Bluetooth is an industrial specification for wireless Personal Area Networks (WPANs) that allows the transmission of voice and data between devices via a secure radio link and free globally (2.4 GHz). The main objectives to be achieved with this standard are: Facilitate communications between mobile and fixed. Remove cables and connectors between them. Offer the possibility of setting up small wireless networks and provide data synchronization between our personal computers. Devices with greater intensity using this technology are those of the telecommunications and information technology staff, such as PDAs, mobile phones, laptops, personal computers, printers and digital cameras.

EVALUATION OF THE ALGORITHM



Let us assume that at a certain moment of their departure can choose between two moves: T1D or C5CR. Which play? You fit comfortably in his chair and quietly begin their analysis, saying to themselves the possible moves: I can play T1D and probably play A2CD, or take my DWP, which is now defenseless. What then? I like that position? But there are a move in his analysis and then put them face long, the play of the Tower and were not interested. Therefore, considering the horse-play. What if I C5CR? He can miss with P3TR I C4R game, capture the rioja with your Bishop, I again attacked and captured my Lady with their tower. That does not seem very accurate ... So the game of horse is not good. Must see again the hand of the Tower. If the game A2CD, I can answer P3AR, but if that happens to catch my DWP? I can play then? No, the play of the Tower is not good. I consider the play horse again. Therefore, C5CR, P3TR; C4R, A x C D x A, T5D's not good! So I should not move the horse. Try to move the tower again. T1D, D x PT. At this point, you throw a glance at the clock. Dios mio! And take thirty minutes wondering whether to move the tower or the horse. If true, you are really hard time. And then, suddenly, it happens the happy idea. Move that Torre or the horse? Unlike A1CD? And without any difficulty, without any analysis, you move the pin. Exactly as before, only without considering it. The previous story taken from the book Think like a great teacher, Alexander Kotov is a reflection of a situation fairly common even among players of great skill and high competitive level. We tend to devote 100% of our time and effort to the study of the theory leaving aside a critical element as is the ability to perform our calculations or assessments in an efficient manner. In-depth knowledge of patterns of any opening, we are safe and could lead to any material or positional advantage to the stage in the middle game and once at that point, our tactical training and strategic skills are not always sufficient to maintain or increase that advantage when our thinking is confused and unsystematic. It is in situations like the above, which weighed the adoption of a mechanism as algorithm analysis sistematizacion positions could bring big benefits. A flowchart is a graphical representation of the algorithm and an algorithm is a sequence of instructions that allow the resolution of a problem in the most efficient and simple as possible. Objectives achieved through the use of the algorithm: 1 .- It forces begin the analysis by the hand of the opponent (very important). 2 .- Allows to manage time more efficiently. 3 .- It reduces the loss of material through carelessness. 4 .- It requires analysis in the same way and in the same order, with no improvisation; convirtindose soon in a good habit. Note: The algorithm illustrated above is only an example that we need to try to convey the central idea, please use the forum or send us your ideas of what should be the final evaluation of algorithm variants on chess.

global algorithm An algorithm is an organized series of steps that describes the process to be followed for solving a specific problem. In 1970, together with John Henry Holland, was one of the most promising lines of artificial intelligence, the genetic algorithms. They are called so because they are inspired by biological evolution and its genetic and molecular basis. These algorithms do evolve a population of individuals subjected to random actions similar to those involved in biological evolution (mutation and genetic recombination), as well as a selection according to some criteria, depending on which determines the individual more adapted to survive, and which are less suitable, they are discarded. It is also known as evolutionary algorithms, and includes the strategies of evolution, evolutionary programming and genetic programming. Within the latter had made the curious: In 1999, for the first time in history, was granted a patent for an invention not made directly by a human being: an antenna in odd ways, but it works perfectly in the conditions to which it was intended. There is, however, there is nothing unfair in the fact that the author of the genetic algorithm which went the way of the antenna has been attributed the authorship of the patent, as he wrote the program and devised selection criteria that led to the design patented. A genetic algorithm is a directed search method based on probability. Under a very weak condition (that the algorithm maintains elitism, ie, always save the best part of the population without making any changes) it can be shown that the algorithm converges in probability to the optimum. In other words, by increasing the number of iterations, the probability of having the best in the population tends to 1 (one).
