player to side-step their hard work.

	The Global Dynamics of Cellular Automata
		Such emergent behavior in complex systems, relying on distributed rather than centralized control, has become the accepted paradigm in the attempt to understand biology in terms of physics (and vice versa?), encompassing such great enigmas as the phenomena of life and the functioning of the brain.
		Such emergent behaviour has lead to the notion of computation emerging spontaneously close to what may be a phase transition in CA rule space.
		Emergent behaviour in 2-D CA has given rise to the new field of artificial life.

	ARTIFICIAL CREATIVITY
		The parameters that control the behaviour of individuals can be experimented with to study the affect that they have on the emergence of social structures.
		Temperature and pressure are emergent properties of large ensembles of molecules and are due to interactions at the molecular level.
		Importantly, the personal creativity tests play a critical role in determining the behaviour of all of the different types of individuals and the socio-cultural creativity test is still and emergent property of the whole society.

	On Emergence and Explanation
		In spite of the existence in mathematics of a large set of yet undecided statements or conjectures about mathematical properties that may exemplify either deductible or observational emergence, it is a general observation that the most transparent and clear-cut cases of the two kinds of emergence are found within the logical and mathematical domain.
		The basic idea is, that an emergent property might be one that supervenes on, without necessarily being definable in terms of (or reducible to) a physical base, even though physical facts somehow fix or determine biological and psychological facts.
		Thus, observationally emergent meaning constitutes a problem for the semantic analysis in the Tarski tradition (which is set theoretical, truth functional and compositional), as well as for classical AI that follows `the formalist motto' of deducing semantics from syntax (cf.

	Exploring Agent Behaviour through Architectural Transformations
		The idea is to identify tendencies, especially emergent tendencies, by automating the search through possible parameterisations of the model and the choices made by the agents.
		However understanding the behaviour of interacting groups of autonomous agents by formal design methods has its limitations, and even the most carefully designed MAS can exhibit emergent behaviour unforeseen by its designers.
		It does not magically solve the problems in understanding all emergent MAS behaviour but is a useful addition to our menu of tools because it embodies a different trade-off between semantic richness and computational efficiency.

	Emergent Behavior
		Basically, all behaviour comes from individuals (where else would it come from?), but as someone else mentioned, the interactions are what makes things difficult to understand.
		Isn't it that emergent behaviour, well, emerges, form the interactions between the members of an ensemble, rather than from the behaviours of the members of the ensemble taken in isolation.
		The behaviour need not necessarily be a surprise to the designer, but it is very, very difficult to predict a priori what behaviour will emerge from a set of interactions.

	Manuel DeLanda, Virtual Environments as Intuition Synthesisers (1992)
		And beyond this, if emergent properties are as pervasive in nature as they seem to be, not only is one idea eliminated (that of reductionism).
		What this formulation overlooks is that the nonlinear dynamics underlying such emergent behaviours are a common property of both living and nonliving matter-energy, as the case of metallic alloys illustrates.
		Similarly, the exact same 'abstract mechanism' behind emergent properties in turbulent flows of water also underlie the coherent behaviour of photons in a laser beam, or the behaviour of countries at the outbreak of war.

		This behaviour, combined with alignment, results in the group seemingly moving as a single unit.
		This behaviour is achieved simply be giving the individuals the ability to adjust its heading to avoid obstacles in the environment.
		Once we have achieved realistic behaviour with a small number of fish of one species we will progressively add more individuals and more species all the while working to keep our ‘virtual fish’ behaving in a realistic manner.

	as days pass by, by Stuart Langridge » Blog Archive » Emergent behaviour in the blogsphere
		I’ve been thinking a little about the idea of emergent behaviour in the blogsphere, especially given recent comments concerning the spread of memes and so forth (Burningbird, Baldur).
		Emergent behaviour is defined by the Wikip�a as a complex behaviour which is shown by a collective of simpler agents, where that complex behaviour isn’t defined or coded into any one of the agents, and it can’t be easily deduced from an agent.
		It’s possible to assert, with some degree of believability, that the propagation of memes is an emergent behaviour from a collective of people; as Baldur notes, it doesn’t just occur among webloggers but in academe as well.

	Emergent Intelligence - GameDev.Net Discussion Forums
		This is absolutely NOT the definition of emergent behaviour or cooperative agents as used widely in the AI community and with reference to those definitions, the above carries several errors.
		For the time being, all I will say is that emergent behaviour is (typically) the result of nonlinear feedback mechanisms within sub-units of an entity that aren't specifically encoded to produce these 'emergent' outputs...
		Im not looking for flocking behaviour, im looking for cooperative problem solving behaviour, even if that problem solving "emerges" from the "hive", an example would be how ants solve the "find the path between A & B that takes the less energy to make"...

		Though emergence is important, its mechanism is either not well understood or it is limited to the domain of shapes.
		This deficiency can be compensated by considering definitions of emergent behaviour from the Artificial Life (ALife) research community.
		With these new insights, it is proposed that a computational technique, called evolving representations of design genes, can be extended to emergent behaviour.

		In a system where each agent is connected to and interacting with all other agents, the behaviour of the system is chaotic and random.
		This behaviour is known as emergent behaviour or the emergent property of the system.
		A number of artificial cellular automata have been devised to demonstrate emergent, complex behaviour in networks of simple agents.

		An emergent behaviour is shown when a number of simple entities (agents) operate in an environment, forming more complex behaviours as a collective.
		The complex behaviour is not a property of any single such entity, nor can it easily be predicted or deduced from behaviour in the lower-level entities.
		Emergent processes or behaviours can be seen in a lot of places, from any multicellular biological organism to traffic patterns or organizational phenomena to computer simulations.
