This paper investigates the perform.nce and the results of an evolutionary algorithm.（EA） specifically designed for evolving the decision engine of a program.（which, in this context, is called bot） that plays Planet Wars. This gam., which was chosen for the Google Artificial Intelligence Challenge in 2010, requires the bot to deal with m.ltiple target planets, while achieving a certain degree of adaptability in order to defeat different opponents in different scenarios. The decision engine of the bot is initially based on a set of rules that have been defined after an em.irical study, and a genetic algorithm.（GA） is used for tuning the set of constants, weights and probabilities that those rules include, and therefore, the general behaviour of the bot. Then, the bot is supplied with the evolved decision engine and the results obtained when com.eting with other bots （a bot offered by Google as a sparring partner, and a scripted bot with a pre-established behaviour） are thoroughly analysed. The evaluation of the candidate solutions is based on the result of non-determ.nistic battles （and environm.ntal interactions） against other bots, whose outcom. depends on random.draws as well as on the opponents＇ actions. Therefore, the proposed GA is dealing with a noisy fitness function. After analysing the effects of the noisy fitness, we conclude that tackling random.ess via repeated com.ats and reevaluations reduces this effect and m.kes the GA a highly valuable approach for solving this problem.

The glacial history of Pico de Orizaba indicates that during the Last Glacial m.xim.m.its icecap covered up to~3000 m.asl;due to the air tem.erature increasing,its m.in glacier has retreated to 5050 m.*** retraction of the glacier has left behind an intense clim.tic instability that causes a high frequency of freeze-thaw cycles of great intensity;the resulting geom.rphological processes are represented by the fragm.ntation of the bedrock that occupies the upper parts of the *** is a notable lack of studies regarding the fragm.ntation and erosion occurring in tropical high m.untains,and the associated geom.rphological risks;for this reason,as a first stage of future continuous research,this study analyzes the freezing and thawing cycles that occur above 4000 m.asl,through continuous m.nitoring of surface ground *** results allow us to identify and characterize four zones:glacial,paraglacial,periglacial and *** was found that the paraglacial zone presents an intense drop of tem.erature,of up to~9℃ in only sixty *** rock fatigue and intense freeze-thaw cycles that occur in this area are responsible for the high rate of rock disintegration and represent the m.in factor of the constant slope dynam.cs that occur at the *** activity decreases,both in frequency and intensity,according to the distance to the glacier,which is where the tem.erature presents a certain degree of stability,until reaching the proglacial zone,where cycles are alm.st non-existent,and therefore there is no gelifraction *** geom.rphological processes have resulted in significant alterations to the m.untain slopes,which can have severe consequences in term. of risk and water.

The results presented here show for the first tim. the experim.ntal dem.nstration of the fabrication of lossy m.de resonance(Lm.) devices based on perovskite coatings deposited on planar waveguides. Perovskite thin film. have been obtained by m.ans of the spin coating technique and their presence was confirm.d by ellipsom.try, scanning electron m.croscopy, and X-ray diffraction testing. The Lm.s can be generated in a wide wavelength range and the experim.ntal results agree with the theoretical sim.lations. Overall, this study highlights the potential of perovskite thin film. for the developm.nt of novel Lm.-based devices that can be used for environm.ntal m.nitoring, industrial sensing, and gas detection, am.ng other applications.
