....and Gambardella Ant Colony System 5 Pheromone placed on the edges plays the role of a distributed long term memory: This memory is not stored locally within the individual ants, but is distributed on the edges of the graph. This allows an indirect form of communication called stigmergy [23] [9]. The interested reader will find a full description of ant system, of its biological motivations, and computational results in [12] Although ant system was useful for discovering good or optimal solutions for small TSPs (up to 30 cities) the time required to find such results made it ....

....in a group of distributed agents appears to be quite feasable and goes surprisingly fast. Cultural processes such as the ones proposed here, provide an alternative to genetic explanations for the origin [7] or acquisition of language [1] Self organization is very common in other areas of biology [2] and it is therefore not surprising that it might play an important role in language formation. 8 Acknowledgement The research and writing of this paper has been financed by the Belgian Federal government FKFO project on emergent functionality (FKFO contract nr. G.0014.95) and the IUAP ....

....This paper applies another mechanism than genetic evolution for structure formation to the problem of language formation, namely self organisation. Self organisation occurs in complex dynamical systems which are coupled in a particular way. Standard examples are the formation of a termite nest [2] or a path in an ant society. This paper focuses on the formation of vocabularies, i.e. a set of couplings between words and meanings. A common vocabulary will be viewed as a selforganising phenomenon similar to a path in an ant society. Each agent is assumed to create his own vocabulary in a ....

....For a particular agent and a particular meaning, there are now three possibilities and consequent actions: 1. 1 [1] The agent had a word for this meaning. This association k will be changed based on the probability p k which depends on c k using the same sigmoid function as before. 2. 2 [2] The agent did not have a word for this meaning. In that case, the agent selects a word from the words taking part in the conversation and associates it with the meaning. If there are not enough words left, the agent may create a new word and then create a new association. 3. 3 [3] The agent did ....

....a complete view of the language and no agent can control the linguistic behavior of the whole group. Moreover no separate mechanism for language acquisition is necessary because the mechanisms that explain the origin of language also explain how it is acquired by new agents entering the community. [2] Language spontaneously becomes more complex based on the same mechanisms that give rise to complexity in biosystems in general. The development and evolution of language is primarily driven by the need to optimize communicative success and handle the very strong constraints which hold for ....

....of materials that keeps the system in a non equilibrium state. As long as the condition is present, the dissipative structure will be maintained. Some standard applications of self organization can be seen in morphogenetic processes, or the formation of a path in an ant society or a termite nest [2]. A language can be viewed as a dissipative structure similar to a path in an ant society. Each agent is assumed to create and continuously change his own language in a random fashion, resulting in a fluctuating linguistic community. Language must be shared in order to obtain the benefit of ....

....not guarantee coherence because different subgroups of agents (in the extreme case each agent) may create their own words and associations instead. Self organisation in the sense of the spontaneous formation of dissipative structures by the amplification and damping of random fluctuations [9] [5] is a well known mechanism for achieving coherence without central control. It is here applied as follows: Agents randomly couple words to meanings, and engage in communication. They record the success of a particular word meaning pair and preferably use that in future communications. This ....
