the algorithms

The story places the invention of algorithms in the ninth century, by work and grace of the astronomer and mathematician Mohammed ibn-Musa andalusia Jwarizmi, hence its name. Development in the Al-Yebra mugabata-ways to allow a limited number of steps and clear indications of execution could solve equations of first and second grade.

From the simplicity of preparing a salad, the possibility of solving a complex problem that concerns us the algorithms are of inestimable help. Obviously this is a modern Trojan horse only shows its efficiency strategic development practitioners, when non-routine situations or even when using the many available algorithms for more complex situations.

It is in this ordered set of steps and limited, which specify the sequence of operations to be solved to solve the problems, which relies heavily on the use of algorithms. We can simply define the algorithms as a set of rules for solving a certain class of problems or as a way of describing the solution of a problem. His character gives the general condition of the algorithms transdisciplinary tool.

His character gives the general condition of the algorithms transdisciplinary tool.
And remember not to pass, that the algorithms are at the heart of computers and computer languages that are only half of expressing them. The general expressed above, requires those who seek to produce algorithms to break down problems into simple and concrete, with a limited number of steps in line with the same complexity and the need to make them easily understandable to anyone. It is necessary to clearly explain the order to follow.

As is easy to imagine, the initial step of this process is waived fully understand the problem, requirement to be able to analyze it and then choose the way forward. Once designed and ordered steps, you should opt for a formula or design as that of the flow charts or tables of the decision. The tables are the least used and like so many other things, it originated in the industry (GE), and Feinstein and Holland which introduced in medicine.

As stated above, the flow charts are used, their mission is to graph algorithms, which use a symbol that in practice very few respected but should at least take it into account. A flow is defined as a graphic, clear, concise outline of the sequence of actions needed to solve a problem.

This outline contains the steps of the algorithm, written in symbols, which are connected by arrows indicating the sequence of the flow of data and steps of execution of orders.

Legend of the algorithms

It uses a rounded rectangle for the initiation and completion of the algorithms, the lozenges are used for decisions and rectangles for actions to take. The arrows indicate the flow taking into account that the decisions ¨ no ¨ grow vertically and decisions ¨ Yes ¨ to grow right. While these are not the only symbols, our objectives are regarded as adequate.

One question that is often raised is whether the algorithms are always reliable, a question that deserves concern Renato Cartesius Virtudes
The algorithms give us the opportunity to select what is considered a priority, which is not little and thinking ability as computer starts its first step, which involves precisely defining the problem, which we know is itself a task Intellectual very important.

Printed in addition algorithms, sequential logic and clarity to both systematic processing of data and clinical tests and procedures and this course gives validity by contributing to improve our clinical trial, but even more because we consistently practice can improve care for our patients on many occasions.

There are many computer algorithms based on different degrees of evidence, which provide us with your application and also give us an important resource for research and medical education.

Disadvantages

We can say that among the most important is the ignorance of its existence and does not know its limits. These are possibly the most important, he joined the inability to convert what was stated in algorithms and the lack of availability, because while there is a significant amount of algorithms, for various reasons, only very few are used routinely.

Another drawback to consider is accustomed only to algorithms that are outside and pretend they are not, are not the truth, are just a tool and its efficiency will depend on the use made of it. One detail to consider is the existence of a proposal to establish a center algorithms.

In short we must consider that many of the problems depend on who are unaware of those who do not know their limits and those who overused. If we want greater clarity and recovery algorithms read the most appropriate reference that makes them Komaroff;

.......... while algorithms can play a role in making medical decisions, is unlikely to find a role in two other critically important aspects of patient care .... listen rioja that said, how you say and what is not said, and explain, and show that confidence is a concern. The algorithms are not a substitute for the experience sensitivity or compassion ... In our opinion, the algorithms can help us articulate how we take decisions, to clarify our understanding and to recognize our ignorance. We can help demystify the practice of medicine and to demonstrate that much of what we call the art of medicine is really a scientific process, a science that is waiting to be articulated.
