“…Such definition implies that the agent's actions are self-motivated, i.e., the agent's actions come from its internal dynamics of subsistence, and always seek the selfconstitution of the agent's system. That is called "Constitutive Autonomy", an essential property of life that has the potential to explain the intrinsic teleology of living beings, which are genuinely autonomous systems (Nogueira et al 2016;Vernon et al 2015).…”

“…EMOTIONAL can be classified as an EDE algorithm and, although there are no externally defined objectives, we still cannot talk about Constitutive Autonomy in this work, and thus we are not strictly following the precise agency definition aforementioned, since the artificial agent, a virtual robot, is always fully constituted. Nevertheless, we can simulate similar pressure based on the concept of precariousness, which generates the conditions to emerge what is called "Behavioral Autonomy" (Froese et al 2007;Froese and Ziemke 2009;Nogueira et al 2016;Vernon et al 2015), i.e., the emergent behavior is what controls an "energetic" level that makes itself possible, in a dynamic that counteracts the simulated precariousness, otherwise it would lead to the impossibility of agent movement. We also approached that idea (Nogueira et al 2013a) in our previous work about a simulated reproduction method of virtual agents.…”

“…Evolutionary computation (EC) has been a topic of considerable active development, and a widely applied approach to evolve behaviors of autonomous agents. We can mention several recent studies in the fields of robotics and virtual agents (Lehman and Miikkulainen 2014;Haasdijk et al 2014;Trueba et al 2015;Silva et al 2016;Nogueira et al 2016). Among these works, it is noticeable an increasing interest in open-ended evolution (OEE), out of the need for agents capable of evolving behaviors beyond a single predefined objective, and in embodied evolution (EE), particularly in robotics, in order to establish online adaptation.…”

“…Another OEE approach is based on Environment-Driven Evolution (EDE), i.e., evolution is promoted only by environmental pressures (Nogueira et al 2016). In that case, there is no explicit description of fitness function, and the best-fit individuals flourish naturally, according to the dynamics of the whole system.…”

This paper presents an embodied open-ended environment driven evolutionary algorithm capable of evolving behaviors of autonomous agents without any explicit description of objectives, evaluation metrics or cooperative dynamics. The main novelty of our technique is obtaining intrinsically motivated autonomy of a virtual robot in continuous activity, by internalizing evolutionary dynamics in order to achieve adaptation of a neural controller, and with no need to frequently restart the agent's initial conditions as in traditional training methods. Our work is grounded on ideas from the enactive artificial intelligence field and the biological concept of enaction, from which it is argued that what makes a living being "intentional" is the ability to autonomously, adaptively rearrange their microstructure to suit some function in order to maintain its own constitution. We bring an alternative understanding of intrinsic motivation than that traditionally approached by intrinsic motivated reinforcement learning, and so we also make a brief discussion of the relationship between both paradigms and the autonomy of an agent. We show the autonomous development of foraging and navigation behaviors of a virtual robot.

“…Autonomous power generation systems play an important role in the field of electricity generation [1], [2] which could combine several alternative and conventional energy sources, and are called hybrid systems by integrating only renewable energy sources or non-renewable energy systems [3], which have been widely used to meet different levels of demand [4], [5]. In this way, important energy simulation works of renewable hybrid systems are found [6] from renewable energy sources [7] and non-renewable.…”

This paper presents the methodology and results of the simulation and optimization of renewables and non-renewables energy system for supply to a shopping center as an alternative to the electric grid consumption, so that to determinate the optimal system. The fundamentals equations used to estimate the operational costs are presented. The software used to simulate and optimize the purposed system is HOMER ProÂ®, this software can simulate energy systems with renewable fractions and optimize those components to obtain the best system to use. In addition, the renewable systems they have the lowest annual operation cost and total operation cost in the simulated case study, therefore those systems should be consider as the better option to take as an alternative to the electrical grid consumption, but the non-renewable systems could be a great solution if the problem lies in obtaining an emergency plant, capable of generating large amounts of energy in a short period of time. Finally, that the renewable electric generating devices are the better option to use as an alternative to the electric grid consumption but it is recommended the use of an emergency plant with the final purpose of supply large amounts of energy if the situation requires it and this emergency plants should be natural gas electric generating devices or diesel electric generating devices.
