The genetic algorithm and its possible applications - page 6

 

The second (if I am not mistaken) law of Dialectics states that quantity (value) passes into quality (parameter/property). In this case, the optimization process, after n-number of iterations, must "automatically" generate new parameters as a "by-product" of its cycle. Further, resulting parameters can "clump" into groups and form new systems that will be gradually drawn into the "cauldron" of optimization and the process repeats again. A convection production of species with increasing complexity is obtained, moving on to further stages of evolution - cloning, crossbreeding, selection, etc...

How dialectics works in chemical and biological processes at the micro level I do not know, but in theory it all fits...))

 
Реter Konow:

I think it is unlikely. Based on the concept of GA, identical structures - clones of the same system with different parameter values - can interbreed. Different individuals within the same environment cannot interbreed in Nature either. This natural biological constraint stops the emergence of ridiculous, non-viable freaks that are meaningless to the ecosystem. Such "experiments" always end in failure and are only suitable for laboratory research. GA imitates biology and therefore, does not deviate from the principles of interbreeding, inheritance and selection.

The question, from a theoretical point of view, is very interesting. Evolution creates not only "optimised" versions of creatures in the course of their "adjustment" to conditions, but also fundamentally new species. Where do they come from if interspecies interbreeding is impossible? So they come from natural mutations. But, - mutation is a change in existing genes, not acquisition of new ones. That is, - the set cannot be increased, and "calibration" only adapts (optimizes) the living species. Where do new and more complex creatures come from?

Even if we make an algorithm randomly "cast" parameters into arbitrary systems and also randomly find an optimization target (fitness function) for them, what can it give us?

Agenetic algorithm is more perfect because it has no limitations, unlike a natural prototype.

About adaptability - evolution does not only follow the path of perfection (stronger, faster, tougher), but also the path of inevitable "deterioration". So, for example, nature could have created a monster the size of a killer whale, with a chitinous shell (the best material in combination of strength and weight), and with legs, even the cubs of such a species would have been invulnerable, but this did not happen, because very quickly the food base would have run out and all other species would have been destroyed on the planet and the species of this monster would have eaten itself in the end. That is why whales, felines and other predators are exactly the size and degree of vulnerability that would ensure survival. Vulnerability of a species is a necessary characteristic for survival, and invulnerable species starve to death. Humans are virtually invulnerable and can easily be pushed to the brink of extinction by the destruction of their 'food base'.

I agree about evolution and the necessary vulnerability of creatures. Just about the perfection of the GA is not. I believe it is only a tracing and very limited.

I am generally surprised at the evolutionary path Nature has chosen. After all, living species exist ONLY in an energetically charged environment (oxygen, chemicals consumed with food and water) and have no autonomous and independent source within. This is a much better solution. Make one energy source inside each being based on some powerful reaction (nuclear or chemical) and the being will become independent of oxygen, water, food and other things. Will be able to live in space and other conditions impossible for us.

For some reason, Nature did not go that way...

there are autonomous beings - bacteria with cholophilus. and some beings do not need oxygen and can survive in absolute cold as well as 600-800c in pressurized water.

the natural evolutionary mechanism is limited to combinations of amino acids and ha only limited by the imagination of its users.

 
About genetic selection of the strongest.
Nature manages to make defects in the genocode in addition to recording the best qualities, and it is such "defective" genes that are eventually assembled into the code that eventually survives.
Converting this into robot conditions, it is necessary that from set of conditions for signal trade the genetics besides a selection of the strongest makes "defective" genocode. like variables for input 6, the genetics picked up parameters, and on new generation starts pair tens descendants and among them does a marriage of 6 variables with picked up parametres + the 7th parameter.
And this is the version of genetics evolution that will return a trading robot with a self-developed set of genetic code.
A simple search of parameters for a steadily invariable set of variables gives only speed in selecting optimal values.
To implement such a complex task, we need a very large history of quotes and a no small set of variables. A stable condition must be that the variables are not less than a certain amount, the robot lives only if it generates profit and loses vitality at inactivity. Like if it is not trading, it will die.

Probably the energetic autonomy is rejected by Nature because of the lack of interaction and destruction of the motive for evolution. If beings do not devour each other for the sake of daily existence - they do not interact and therefore do not evolve. Consequently, autonomy destroys the foundations of Evolution, and limits life to a single cycle. A dead end...

Probably energetic autonomy is rejected by Nature due to lack of interaction and destruction of the base for development. If beings do not devour each other for the sake of daily existence, they do not interact and therefore do not evolve. Therefore autonomy destroys the basis of Evolution, and limits life to one cycle. A dead end...

Why evolve?

It is good enough for simple extremophiles, they do not need oxygen, they consume hydrogen sulphide - the main thing is to continue living.

 
Andrey Dik:

... Humans are a virtually invulnerable species and could easily be brought to the brink of extinction by the destruction of their "food base".

I agree.

 
Anatolii Zainchkovskii:
Regarding genetic selection of the strongest.
Nature manages to make defects in the genocode in addition to recording the best qualities, and it is such "defective" genes that are eventually assembled into the code that eventually survives.
Translating into robot conditions, it is necessary that from a set of conditions for a trade signal the genetics selects not only the strongest, but also makes a "defective" genocode. It is like 6 variables for entry, the genetics picked up parameters , and on the new generation starts a couple dozen descendants and among them makes a defect of 6 variables with picked up parametres + the 7th parameter.
And this is the version of genetics evolution that will return a trading robot with a self-developed set of genetic code.
A simple search of parameters for a steadily invariable set of variables gives only speed in selecting optimal values.

The problem is that you can't just "add a parameter" to the system. It doesn't work that way. The parameter is a derivative of the whole system. It is based on many functions and properties. It can't just be added...

I have an error there, not the 7th parameter, but the 7th variable. There are some difficulties, but it is possible to implement it, and even mt5 allows it, but the process of parameter selection through genetics cannot be screwed on.
