To keep programmers employed, burn CPU cycles, and find folks something else to do, this makes them feel better while they're losing money, until they figure out what might actually work.
So optimization gives programmers jobs? can you please explain here?
Yes, I agree the optimization takes a long time to run.
Can you please explain what you mean by this "this makes them feel better while they're losing money, until they figure out what might actually work."?
Writing countless optimisation systems over the decades has kept many employed, obviously excuse the overall tongue-in-cheek nature of my comment. Ditto I think it makes people feel better because they think the optimisation system is doing something productive for them, when in most cases it is an illusion.
Many users of optimisation do so under the mistaken belief that the past can predict the future, so if we have enough data and optimise accordingly, then it will predict the future better. Under this argument more data and more optimisation is therefore always seen as a good thing, sadly it only worsens the problem of curve fitting, usually in the absence of a meaningful model, at some level.
However, a knowledge of where we are in relation to the past and similar conditions that have occurred in the past is obviously an asset. If this is used in conjunction with a useful model on whatever timeframe you work, then useful results can be achieved, but in general the facts speak for themselves - most users of optimisation do not get much in the way of positive benefits, systems fail when they meet the real world and live data.
If you are serious in this area I would recommend looking at the work of folks like Kevin Davey @kevinkdog who do seem to 'get it' and make it perform profitably.
Optimizing a strategy does nothing more than curve fit the parameters to past data. It does virtually nothing to improve the strategy in the future. I learned this lesson many moons ago.
All optimization routines in software packages do is help sell the software,
Wow look at the advanced optimization capabilities of our software you will be able to fine tune your strategy for maximum profits at the click of a button.........
