Selection for kicks: a soccer game as a Darwinian evolution process
Laura Guzmán

Gustavo Daniel
Soccer is a popular sport in which two teams play to score goals. It can be considered as a system in which different decision makers interact and configure the match from those interactions. Besides of being a social system, it is a system that evolves and learns during the match due to the fact that it shows variation, selection and retention of the different passes. Variation is related to the different possibilities that a player has to pass the ball without being intercepted by the other team and is affected by the way in which the players stand throughout the field. The passes will be successful if they arrive to the player to whom they were directed and will be selected by the player who made the pass. These selected passes will be retained by the players because they will have preference for those passes that have been successful. Although this process selects the passes that best fit the environment of the game, there is also a possibility of innovating in the passes and produce a new learning cycle that leads to the evolution of the passes of a team. From the construction of a simulation model in Netlogo we intend to show how the interaction of the agents involved in a soccer match constitutes an evolutionary process in which the most successful passes prevail over those that do not allow an advantage over the other team.

Learning to Recycle
Sandra Méndez

Mariana Mora
Research has shown that in developing countries the public sanitation system is deficient because of inadequate planning, lack of resources to implement related projects, and because urban planning decisions are being made with economic priorities but without considering environmental and social variables. Concerning cultural elements, urban Solid Waste Management, SWM, systems are greatly influenced by attitudes and behavior of household; however, lack of sustained public education programs on waste prevention and reuse is one of the main failure variables. This project integrates Multi Agents Simulation and Evolutionary Theory in order to visualize learning processes in generators of solid waste about separation for recycling, involving also observatory agents (incentives) and impacts in quality of territory caused for either high or low level of source separation of waste as well. This computer-based tool named Learning to recycle could be useful for environmental education activities and its posterior improvements could be used for conceiving, planning, and designing SWM strategies.

Social Responsibility From an Evolutionary Perspective

The main objective of this work is to develop a model that describes the behavior of the social activities within the Department of Industrial Engineering in Universidad de los Andes, illustrated from evolutionary epistemology. For this purpose, an introduction of the impact on society and the formation of the student by join a social activity is made and of the conditions that must be present for these activities to endure over time. Subsequently, through the algorithm of variation, selection and retention, the dynamics of the system and the impact of the interaction between students and the environment are explained, to finally conclude and propose alternatives that encourage student participation in activities with social impact.

The model addresses the behavior of the buying environment of products of Industrias Cruz Company. The model has three types of agents, the buyers, the points of sale of cross and the external points of sale so called distributors, who are the competition of the company. The model represents the evolutionary behavior of the trade. The shops have a cycle of life: creation, sales development and disappearance (immediately after lack of popularity against competition). The aim is the generation of own shops that fight for the same market, generating a competition and in consequence a constant disputes for the clients. In the buyers behavior we take four important aspects as decision variables: price, quality, time of delivery, and support, in such a way that the clients could choose the variable that seems to them to be more significant. The observer is the one that modifiessignificant variables with the aim to see how to compete against other distributors. A person buys in a shop when someone offers him the demanded article according to the most important variables for the client. The model is analyzed from an evolutionary perspective considering the processes of variation, selection and retention tied to the clients and his relation with the shops.

Bars Competition in an Open Population

Bars in Bogota are in constant change, each month a new one appears and another disappears and people even say that most bars do not go past the six months after their inauguration. It's the ever-changing state of this business that raises the question of how do bars manage to stay in operation. It’s for this reason that the present study aims to analyze the evolution of bars as a social system: see how they retain their customers and how they vary their features to remain on the market. Thus the simulation simulates 8 different bars and an open population that can choose which bar to go partying depending on their preferences (e.g. safety, types of music, budget or ambiance). Selection pressures for agents rely on their personal preferences (variety) but also in the word of mouth, a phenomenon critical to the success of these types of businesses. The model analyzes bars competition dynamics in an open population from an evolutionary perspective where there is variation, selection, and retention, this allows the system to express and show the characteristics established by Darwinian evolutionary systems. Therefore, when competing in real systems, Bars´ strategy must change and innovate constantly to ensure their survival and retention, as both the population and the environment are constantly changing. In this sense, the model aims to show how does the preference for going out of each person change as the strategies, used by bars to attract and retain customers, vary (and the way bars select strategies), and how bars adapt to the new market conditions in order to survive.
