What you really want from optimisation forTCs? - Articles, Library comments

Vladimir Suslov #:

max = pi/2 + n*2*pi

where n is any integer

where is the restriction?

Can the period of the bag be a negative number? No? Here is the restriction from below.

can the period of the flywheel be greater than 10000? it can, but there is no sense in it, so here is the restriction from above.

etc. practical problems have constraints, that's why they are N-complete (though not only that) otherwise it makes no practical sense to apply optimisation algorithms - it will take a long time. think about it.

Any questions from newcomers Errors, bugs, questions Machine learning in trading:

Ah, sorry. Keep talking, sorry for interrupting your conversation.

On the topic of applying optimisation to TCs. It is difficult for me to imagine a TS that it is reasonable to optimise simultaneously for more than ten inputs.

Therefore, it seems that the "degrees of freedom" of a TS are less than a dozen. This includes some requirements for optimisation algorithms - coolness is no longer about universality (optimise a super-complex thing with a huge number of inputs).

I.e. for TC you need to understand what you really want to get from optimisation.

The field of application of optimisation of more than 10 parameters is vast.

The first is patterns.

Second - live portfolios.

Third - neural networks and combines, live "hardware"

Fourth - everything that can talk to us now from behind the screen will soon be even smarter thanks to self-adaptive systems with thousands, billions of parameters.

Life came about by optimising amino acids just as the first.... That's optimisation too, the first one to pass the Global Optimisation test.

According to this methodology, the Hilly function test.

Here, the picture has changed.

The top in the list of results PSO and IWDm showed values at the limits of the range, this is not very good.

OPTIMIZATION_METHOD_AO_GSA_Stars

GSA_Stars is just a toy, for visual simulation of bodies movement, can be removed.

And HS for some reason, very interesting algo.

Elite indicators :) Finally a REAL ECN Don't go to the

HS erorites for some reason, very interesting algo.

In Optimisation.mqh it is written about it.

// Optimization_C_AO_HS
#define  MACROS_OPTIMIZATION_INIT , 0.9, 0.1, 0.2, epochCount
  // Невозможно адаптировать без изменения исходника.
  // Совпадение имен: C_AO_HS::h[] и S_Harmony::h.

If you change the source (make name mismatch), I can adapt it.
